3.0 OPERATION


3.3 MACHINE COMPONENTS

The Lockwood Potato Windrower uses a digger section to bring the potatoes up from the ground onto the primary beltedchains. The primary belted chains then deliver the potatoes onto the secondary belted chain and the override belted chainwhere the vines are separated from the potatoes. The potatoes are then transported to the rear cross conveyor, whichplaces the potatoes in a windrow. The vines are then carried out the back of the machine.

3.6.1 ATTACHING IMPLEMENT TO TRACTOR

Always place the Lockwood Harvester on a hard, dry sur-face free of obstacles and debris. When ATTACHING themachine to the tractor, follow this procedure.

1. Clear the area of bystanders, especially small children.

2. Make sure enough room and clearance exists awayfrom obstacles to safely back up to the windrower.

3. Back the tractor up slowly aligning the pintle hitch ofthe windrower with the tractor drawbar.

4. Jack up the hitch to clear the tractor drawbar.

5. Connect the hitch of windrower to the tractor and se-cure with appropriate hardware.

6. Check the level across the harvester’s main frame

7. If the windrower is not level, disconnect the windrowerfrom the tractor and adjust the pintle up or down. (Fig.#22).

8. Clean and grease the PTO shaft of the tractor and theimplement end of the driveline input connection.

Fig. #23 Attaching driveline to PTO of tractor

IMPORTANTFor maximum efficiency the machine must be level dur-ing operation.

WARNINGHeavy tongue weight can cause severe injury or death.Support the jack and tongue securely. Approximatetongue weight is 10,000 lbs.

9. Connect the driveline (See Fig. #23) to the tractor byrotating the locking collar and simultaneously pushingthe driveline onto the tractor PTO shaft. Properly at-tach the implement end of the driveline to the harvesterand tighten all bolts to their specified torque.

NOTEThe tractor PTO must be Ø1-3/4” - 20 spline or Ø1-3/8” -21spline.

NOTECheck shaft articulation and clearance zone! Jointarticulation of more than 70 to 80 degrees leads todamage. Contact between implement input drivelineand tractor or implement (e.g. three point hitch, drawbar,hitch pin, jacks, etc.) leads to damage. Do not usetractors that have a PTO connection point does notallow the implement input driveline to articulate fullywithout interference.

WARNINGCheck the length of the telescoping members to ensurethe driveline will not bottom out or separate when turningand/or traveling over rough terrain. The implement manu-facturer should only modify the length of the implementinput driveline.

Fig. #22 Adjust pintle hitch to level the windrower


IMPORTANTWhen engaging or disengaging the PTO after hookup,run the engine at low idle speed.

10. Route and connect the hydraulic lines of the windrowerto the tractor. Attach the main control valve and lines tothe tractor. (Check the tractor operator’s manual or askyour dealer for information on hookup to the tractor’shydraulic system.)

11. Mount the electric control box in the tractor cab.

12. Route and connect wiring harness from the windrowerto the electronic control box in the tractor cab.

13. Start the tractor, activate hydraulic control valve thenoperate all control switches to activate each hydraulicsystem. Extend each cylinder to its maximum length.Check the tractor hydraulic reservoir to replenish thehydraulic oil.

14. Raise and lower the machine a few times to be sureeverything is secure, tight, and functioning.

3.6.1 ATTACHING IMPLEMENT TO TRACTOR (CONT’D)

This harvester control valve can be configured to operateas closed center or open center hydraulics. You canchange the control valve by changing the cartridges andplugs in the valve stack. See decal under valve stack coverfor instructions. For most tractors and harvesters withmotors, set the valve stack for open center, and set theflow of the valve stack from 2 to 3 gpm. Ask your dealerfor instructions.

NOTE


3.7 TRANSPORTING

The Lockwood Potato Windrowers are designed to easilyand conveniently move from location to location. When trans-porting the machine, review and follow these instructions:

3.8 DIGGING

The nose and the belted chain have been designed to dothe most efficient lifting of any machine in the industry. Ifnecessary, you can make fine adjustments to provide foran efficient harvest.


3.7.1 TRANSPORTING THE WINDROWERWhen transporting the machine, follow this procedure:

1. Attach the windrower to the tractor by following the procedure in section 3.6 of the manual.

2. Towing speed should not exceed 25 MPH (40 km/h). Theratio of the tractor weight to the windrower weight playsan important role in defining acceptable travel speed. Thefollowing table summarizes the weight ratio to travel speed.

Table # 1 weight ratio to road speed

Travel Speed

Weight of fully equipped or loaded implement(s) relative to weight of towing machine

Up to 25 M.P.H. (40 km/h) 1 to 1, or less

Up to 10 M.P.H. (16 km/h) 2 to 1, or less

Do not tow More than 2 to 1


B. Semi point blade with rod (rock blades) (See Fig. #27):Use this blade in sandy or light soil where rocks maybe present. This blade has a wedge on the back edgethat pushes rocks down, diverting them from the beltedchain as it cycles around the front rollers.

C. Clod blades (See Fig. #28):This blade works best in heavier soil that may pro-duce clods on the windrower’s belted chains. Unlikethe semi point blades the clod blade is not sharp atthe point but has a 1” bar at the front edge of theblade. This blade breaks the soil and will not leavelarge clods going up the digger bed. Instead, theblade breaks the large clods into more manageablesmaller clods.

A. Semi point blades (See Fig. #26):This blade works best in sandy or light soil withoutclods. At the proper digging depth, the blade mustcut slightly deeper than the belted chain’s positionotherwise, excessive wear will occur on the primarybelted chains and rollers. The blade’s pitch shouldbe steep enough not to allow the potatoes to come incontact with the belted chain until they are carriedaway.

3.8.2 DIGGER BLADE

Blade angle can be changed by loosening the rear bolt ofthe blade mounting brackets and moving the bolts up ordown in one of the holes in the frame. (See Fig. #25).

Types of Digger blades:

Digger blades are available for narrow and wide digger noses.The narrow digger nose is used with row widths of 32” & 34”and the wide digger nose with row widths of 36”- 40”.

3.8 DIGGING

3.8.1 DIGGER NOSE

The digger nose height can be adjusted with the two 1” nutsat the top of the lifting rod. Loosen the top nut and turn thelower nut down to desired lift height. Lock the top nut downon the adjusting nut to complete your change.

NOT SHOWN: The lifting rod has a spring under the mountingbracket that will put downward pressure on the digger blade.By raising the digger nose, the nuts will increase the downpressure.

Fig. #26 Semi point blade

Fig. #27 Semi-point blade with rods (rock blade)

Fig. #28 Clod Blade

Fig. #25 Digger Nose Assembly

E. Combination blades (See Fig. #29):The windrower can use combination blades in a vari-ety of soil conditions, except light sandy soil. Combi-nation blades have a scoop in the middle of the rowwhere potatoes are present. This scoop harvests allthe potatoes, but doesn’t promote digging excess soilbetween rows.

Figure. #29 Combination Blades

The digger nose is raised and lowered by 2 hydraulic cylin-ders, one on each side of the nose. Each side of the nosecan be raised and lowered independently or as a unit, withthe control box in the tractor cab.


Assuming the blade angle and nose roller relationship iscorrect, too much sag in the return side of the primary beltedchain can cause feed problems (See Fig. #32). Too muchsag causes the belted chain to drag along the ground, pull-ing soil back under the nose roller. The entry of this soil intothe crop flow pattern causes an obstruction. Dragging thebelted chain on the ground also greatly reduces chain life.

Properly adjusted (See Fig. #33), the digger blades will clearsoil away from the front of the belted chain. As the bladewears, adjust the nose rollers upward to a new setting torestore proper ground clearance with the blades. This givesyou the advantage of longer service life of the digger blades.

For the most effective action in heavy soil, set the noserollers slightly above the center line of the blades. This raisesthe soil as it passes over the blade onto the belted chain,causing a disintegrating action that begins soil breakup andseparation. Use the six holes located on the digger framewhen making this adjustment (see Figure #30).

3.8.3 NOSE ROLLERS

The nose rollers located at the forward end of the primary`belted chain can be adjusted up or down and forward orbackward by placing the nose roller bolt in the proper holesin the digger frame (see Figure #30). Make adjustments asneeded to change the nose roller position in relation to thedigger blades to meet varying soil conditions.

The relationship of the nose roller to the blade by soil typeswill affect the windrower’s efficiency and the life of the beltedchain. (See Fig. #30 through #33).

In loose soils, if the nose roller is set too high (See Fig.#31), the belted chain will push the soil forward and exposethe potatoes to the belted chain. The top of the blade shouldbe in line with the belted chain.

3.8 DIGGING

3.8.4 COULTERS

The coulters can be set on either side of the digger noseand nose wing. Three different types of blades are available.Larger diameter coulters help prevent boil out.

1) 24” notched coulters: These coulters work well in firmsoil to cut vines that may wrap around the digger nosewings. (See Figure #34).

2) 24” & 27” waffle coulters: These work best in sandysoil where the coulter may not turn as easily in thesoil. The waffle coulter, however, cannot run as closeto the nose wing as the straight coulter, increasingthe chance of wrapping (See Figure #35).

3) 24” Straight Coulter: The straight coulter is an all pur-pose coulter. The coulter will work in any soil type(See Figure #36).

Coulter Adjustment

The mounted coulters have heavy springs that allow adjust-ment (See Fig. #37) for the coulter to cross over stoneswithout causing harm to the disc or mounting frames.

To provide more downward pressure: Loosen the jam nutand tighten the adjustment nut.

To provide less downward pressure: Loosen the jam nutand loosen the adjustment nut.

After adding pressure to the coulters, raise them with thehydraulics using the UP switch on the control box. Be care-ful as you near the top of the cycle to be sure the coulterdisc is not hitting the main frame of the windrower. If thedisc hits the frame, lower it using the adjusting nut to aposition that does not allow it to hit the frame.

After positioning the coulters, check the length of the shaft.The excess shaft could snag and drag vines from the nextrow. If desired the excess shaft length can be cut off to avoiddragging vines.

The coulters serve 3 main functions:

1. Cutting the vines to prevent wrapping on the front edgeof the wing.

2. Cutting the soil profile to help funnel material into thedigger nose.

3. Prevent drifting on hills.

The coulters are raised with 2 hydraulic cylinders and canbe raised simultaneously or individually.

NOTERaise the coulters before turning.

3.9 PRIMARY BELTED CHAINS

The primary belted chain is located in the digger section ofthe windrower (See Fig. #38). The belted chain is either fullwidth or split and is made up of ½” (13mm) rods. The rodcomes in various patterns and pitches designed for differentsoil conditions.

See Sec 6.2 and 6.3 for rod and pattern recommendations.

3.10 SECONDARY BELTED CHAINS

The digger (primary) section of the harvester places the po-tatoes on the override and secondary belted chains (SeeFig. #39). The potato has a small drop from the diggersection of the windrower to the secondary belted chain. Arubber cushion on the override and secondary belted chainsprevents the potatoes from bruising.

The secondary belted chain carries the potatoes onto therear cross conveyor.

If excess dirt exists, have the rollers positioned so that theyare touching the rods, as opposed to underneath the belt.This shakes the belted chain and allows excess dirt to fallthrough the belted chain, without damaging the potatoes.

The secondary belted chain discharges to two locations.One half of the belted chain discharges to the front of therear cross and the other to the rear. This allows the pota-toes to spread out on the rear cross conveyor.

Fig. #38 Primary Belted Chain

Fig. #39 Secondary Belted Chain


An adjustable speed hydraulic motor drives the rear crossdischarge. The motor should be just fast enough to keepthe potatoes from being pulled off of the rear cross by thesecondary belted chain.

WARNINGNever attempt to clean a machine that is running.

The rear cross conveyor (See Fig. #41) transports the pota-toes to the ground, between the rows, where the harvestermay pick them up.

The rear cross is adjustable in and out by loosening (4) ½”and (4) 5/8” bolts on the side of the discharge portion of therear cross. Before harvest is started, adjust the rear crossto discharge the potatoes between the rows.

The discharge adjusts up and down with a hydraulic cylin-der with the control located in the cab.

3.12 REAR CROSS CONVEYOR

3.11 OVERRIDE BELTED CHAIN

The override belted chain (See Fig. #40) carries the vinesand trash through the windrower onto the ground at the rearof the windrower. The optional snapper rollers are designedto pull the clinging potatoes from the vines. The overridebelted chain runs above the secondary belted chain.

NOTENever allow the override belted chain to run too close tothe ground. This causes vine rolling.

Fig.#41 Rear Cross Chain

Fig. #40 Override Belted Chain As a result of raising or lowering the rear axle (see section3.13), an adjustment must be made to lower or raise therear cross (See Fig. #42). On each rear side of the rearcross is a “J” bolt, which functions to lower the back of therear cross. A good starting point is to have the rear crossset at 5-10 degrees. If the rear cross is too flat the second-ary belted chain may carry potatoes back and to the ground.The amount of setback should increase in hilly conditions.

The back of the rear cross is adjustable up and down toallow the potatoes to roll and avoid being caught by thesecondary belted chain. The adjustment for the rear crossis a J bolt (See Fig. #42) that holds the back of the rearcross. Loosening this will allow the assembly to move upand down as necessary.

Fig. #42 J-bolt adjustment

J-BOLT


3.13 REAR AXLE

The rear axle of the windrower (See Fig. #43) is adjustableup and down. The higher the back of the windrower is raisedthe more dirt will be separated. However, this increases thechances of skinning potatoes as they climb on the beltedchain. If this happens, decrease the PTO speed and in-crease the ground speed or lower the rear of the windrower.

The adjustment on the rear axle allows a total of 8” up anddown movement. The machine is shipped in its lowest posi-tion.

To raise the machine turn the 2 ratchet jacks (See Fig. #43)at the same time. When you are at the desired height checkthe rear frame with a tape measure (distance between up-per and lower tubes) to be sure they are at the same height.

3.14 REAR WHEELS

The rear wheels are adjustable to fit a variety of row spac-ings ranging from 32” - 40”. To adjust the rear wheels, followthese steps:

1. Jack the back axle off the ground to remove weight off thetires.

2. Remove the axle bolts that hold the adjustable axle inplace.

3. Remove the two bolts in the tie rod.

4. Remove the wheel bolts from both wheels.

5. Pull out the adjustable axle until it is placed at the de-sired row spacing.

Be advised that raising the rear of the machine up will flattenthe rear cross conveyor. See section 3.12 for adjustmentinstructions.

Fig. #43 Ratchet Jack

6. Adjust the tie rod in or out until the desired row spacingis set. The front of the tires should be set 1” narrowerthan the rear, measured at the center of the front and rearof the tires.

7. Place all bolts back into their respective holes.

8. To fine tune the tie rod setting, adjust the jam nut.

9. Remove the bolts from the metal flange that connects thesteering cylinder to the cylinder mount. The cylinder mounthas pre-drilled holes that fit different row spacing set-tings. Set the steering cylinder in accordance with youraxle row spacing setting.

10. Adjust the steering indicator rod so that the rod lines upwith the middle of the R/L decal (see Figure #46 on thenext page).

3.16 OPTIONS

3.16.1 VINE CHOPPER

The vine chopper is mounted to the windrower frame in frontof the rear wheels and in back of the override discharge. Thelifting action of the rotor picks the vines off the override beltedchain, carries them into the stationary knives and cuts theminto 4- to 6-inch pieces. The vine chopper eliminates blow-ing of heavy vines into undug rows, vine wrap on truck drivelines, and one tractor and disk operation.

The components are designed for long life with heat-treatedflails running on hardened bushings. The stationary knivesare also heat-treated. The vine chopper is powered througha drive line equipped with an overrunning clutch and beltdrive. The clutch will “free wheel” when the tractor PTO isdisengaged. The clutch will pick up smoothly and in combi-nation with the belt drive, eliminating shock loads to thedrive assembly. The rotor is balanced to eliminate vibrationduring operation. The desired operating speed of rotation ofthe vine chopper is 1150 R.P.M.

In extreme wet conditions, it may be necessary to reversethe stationary knives to keep the chopper from plugging.When it is reversed, the chopper will still shred vines, how-ever the pieces will be larger.

3.16.3 SNAPPER ROLLER ADJUSTMENT

3.16.2 SNAPPER ROLLERS

Snapper rollers (See Fig. #49-50) are available to removepotatoes from green vines. The assembly consists of tworollers with the override belted chain running through it. Thesnapper rollers are mounted on a hinged frame allowing theheavy foliage to pass between the roller. The hinged frameshould be adjusted so the rollers just clear the belted chain.Constant bouncing on the belted chain will cause unneces-sary noise and wear. Adjusting is made by raising or lower-ing the snapper rollers.

The top roller pushes the potato down where it is pinchedfrom the vine (See Fig. #49). The vine then travels betweenthe two rollers and the potato falls into the rear cross. Thetop roller has belts that can raise it off the override beltedchain when digging in dead vine crops. If the roller is notneeded to remove potatoes it should be positioned all theway up, out of the way of the vines.

3.16.4 SHAKERS

Shakers are used in the digger section of the windrower.The digger section is where 80 percent of dirt is removedfrom the crop. The types of shakers used are as follows.

Hydraulic adjustable manual shakers (See Fig. #51) imple-ment a 3 or 4 prong shaker attachment connected to a hy-draulic cylinder. When the operator moves the switch on thecontrol box, the hydraulic cylinder extends or retracts andan eccentric raises or lowers the shakers for more or lessshake. This type of shaker bounces the potato and willcause damage to the potato if the operator does not usecaution.

Hydraulic adjustable manual shakers:


Oscillating shakers:

Oscillating shakers (See Fig. # 52) are a more bruise-freemethod of separating dirt from potatoes.

With the oscillating shakers, a hydraulic motor rocks a shaftwith rollers on it. This produces a frequency in the beltedchain that is used to break up the soil while not bouncingthe potatoes. Run the shaker only as fast as necessary, asdamage to the potatoes will occur with excess speed.

Oscillating Shaker Adjustment:

The oscillating shaker is controlled by a wide variety of ad-justments. The main adjustment is the speed of the hydrau-lic motor. This is adjusted with the speed control switch onthe control box or the tractor flow control.

The shaker can be adjusted by changing the stroke of theshaker (See Fig. #53). This is adjusted by placing the shakerin the various stroke adjustment holes.

Hydraulic single shaft shakers:

With the single shaft shakers a hydraulic motor turns a shaftwith rollers on it. This produces a high frequency that breaksup the soil while not bouncing the potatoes. The shaft canbe raised or lowered from each side of the nose by adjustingthe take-up bolt. Raising the shaft increases dirt removal.Run the shaft speed only as high as necessary, as damageto the potatoes will occur with excess speed. The speed ofthe motor can be controlled from the operator control box,or the tractor flow control.

If the windrower is not equipped with an optional speedcontrol, operate the shaker from the remote valve of the trac-tor with a flow control valve. More oil flow to the shaker mo-tor provides a higher frequency of agitation, while less oilflow provides lower frequency for more aggressive agitation.

Single Shaft Shaker Adjustment:

To adjust the shaker (See Fig. #55) follow this procedure.

1. To raise the shaker shaft, loosen the lower jam nut,turn the upper jam nut clockwise until you havereached the desired height. Then tighten the lowerjam nut to the specified torque.

2. To lower the shaker shaft, turn the upper jam nutcounter-clockwise until you have reached the desiredheight. Then tighten the lower jam nut to the speci-fied torque.

3.16.5 THIRD COULTER

The third coulter is designed to run in-between rows wherepotatoes from the windrower are being placed, clearing therow of trash. The coulter accomplishes this objective with asingle disc or pair of discs.

There is a manual adjustment on the arm of the coulter thatcan be adjusted with a spring to keep it at the proper depth.

The operator must be sure to raise the coulter before turningon the end of the field. The coulter must be locked, with alock pin, in the mount of the coulter when transporting thewindrower on the road. Be sure to remove the pin beforeattempting to lower the coulter.

The coulter is raised with a hydraulic cylinder operated fromthe control box in the cab of the tractor.

3.16.6 GAUGE WHEELS

Gauge wheels (See Fig. #56) are mounted to the diggernose of the windrower to keep the proper desired depth whendigging in uneven field conditions. There are manual adjust-ments on each wheel and bolts on each side of the wheelmount to set the wheels at the proper depth and spacing.The wheels raise and lower the digger nose.

3.16.7 ROLLER SCRAPERS

Roller scrapers (See Fig. #57) are offered to remove soilbuildup on belted chain rollers. Clockwise or counterclock-wise scrapers are required, depending upon the rotation ofthe roller. Make sure the beveled edge of the scraper feedsinto the rotation of the roller.

If the scraper is assembled incorrectly, soil will collect un-der the scraper, act as a brake and stop the rotation of theroller. When the roller stops damage will occur to the rollerand the belted chain.

3.17 OPERATING HINTS

3.17.1 PREPARING SOIL AND CROP

Many people plan their farming operations long before har-vest time. The long range planning can well include mea-sures that will increase harvesting efficiency, as well asyields. Here are some reminders and suggestions.

1. If soil is exceptionally rocky, consider clearing the groundbefore planting to reduce the chance of damage to theharvesting equipment later.

2. When planting and cultivating, avoid soil compaction asmuch as possible. Proper tillage will reduce clods andspeed up decomposition of organic material. Irrigationalso helps to reduce clods before harvesting.

3. Weeds and trash reduce harvesting efficiency and cancause mechanical difficulties. Removal through mechani-cal or chemical means is recommended.

3.17.2 ADVERSE CONDITIONS

Lockwood has available special belted chains designed forharvesting potatoes in varying and extreme conditions. Inmany cases, changing to one of these special belted chainswill enable the machine to keep harvesting when others havestopped.

Primary belted chain is available in pitches of 32 to 60 mmin belted chain for harvesting in various soils conditions wetor extremely heavy soil.

3.17.3 HARVESTING EFFICIENCY

Studying procedures and facts of mechanical digging andwindrowing can help operate the Windrower at maximumefficiency with minimum cost.

A potato windrower normally works under a heavy load. Foreach 1/2" of depth, a digger blade lifts an average of 150tons of soil per acre. Digging 4 rows at a speed of 2 m.p.h.with the digger blades at a depth of 4" means that the beltedchains are lifting an average of 12 to 20 tons of soil perminute. Operating just 1/2" deeper requires the belted chainsto lift another 2 tons or more of soil per minute. Each ton ofdirt lifted requires more power and fuel expended, yet mayproduce only a few more potatoes. Thus, maximum har-vesting efficiency and economy may mean recovering less

than 100 % of the crop. The additional power, fuel, and timerequired to lift an extra inch or two of soil, plus the probabil-ity of reducing the separating efficiency, may be more ex-pensive than the value of a few potatoes left in the field. Forexample, digging 98% of your potatoes may result in morenet profit than lowering the digger two inches deeper anddigging 100%. This is a factor to consider as you begindigging. Compare costs of maximum recovery and maxi-mum efficiency in determining the most efficient digging depthin your situation.

Regardless of digging depth, blades should scour freely forbest digging action. Watch for spill-out around the ends ofthe blades. Excessive spill-out may mean that another typeblade is required or that the speed of the primary beltedchain is too slow relative to forward travel speed.

Carry the soil two-thirds or three-fourths of the way up theprimary belted chains. This provides maximum protectionfor the potatoes. Separation of the soil is determined by thepitch and speed of the primary belted chain and the amountof shaker agitation. The lower belted chain shakers performmost of the agitation needed for proper separation.

The primary belted chain normally used is 45 - 56 mm pitchbelted chain on the primary digger section and 45 mm - 50mm pitch with rubber covering on the secondary section.These pitches are designed for the best separation underthe widest range of conditions. Other patterns and pitchlengths are available from a Lockwood Dealer.


3.18 LOW DAMAGE OPERATINGHINTS

Lockwood has always recognized that potato bruising con-cerns the grower greatly and constantly searches for im-proved methods of bruise reduction. Proper operator train-ing has the most effect on potato bruising and is the mostcontrollable. The following section on low damage harvest-ing contains suggestions for the operator and discussesmachine functions which you may use to maximize the quali-ties built into the Lockwood windrower.

3.18.1 DIGGER BLADES:

The performance and depth control of the digger blades willhelp control bruising. Adjust the blade, regardless of type,for the proper digging angle to allow correct feeding of pota-toes into the primary belted chain. Adjust blades so thatpotatoes do not bump into the front of the primary beltedchain. Keep the blades scoured and sharp to maintain evenflow of dirt and potatoes into the primary area. Improperblade angle or poor scouring will cause the potatoes to “boil”ahead or spill out the sides of the digger nose.

Digging too deeply will result in carrying much more dirt intothe machine than necessary and will increase the amountof power required to pull the windrower.

Operating at too shallow of a depth will cause the blades tocut potatoes or miss them entirely. Check the digging depthat the beginning to verify proper harvesting of the crop.

3.18.2 BELTED CHAINS:

The belted chains in the windrower perform two major func-tions: they convey the dug material and provide separationof the soil and trash from the potatoes. The belted chainpitch determines the capacity of the belted chains. The beltedchain speed and forward windrower ground speed affectsthe material volume the belted chain can carry. In order toobtain the lowest crop damage possible, maintain a properloading on the belted chains. Provide potatoes with a “cush-ion” to minimize damage while eliminating as much dirt andtrash as possible to achieve proper loading.

Primary Belted Chains:

The primary belted chain elevates the potatoes out of theground. The process of separating dirt and trash from pota-toes begins in the primary belted chain. The primary beltedchain should eliminate at least 80% of the soil by the timethe potato reaches the next belted chain. The soil carriedup the belted chain will provide a slight cushion for the pota-toes. Changing either the belted chain speed or the forwardground speed will change the amount of dirt carried up thebelted chain.

Rear Cross Belted Chains:

The rear cross belted chain is the first change of directionfor the potatoes in the windrower. The rear cross belted chainmaintains proper loading procedures since a high percent-age of bruising occurs at drops where flow direction changes.

Recommended belted chain speed to ground speed ratio forrear cross belted chains should be about .5. Keep the rearcross belted chain as full as possible without allowing spill-out or roll-back under the secondary belted chain.

Rear cross belted chains should always have some type ofrubber covering. See section 6.4 in this manual on chaincoverings and descriptions.

Run the primary belted chain speed slightly faster than theforward ground speed, usually at a ratio of 1.0 - 1.2 for sandysoils and 1.3 - 1.5 for heavier soils. Operators may have toadjust these speeds to keep the belted chains full, depend-ing on harvesting and yield conditions. Adjust speeds bychanging the hexagonal bore sprockets on the primary drive.

In heavier soil conditions, use shakers. Adjust shakers toallow desired amount of shaking action.

Secondary Belted Chains:

The secondary belted chain provides additional soil separa-tion and has a rubber covering to provide protection frombruising. The secondary belted chain normally has a pat-tern that includes down rods to prevent rollback and to carrythe potatoes up the steeper conveyor.

The primary belted chain will eliminate most of the soil bythe time the potatoes reach the secondary belted chain.Therefore, run the secondary belted chain much slower thanthe primary belted chain. Place the belted chain speed toground speed ratio for the secondary belted chain at about.5; however, the secondary belted chain speed should neverrun slower than 1.1 mph (96 feet per minute) to provide properloading onto the rear cross belted chain. The operator setsthe belted chain speed to keep the belted chain as full aspossible without affecting delivery onto the rear cross beltedchain. Adjust speeds by changing the hexagonal boresprockets on the main drive.

Use chain patterns in the primary belted chains to carrypotatoes with a minimal amount of roll-back. Do not use aone up, one down chain pattern that pinches potatoes whenconcerned about bruising.

Summary

Many factors affect bruising that have not been mentionedin this section. However, maintaining the proper belted chainspeeds in order to keep the conveyors full while eliminatingas much dirt and trash as possible will result in a muchhigher percentage of bruise free potatoes. For additionalinformation on reducing potato bruising, consult yourLockwood dealer.


3.19 STORAGEAfter the season's use, inspect the machine thoroughly andprepare for storage. Repair or replace any worn or damagedcomponents to prevent any unnecessary down time at thestart of next season.

3.19.1 POST SEASON MAINTENANCE

To insure a long, trouble free life, this procedure should befollowed when preparing the unit for storage:


2. Thoroughly wash the entire machine using a pressurewasher to remove all dirt, mud, debris or residue. Becareful not to force water into bearings. If componentsstick or corrosion appears, clean more frequently. Dur-ing the final rinse, add a good disinfectant to the pres-sure washer tank to disinfect the machine.

3. Inspect the following components:

Soil Engaging Components:

A. Check for worn or damaged coulters.

B. Check Digger Blades for excessive wear.

C. Check nose wings for excessive wear.

D. Check all chain types and sprockets for excessivewear.

Electrical system:

A. Check the wiring harness and all wiring for damagedor worn areas. Check for cracked or worn insulation.Replace any components that have come in contactwith moving parts and route them to prevent damagein the future.

B. Check all hydraulic solenoids for loose or damagedwires. Repair or replace as required.

4. Make a list of all parts needed for repairs and orderthem immediately. Perform repairs when time per-mits and prevent unnecessary down time at the startof next season.

5. Relieve roller chain and V-belt tension.

6. Lubricate all grease points to remove any water resi-due from the washing and prevent rusting during thestorage period. Rotate all moving parts to distributelubricant to all surfaces.

7. Coat each roller chain with a good quality chain lubri-cant to prevent rusting. Rotate the roller chain slowlyby hand to cover all surfaces.

Pull telescoping members without fittings apart andadd grease manually.

4.2 MAINTENANCE

4.2.1 PREVENTIVE MAINTENANCE

WARNINGDo not attempt to clean trash out of drive chains whilethe windrower is running.

Preventive maintenance spots potential trouble and fixing itbefore it occurs. The savings from preventive maintenancecan be tenfold the time spent in performing it.

1. Whenever stopping the machine for lubrication and atrow ends, workers should clean vines and trash fromthe return side of the belted chains and from sprock-ets. Cleaning will prevent buildup of materials and un-necessary trouble.

2. When lubricating, check sprockets, idlers and bear-ings. Inspect sprockets for proper alignment.

3. Keep belted chains clean to prevent them from get-ting “stiff” or losing their flexibility. A “stiff” belted chainwill cause excessive sprocket wear.

4. Periodically, check to make sure that the return sideof the primary belted chain is not dragging on theground.

5. When replacing belted chains because of wear, checkthe sprockets carefully. Replace worn sprockets atthe same time or they will cause rapid wear of thenew belted chain.

6. Always maintain the hydraulic fluid at the proper levelin the tractor hydraulic reservoir.

7. Check all chains for correct tension and alignment.

8. Check for excessive wear on any of the machine com-ponents. Inspect for loose or missing bolts or com-ponents.

WARNINGPlace all controls in neutral or off, stop tractor engine,set parking brake, remove ignition key, wait for all mov-ing parts to stop, then properly block machine beforeservicing, adjusting, unhooking, attaching, repairing, orunplugging.

4.2.2 DRIVE CHAIN TENSION

Adjust the drive chains for the appropriate amount of slack.With the idler in place and tightened, measure the slack inthe part of the drive chain that will run in tension. Using astraight edge across the driving sprockets, press the spanof the drive chain down in the center and measure the sagas in the diagram. Use the following table to determine thecorrect tightness.

4.2.3 DRIVE BELT TENSION

Do not pull V-belts exceedingly tight to obtain the propertension. Tighten V-belts only enough to drive the load.Tighten adjustment eye bolt so a 1/32” - 1/16” gap existsbetween the coils of the spring.

Keep belts free of oil and sunlight as much as possible.Mineral oil is especially harmful. To clean, use a dry cloth orsoap and water and rinse well. If grease or oil has come incontact with a belt, clean with carbon tetrachloride. Neveruse belt dressing.

4.2.5 REPAIR OF BELTED CHAIN


Fig. #60 Align holes in clips with a punch.

When a belted chain needs repair, change out the entirechain and replace it with a spare. Repairs then can be mademore easily in the shop rather than in the field.

A. When removing the belted chain from a machine, slowlyturn the chain until the master link (See Fig. #60) sitson the bottom where the most slack exists. Pull theconnector clips together and remove the master link.

B. Do not pound on the ends of the master link with ahammer. Pounding will flatten the ends and make laterremoval more difficult.

C. Assemble in the same manner, checking to see thatthe male connector clip rests properly on the masterlink.

D. When replacing a rod or clip, the heads of the rivets willhave to be cut or ground off. When replacing clips besure to replace them in pairs to avoid unequal lengthbelts. When replacing rods, use correct length, diam-eter, style and rivet size. Use new backing plates whenreplacing rods.

E. Use a line punch or similar tool and align the holes inthe belt with the clip or rod and backing plate (See Fig.#60). Clamp materials together tightly.

F. Use the proper length and diameter of rivet for the appli-cation, making certain the rivet is properly seated.Pound the rivet to reassemble (See Fig. #60).

NOTEReassemble rods and clip with bolts. See your autho-rized dealer for replacement parts.

Fig. #59 Belted chain

To prevent major breakdowns or failures, periodic checksshould include inspection of worn clips, worn master links,worn chain, broken rod links, missing rivets, loose rivets,defective rollers, worn sprockets, and torn or cracked belt-ing.

Connector clips and connecting master links (See Fig. #59)will usually wear out first. Check connector clips and mas-ter links and change on a regular basis. A web chain maylast through two or three sets of connector clips. A spareweb chain will reduce down time.

Proper adjustment of the slip clutches will prevent seriousdamage to the machine. Tighten slip clutches only enoughto carry the load. Excessively tight clutches will not slip andcould cause extensive damage to the belting should a for-eign object get caught in the chain. The slip clutches alsoprotect other components in the drive train from damagedue to excessive power surge requirements.

Change all defective rollers immediately to prevent damageto the belting.

You can double sprocket life by changing the sprocketsside for side so both faces of the tooth wear an equal amount.

4.2.6 CHANGING HYDRAULIC OIL FILTER USED ON THE ELECTRO-HYDRAULIC VALVES

The major cause of hydraulic valve failure is contaminantssuch as dirt, rust, metal filings or sludge. Contaminantscause valve spools to stick, plug small passages, or erodecomponents until the valve leaks. When servicing the valvestake extreme measures to keep the valve components clean.

To prevent hydraulic valve failure, REPLACE FILTER ELE-MENT at the beginning of every season. (See Fig. #61)

WARNINGInjury or death may result if a cylinder loses pressureand suddenly retracts or extends. Block up or lowerthe nose lift and the coulters. Move the control switchesto release the pressure in the system before discon-necting any hydraulic connections.

WARNINGHydraulic fluid under pressure can pierce the skin, caus-ing injury or death. Do not expose bare skin to pressur-ized hydraulic fluid. Use eye protection and appropri-ate protective clothing to prevent injury. If skin is punc-tured, seek medical help immediately.

Fig. #61

To change the hydraulic oil filter:

1. Using a 5/8” wrench, remove plug #1.

2. Remove the old filter, taking the spring out.

3. Place the spring into the new filter.

4. Insert the new filter.

5. Replace plug and tighten

4.2.7 BLEEDING THE HYDRAULIC SYSTEM

After the system is bled, adjust the flow control of thetractor’s remote hydraulic outlet to the appropriate flow rate.The electro-hydraulic valve is supplied all by the remote trac-tor outlet. Excessive flow will potientially overload the trac-tor with heated hydraulic oil that could damage the tractor’shydraulic system.

WARNINGHydraulic fluid under pressure can pierce the skin, caus-ing injury or death. Do not expose bare skin to pressur-ized hydraulic fluid. Use eye protection and appropri-ate protective clothing to prevent injury. If skin is punc-tured, seek medical help immediately.

Fig. #62 Bleeding the system

Periodically air may become trapped in the hydraulic sys-tem. After working with the hydraulic system, “bleed” airfrom the system. Where hydraulic oil will not compress, airwill compress. Therefore if any air pockets or bubbles existin the cylinder, it will become “spongy” and will not hold itsposition. Cycle cylinders completely several times to purgeair. If air still sits in the cylinders, bleed them as follows(See Fig. #62):

1. Begin this operation by first loosening the clevis end(“B”) fitting about one full turn. Cover this fitting with atowel or rag to prevent the spray from hitting you or themachine.

2. Activate the appropriate switch to retract the cylinder.Release switch to its neutral position when fluid startsto spray from the loose fitting. Tighten this fitting andretract the cylinder fully by activating the appropriateswitch.

3. Loosen the plunger end (“A”) fitting and repeat the pro-cedure as used on the retraction, only this time extendthe cylinder.

4. After completing the system bleeding, check the fluidreservoirs for oil level.

6.2 CHAIN PITCH AND ROD CONFIGURATIONS

The belted chain comes in various pitches, configurations and patterns. These options will help to increase or decrease soilelimination, maximize conveying capacity, and protect potatoes from damage.

In the figures below, the circles represent the rods in belted chain. The center to center distance between the rods definesthe chain pitch. The “A” measurement represents the opening between the rods that dictate the size of objects such asclods, stones and small potatoes to be removed.

Use rod configurations in straight, offset up and offset down “patterns” to accomplish a purpose based on field conditions.

The two belted chains with belt dimensions of 60mm (2.36”) are the full width chain and the single chain. The single chainhas 2 plys of polyester nylon and the full width chain has 3 plys of polyester nylon. A third type of belted chain, the flexchain, has 2 plys of polyester nylon, with a center ply that measures 120mm. These 3 belted chain designs provide thecombination of strength and flexibility required for all applications.

6.3 CHAIN PATTERNS

“Pattern” chain is a combination of straight and/or offset links arranged in various repetitive sequences. The purpose of a“pattern” is to meet various conveying, cleaning or damage prevention conditions.

An all straight link pattern creates a flat surface for minimum separation. Use this pattern in loose soil conditions to carrysoil as far as possible up the belted chains, thereby minimizing potato bruising.

An all down link pattern has the same characteristic as all straight in that it creates a flat surface for minimum separation.Again it carries the soil further up the chain for potato protection.

Using a combination of up/down links will create deeper pockets. Notice in (Fig. #69) the up/down pattern creates more ofan opening between the rods than the straight/up link pattern does. On a 50mm (1.96”) pitch chain: with a straight/uppattern, the opening is 1.53” while an up/down pattern provides a 1.71” opening.

6.3 CHAIN PATTERNS

The straight/down/down pattern creates a shallow pocket. This is commonly used in preventing rollback.

Use of two down rods extends the length of the pocket. Using an up rod with the down rods creates a maximum openingbetween the links. This up/down/down pattern breaks the surface and makes the belted chain more aggressive in soilremoval.

A long deep pocket such as created by the straight/down/straight/up will hold a considerable amount of material. This iscommonly used in rocky areas. The use of the straight link in the pattern cuts down on soil separation and closes theopening versus the up/down pattern.

In general, when conditions are wet, more separation between soil and potatoes is desirable. Increase the pitch in wetconditions to reduce the soil build up on the rods. When conditions are dry, use an all straight pattern to carry more soil.Carrying more soil acts as a cushion protecting potatoes from damage by the steel rods.

6.4 CHAIN COVERINGS

6.4.1 PEGS

Pegs are rubber fingers that stick up off the rod that prevent rollback of the potatoes. These pegs stick up 2.5 inches fromthe top of the rod and are spaced 3.38 inches apart. See figure below.

6.4.2 FLIGHTS

Flights are rubber flaps that extend the length of the rod. Two flight types are used; B flight and C flight. Each respective flighthas a different height measurement; B flight has a height of 2.5 inches from the top of the rod and the C flight has a heightof 1.5 inches from the top of the rod. See figure below.

Figure #71 Pegs

Figure #72 Flight


6.4 CHAIN COVERINGS

Using chain patterns enhances the primary belted chain’s ability to seperate soil from the potatoes. Once the potatoesreach the secondary belted chain much of the soil is eliminated. At this point various belted chain coverings in combinationwith chain patterns are used to help convey and reduce bruising of the potatoes. The following is a description of availablecoverings, with illustrations, to show the openings between the links based on common belted chain pitches. Rod diameter,pitch and coverings will change the opening between the rods.

6.4.3 RUBBER COVER

The rubber cover is an extruded rubber tube which is applied over the belted chain rod. The tubing has a wall thickness of1/8” to 3/16”. The covering is simple but effective for use where protection is desirable but ultra soft handling isn’t necessary.Note how the combination of the rubber cover and belted chain pitch can vary the opening between the rods.

6.4 CHAIN COVERINGS (CONT’D)

Pillow cushions are extruded double wall rubber tubing with four continuing air shafts that run the entire length of the tubing.It was designed so that no matter how the potato hits the tubing, the tubing will flex. This flexibility also gives it self-cleaningability. Note how the rod opening can be varied by combining the rod covering with different chain pitch in the examplebelow.
