Mower Blades
Mower blades are removed and remounted as
described in Sharpen Mower Blades on page
73. During 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 machine:
● An excessive amount of the at 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) at section
remains at the blade tip.
● Examine ends of the blade carefully, especially
the intersection where the at section of the
blade turns up to form the “wing tip” (refer to
the illustration Mower Blade Prole for
Sharpening on page 74 for location of the
wing tip and wear area). Since sand and abra-
sive material can wear metal away in this area,
the blade should be replaced when metal
thickness has worn to 1/16 in. (1.6 mm) or
less.
DANGER
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
o󰀨 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 di󰀨er-
ence 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 following procedure from
Sharpen Mower Blades on page 73. If blades
are replaced, always use Walker original equip-
ment blades to ensure safety and optimum perfor-
mance. The quality and performance of replace-
ment blades o󰀨ered by other manufacturers
cannot be guaranteed, they could be dangerous.
CAUTION
ALWAYS use genuine factory replacement
parts. Substitute parts CAN result in prod-
uct malfunction and possible injury to the
operator.
