Note:
This allows air to escape the hydraulic system
as you add hydraulic fluid.

Slowly add fluid to the hydraulic tank until it starts to
come out 1 of the vent plugs.
Important:
Use the fluid specified in
the Hydraulic System (page 46)
or equivalent.
Other fluids could cause system damage.
Important:
Monitor the level of fluid in the
hydraulic tank so that you do not overfill it.
13.
Tighten the vent plugs.
14.
Install the hydraulic-tank cap.
15.
Install the fuel tank.
16.
Start the engine and let it run for about 2 minutes to
purge air from the system.
17.
Shut off the engine and check for leaks.
Note:
If 1 or both wheels do not drive, refer to
Bleeding the Hydraulic System (page 48)
.
Bleeding the Hydraulic System
The traction system is self-bleeding, however, it may be
necessary to bleed the system if fluid is changed or after work
is performed on the system.
1.
Disengage the PTO and set the parking brake.
2.
Shut off the engine and wait for all moving parts to
stop before leaving the operating position.
3.
Raise the rear of the machine onto jack stands high
enough to raise the drive wheels off the ground.
4.
Start the engine and move the throttle control to the
idle position.
Note:
If the drive wheel does not rotate, it is possible
to assist the purging of the system by carefully rotating
the tire in the forward direction.
5.
Check the hydraulic fluid level as it drops, and add fluid
as required to maintain the proper level.
6.
Repeat this procedure for the opposite wheel.

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.
WARNING
A worn or damaged blade can break, and a piece
of the blade could be thrown at you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blades 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 blades and
set the parking brake. Turn the ignition key to O
FF
. Remove
the key, and disconnect the spark plug wires from the spark
plugs.
Inspecting the Blades
Service Interval:
Before each use or daily
1.
Inspect the cutting edges (
).
2.
If the edges are not sharp or have nicks, remove and
sharpen the blade; refer to
Sharpening the Blades (page
.
3.
Inspect the blades, especially in the curved area.
4.
If you notice any cracks, wear, or a slot forming in this
area, immediately install a new blade (
).
