Woods Equipment L306A-3, L59A-3 Owner Service, Sharpening, Removal and Installation, A Caution

Sharpening

NOTICE

■When sharpening blades, be sure to balance them. Unbalanced blades will cause excessive vibration which can damage blade spindle bear- ings. Vibration may also cause structural cracks in mower housing.

Figure 5. Blade Sharpening

Remove blades. Always sharpen both ends at the same time to maintain balance. Follow the original sharpening pattern. Do not sharpen blade to a razor edge. Leave from 1/32" to 1/16" blunt edge. Do not sharpen backside.

A CAUTION

■Your dealer can supply genuine replacement blades. Substitute blades may not meet original equipment specifications and may be dangerous.

Removal and Installation

Wedge a block of wood between blade and mower housing, or install blade wrench over spindle pulley bolts to prevent spindle from rotating while removing bolts. Loosen the Nylok blade bolt, which has left hand threads.

L59 Removal

Remove the bolt, two cup washers, flat washers and blade. The shoulder washer will not normally come off the machine unless intentionally removed.

L59 Installation

Install shoulder washer (if removed) small end up.

Position blade. Be sure cutting edge is positioned to lead in counter-clockwise rotation, as viewed from top of mower.

Install flat washer, cup washers and bolt. Torque bolt to 170 lbs-ft.

Excessive blade slippage can cause the cup washers to burn and lose their clamping force. If this happens, the cup washers must be replaced.
