SLOWING AND STOPPING TRACTOR

NOTE
There are four ways to slow the tractor: release accelerator, apply
engine retarder, manually downshift transmission, or apply service
brake. The service brake may be applied on its own or in conjunction
with the engine retarder and/or transmission downshifting.
The recommended technique for stopping an ABS equipped tractor in
a typical full-braking emergency is to press the brake pedal down as
firmly as possible and, where appropriate, to steer around
obstructions.
The primary difference in applying the service brake with ABS is to
keep foot firmly planted on the brake pedal when stopping, rather
than manually pumping the brakes, to prevent wheel lockup and
subsequent skidding.
1.
Release accelerator (figure 4, item 1) and allow reduction in engine RPM and automatic downshifting of
transmission to help slow tractor.
2.
Depress engine retarder control pedal (figure 4, item 3) where conditions permit. Refer to
TM 9-2320-283-10.
Figure 4. Accelerator and Brake Retarder.
3.
Manually downshift transmission by placing transmission control lever (figure 5, item 1) in a lower gear
range where conditions permit. Refer to TM 9-2320-283-10.
