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.
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death. Trying to
repair a damaged blade may result in discontinued
safety certification of the product.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2. Shut off the engine, 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 60 ).
2. If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Sharpening the
Blades (page 44) .
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 60 ).

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 61 ).
