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.
