EXPLANATION OF TEST REPORT

Each tractor is a production model equipped for commonusage. Power consuming accessories can be disconnected onlywhen it is convenient for the operator to do so in practice. Ad-ditional weight can be added as ballast if the manufacturerregularly supplies it for sale. The static tire loads and the in-flation pressures must conform to recommendations in the TireStandards published by the Society of Automotive Engineers.

PREPARATION FOR PERFORMANCE RUNS

The engine crankcase is drained and refilled with a meas-ured amount of new oil conforming to specifications in theoperators manual. The fuel used and the maintenance opera-tions must also conform to the published information deliveredwith the tractor. The tractor is then limbered-up for 12 hourson drawbar work in accordance with the manufacturer's pub-lished recommendations. The manufacturer's representative ispresent to make appropriate decisions regarding mechanical ad-justments.

The tractor is equipped with approximately the amount ofadded ballast that is used during maximum drawbar tests. Thetire tread-bar height must be at least 65% of new tread heightprior to the maximum power run. .

BELT OR POWER TAKE-OFF PERFORMANCE

Maximum Power and Fuel Consumption. The manufac-turer's representative makes carburetor, fuel pump, ignition andgovernor control settings which remain unchanged throughoutall subsequent runs. The governor and the manually operatedgovernor control lever is set to provide the high-idle speedspecified by the manufacturer for maximum power. Maximumpower is measured by connecting the belt pulley or the powertake-off to a dynamometer. The dynamometer load is thengradually increased until the engine is operating at the ratedspeed specified by the manufacturer for maximum power. Thecorresponding fuel consumption is measured.

Varying Power and Fuel Consumption. Six different horse-power levels are used to show corresponding fuel consumptionrates and how the governor causes the engine to react to thefollowing changes in dynamometer load: 85% of the dyna-mometer torque at maximum power; minimum dynamometertorque, Yz the 85% torque; maximum power, Y4 and % ofthe 85% torque. Since a tractor is generally subjected to vary-ing loads the average of the results in this test serve well forpredicting the fuel consumption of a tractor in general usage.

DRAWBAR PERFORMANCE

All engine adjustments are the same as those used in thebelt or power take-off tests. If the manufacturer specifies a dif-ferent rated crankshaft speed for drawbar operations, then theposition of the manually operated governor control is changedto provide the high-idle speed specified by the manufacturerin the operating instructions.

Varying Power and Fuel Consumption With Ballast. Thevarying power runs are made to show the effect of speed-con-trol devices (engine governor, automatic transmissions, etc.)on horsepower, speed and fuel consumption. These runs arcmade around the entire test course which has two 180 degree

turns with a minimum radius of 50 feet. The d:-awbar pull isset at 3 different levels as follows: (1) as near to the pull atmaximum power as possible and stili have the tractor main-tain the travel speed at maximum hnrsepower on the straightsections of the test course; (2) 75% of the pull at maximumpower; and (3) 5°% of the pull at maximum power. Prior to1958, fuel consumption data (10 hour test) were shown only forthe pull obtained at maximum power for tractors having torqueconverters and at 75% of the pull obtained at maximum powerfor gear-type tractors.

Maximum Power with Ballast. Maximum power is measuredon straight level sections of the test course. Data are shown fornot more than 12 different gears or travel speeds. Some gears ortravel speeds may be omitted because of high slippage of thetraction members or because the travel speed may exceed thesafe-limit for the test course. The maximum safe speed for theNt;braska Test Course has been set at 15 miles per hour. Theslippage limits have been set at 15% and 7% for pneumatictires and steel tracks or lugs, respectively. Higher slippagegives widely varying results.

~

Maximum Power Without Ballast. All added ballast is re-moved from the tractor. The maximum drawbar power of thetractor is determined by the same procedure used for gettingmaximum power with ballast. The gear (or travel speed) isthe same as that used in the lO-hour test.

Varying Power and Travel Speed with Ballast. Travel speedscorresponding to drawbar pulls beyond the maximum powerrange are obtained to show the "lugging ability" of the tractor.The run starts with the pull at maximum power; then addi-tional drawbar pull is applied to cause decreasing speeds. Therun is ended by one of three conditions: (1) maximum pullis obtained, (2) the maximum slippage limit is reached, or (3)some other operating limit is reached.
