Mower Maintenance
Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2. Shut off the machine and remove the key.
3. Raise the machine off the ground so that you
can access beneath it. Support the machine
using jackstands.
WARNING
Mechanical or hydraulic jacks may fail to
support the machine and cause serious
injury.
Use jack stands when supporting the
machine.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 28 ).
2. If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Sharpening the
Blades (page 29) .
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 28 ).

Checking for Bent Blades
Note:
The machine must be on a level surface for
the following procedure.
1. Raise the mower deck to the highest
height-of-cut position.
2. While wearing thickly padded gloves, or other
adequate hand protection, slowly rotate the
blade into a position that allows you to measure
the distance between the cutting edge and the
level surface the machine is on (
Figure 29 ).

the opposing cutting edge is now in the same
position (
