Note:
Hydraulic reservoir can be pressurized to up
to 5 psi to speed this process.
8. If either drive wheel still does not rotate, stop and
repeat steps 4 and 5 on the respective pump. If
wheels rotate slowly, the system may prime after
additional running. Recheck hydraulic fluid level.
9. Allow unit to run several minutes after the charge
pumps are primed with drive system in the full speed
position.
10. Check the hydro control linkage adjustment. Refer
to Adjusting the Hydro Control Linkages.
Checking the Hydraulic Lines
After every 100 operating hours, check hydraulic
lines and hoses for leaks, loose fittings, kinked lines,
loose mounting supports, wear, weather and chemical
deterioration. Make necessary repairs before operating.
Note:
Keep areas around hydraulic system clean from
grass and debris build up.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
•
If hydraulic fluid is injected into the skin
it must be surgically removed within a few
hours by a doctor familiar with this type of
injury. Gangrene may result if this is not
done.
•
Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
•
Use cardboard or paper to find hydraulic
leaks.
•
Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
•
Make sure all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.

Maintenance
Servicing the Cutting Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement, you
may want to keep extra blades on hand.
A worn or damaged blade can break, and a
piece of the blade could be thrown into the
operator’s or bystander’s area, resulting in
serious personal injury or death.
•
Inspect the blade periodically for wear or
damage.
•
Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control bail and set the parking brake. Turn the ignition
key to off. Remove the key and disconnect the spark
plug wire(s) from the spark plug(s).
Inspecting the Blades
Inspect the blades every 8 hours.
1. Inspect the cutting edges (Figure 55). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
