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.
