Checking the Hydraulic Lines
and Hoses
Service Interval: Before each use or daily
Inspect the hydraulic lines and hoses daily for
leaks, kinked lines, loose mounting supports, wear,
loose fittings, weather deterioration, and chemical
deterioration. Make all necessary repairs before
operating.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your 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.
• Seek immediate medical attention if fluid is
injected into skin.
Cutting Unit Maintenance
Backlapping the Cutting Units
WARNING
Contact with the reels or other moving parts can
result in personal injury.
• Keep fingers, hands, and clothing away from the
reels or other moving parts.
• Never attempt to turn the reels by hand or foot
while the engine is running.
Note: When backlapping, the front units all operate
together, and the rear units operate together.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brake, and move the PTO switch to OFF position.
2. Unlock and raise the hood to expose the controls.
3. Make initial reel to bedknife adjustments appropriate
for backlapping on all cutting units which are to
be backlapped; refer to the cutting unit Operator's
Manual.
4. Select either front, rear or both backlap levers to
determine which units to backlap (Figure 83).
5. Start the engine and run at low idle speed.
DANGER
Changing the engine speed while backlapping
may cause the reels to stall.
• Never change the engine speed while
backlapping.
• Only backlap at low idle engine speed.
DANGER
To avoid personal injury, be certain that you are
clear of the cutting units before proceeding.
6. With the Mow Speed Limiter in the mow position,
move the PTO switch to the ON position. Press the
Lift Switch to start the backlapping operation on the
designated reels.
7. Apply lapping compound with a long handle brush.
Never use a short handled brush.
