Checking the Hydraulic Lines
Service Interval:
Every 100 hours
Check hydraulic hoses and hoses for leaks, loose fittings,
kinked hoses, loose mounting supports, wear, general
weathering, and chemical deterioration. Make any necessary
repairs before operating.
Note:
Keep areas around the hydraulic system clean from
grass and debris buildup.
Note:
Extended operating time at high temperatures in a hot
climate may lead to deterioration of hoses and seals. Inspect
more frequently in a hot climate, and change the hydraulic
oil and filter more frequently.

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 into the operator's
or bystanders’ area, 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 off. 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 (Figure 77).
2.
If the edges are not sharp or have nicks, remove and
sharpen the blade; refer to Sharpening the Blades (page
54).
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 (Figure 77).
