HYDRAULICS:
The hydraulic system on your Progressive mower is a simple
cylinder system used to raise and lower the cutting decks into
position. Each cylinder contains a .035 diameter restrictor
orifice, which is located on the rod end to slow the speed of
travel.
Restrictor Orifice
When reconnecting the quick disconnects to the tractor, be sure
that both ends are clean. Dirt in the hydraulic system can block
the orifice in the line throttle valve or even score the cylinder
tubes.
Hydraulic fluid escaping under pressure has enough force to
penetrate the skin. Seek medical attention at once if injured
by escaping fluid. 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.
If crimp-on hose ends are ever changed, be sure they are
compatible with the hose, to provide the proper crimping
pressure.
