Hydraulics - Progressive Turf Equipment Pro-Flex 120 Operators Manual And Parts Lists

HYDRAULICS

During your daily inspection repair all leaks before they create a major problem.
Relieve all pressure before working on, or disconnecting the line in the hydraulic
system.
The hydraulic system on the Pro-Flex 120 mower is a simple cylinder system
used to raise and lower the cutting decks into position. Each cylinder contains a
.040 diameter restrictor orifice, located on the butt end, to reduce the speed of
travel.
When reconnecting to the tractor, be sure that both connector ends are clean. Dirt
in the hydraulic system can block the orifice in the line throttle valve or cause
premature wear & failure of hydraulic components on the mower or tractor.
The quarter turn valve located on the hose end to the tractor is used to shut off the
hydraulic system to the wing cylinders. This will ensure that no oil returns from
the mower into the tractor during operation. It should be in the closed position
while operating or servicing the mower.
