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.

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 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 following procedure from Sharpen Mower Blades instructions in CHECK- ING/SERVICING in this section. If blades are re- placed, always use Walker original equipment blades to ensure safety and optimum performance. The quality and performance of replacement blades offered by other manufacturers cannot be guaranteed, they could be dangerous.

CAUTION

ALWAYS use genuine factory replace- ment parts. Substitute parts CAN result in product malfunction and possible in- jury to the operator.
