Traction Reverse - Toro Sand Pro 2020 Service Manual

Traction Reverse

The traction circuit operates essentially the same in re-
verse as it does in forward. However, there are a few dif-
ferences in operation.
When the traction pedal is pressed to the reverse posi-
tion, the linkage from the pedal positions the swash plate
in the traction pump so oil flows out of port A. Oil flow out
of port A goes to the wheel motors and turns them in the
reverse direction. On the SP 5020, the oil flow goes
through the left and right rear wheel motors first and then
through the front wheel motor. Oil flowing out of the
wheel motors returns to port B of the hydrostat and is
continuously pumped out of port A.
The right wheel motor does not bleed off any hydraulic
fluid for cooling of the closed loop circuit in the reverse
direction.
