Reverse Direction (continued)

Groundsmaster 360

16225SL Rev C

In the reverse direction, the pilot directional valves PD1 and PD2 in the traction

manifold assembly are not shifted. This disables the check valves (CV1 and

CV2) ensuring optimal 4-wheel drive traction while in reverse.

Because the vehicle speed in the reverse direction is typically reduced, there

is less hydraulic flow through the traction circuit. This lower flow results in less

circuit flow change necessary through the traction manifold assembly and

balancing fluid lines.
