Hydraulic Plumbing For Pump
If speed increaser/pump is mounted on the cutter,
Refer to Figure 3-1:
If speed increaser/pump is mounted to the tractor
power take-off shaft, Refer to Figure 3-2:
IMPORTANT:
Before engaging tractor power take-
off, make sure reservoir is full of hydraulic oil, shut-
off valve is fully open, and speed increaser/pump
hydraulic plumbing is configured correctly.
The hydraulic motor on the deck is powered by a tractor
driven power take-off speed increaser/pump receiving
fluid from the 35 gallon reservoir.
If cutter blades stall, an overpressure relief valve opens to
return oil to the reservoir. All returned oil is filtered of
particulates before dumping into the reservoir. Case
drain oil is not filtered.
