The Traction Unit Operator's Manual provides informa-
tion regarding the operation, general maintenance and
maintenance intervals for your Groundsmaster ma-

Towing Traction Unit

IMPORTANT: If towing limits are exceeded, severe
damage to the piston pump may occur.
If it becomes necessary to tow (or push) the machine,
tow (or push) in a forward direction only and at a
speed below 3 mph. The piston (traction) pump is
equipped with a by−pass valve that needs to be turned
o
90 for towing. See Operator's Manual for Towing Pro-
cedures.

Check Hydraulic Fluid

The Groundsmaster 4000−D hydraulic system is de-
signed to operate on anti−wear hydraulic fluid. The res-
ervoir holds about 8 gallons (30.3 liters) of hydraulic
fluid. Check level of hydraulic fluid daily. See Opera-
tor's Manual for fluid level checking procedure and oil
recommendations.
