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 to be measure
into a position that allows effective measurement of the
distance between the cutting edge and the level surface
the machine is on (

Figure 61

).
