motor. Fluid by-passes the front wheel motor in the reverse direction because of
the check valve inside the front motor. The front wheel does not provide traction
in the reverse direction. Hydraulic fluid is continuously pumped through the
closed loop traction circuit as long as the traction pedal is pressed rearward.
The traction pump includes a relief valve (reverse direction) that limits reverse
traction circuit pressure to 22,063 kPa (3200 psi) bar).
The charge circuit functions the same in reverse as it does in the forward
direction. The left rear wheel motor bleed valve and the remote mounted relief
valve does not function in the reverse direction.
