WHAT SHOULD I KNOW ABOUT THE DIETRICH CONICAL BLADE ROTARY INJECTOR?

The 2016 Dietrich Conical Blade Rotary Injector was sold for 2015 Fall and 2016 Spring use.

Market research told us customers perceived it to be too lightweight. While there have been

NO WARRANTY CLAIMS on these earlier units, a much stronger 2017 Dietrich Conical

Blade Rotary Injector was designed to alleviate customer concerns.

! The mount, U-Bolts, & coulter pivot have all been “beefed up” for an even stronger

injector.

! Like the Dietrich Sweep Injector, the Dietrich Conical Blade Rotary Injector is made

with hi tensile steel. Hi tensile steel is specially designed to handle high amounts of

stress without breaking or becoming deformed.

! The exclusive swivel conical blade system allows each single unit to pivot without high side loads.

! The conical coulter with a coil spring allows 5+ inches of rock clearance and provides

a shock absorber when striking a rock eliminating the need for a hydraulic trip system

and required maintenance. Injectors that utilize a C shank for rock protection have a

much shorter vertical travel than the Dietrich Conical Blade Rotary Injector. When a C

shank injector strikes a rock, the tool bar is violently forced up creating excessive

shock loads. The C shank injector must be very heavy to withstand these excessive

forces.

! The Dietrich Conical Blade Rotary Injector can be adapted to fit virtually every size tool

bar. In most applications no changes to the down pressure cylinder length are

required.

! Injector spacing can range from the standard 30” down to 18” with the injectors offset

for higher GPA. Example: 5000 GPA on 30” spacings would increase to 8300 GPA at

18” spacings.

Customers have asked about “No Grease” Injectors?

THE FACT IS CORROSIVE ENVIRONMENTS REQUIRE GREASE TO

PREVENT DOWN TIME.

The Dietrich Conical Blade Rotary Injector takes a dual approach to virtually eliminate

bearing failure.

All 3 rotating shafts have cup washers to protect all bearing seals.

However, no cup washer is 100% effective at keeping liquid out of the seal area.

It is the combination of a cup washer and a grease barrier

that ensures no liquid gets near the bearing seals.

With this design, no daily grease is required. Grease weekly and after clean up at the end of

season. This virtually avoids bearing failures. Everyone will agree a little time spent weekly

adding several shots of grease is a wonderful trade off to prevent down time and costly

bearing repairs.

Customers with “no grease” units say even 1 bearing failure during the season creates a real

dilemma. Do I replace all the bearings and seals before next season? Costly and time

consuming! Will several more bearings fail during the next season?

Some manufacturers use synthetic material for assembly pivot and closing blade pivot points.

Synthetic material is hard material but corrosive liquid will still seep into the synthetic material

area. By the next season, due to rust, the rough corroded steel surface will quickly grind

through the synthetic material leaving steel grinding on steel. John Deere experienced this

back in the 90’s when rain water created rust that caused synthetic material failure.

Greasing the 2 pivot points on the Dietrich Rotary Injector weekly will be time well spent.
