Maintenance Instructions

Mower Blades

Mower blades are removed and remounted as de-
scribed in Sharpen Mower Blades instructions (re-
fer to CHECKING/SERVICING in this section). Dur-
ing the course of sharpening and inspecting mower
blades, if there are any of the following conditions
of wear or damage, blades should be replaced
for reasons of safety and performance of the ma-
chine:
● An excessive amount of the flat section of the
blade has been ground away (removed) when the
blade is sharpened. Replace the blade when less
than a 3/4 in. (19 mm) flat section remains at the
blade tip.
● Examine ends of the blade carefully, especially
the intersection where the flat section of the blade
turns up to form the "wing tip" (refer to CHECKING/
SERVICING for Mower Blade Profile for Sharpen-
ing illustration in Sharpen Mower Blades instruc-
tions). Since sand and abrasive material can wear
metal away in this area, the blade should be re-
placed when metal thickness has worn to
1/16 in. (1.6 mm) or less.
When blades are operated over sandy
soil, and if blades are allowed to wear, a
"slot" may be worn into the wing tip of
blade. Eventually a piece of the blade
may break off creating a serious potential
for injury or damage.
● Check the blades for straightness by marking
blade tip position inside the deck housing and then
rotating the opposite end of the blade to the same
position and comparing. If the difference in blade tip
track is more than 1/8 in. (3 mm), the blade is bent
and should be replaced.
● Inspect the blade surface, especially in formed
areas, for cracks. Replace the blade if any cracks
are found.

WARNING
DO NOT try to straighten a blade that is
bent. NEVER weld a broken or cracked
blade. ALWAYS replace with a new blade
to assure safety.
Reinstall the blades as described in Sharpen Mow-
er Blades instruction in this section. If blades are
replaced, always use Walker original equipment

guaranteed, they could be dangerous.
