OWNER SERVICE

A WARNING

■Lower mower to ground, turn tractor engine off and remove key before performing any mainte- nance.

■When completing a maintenance or service function, make sure all safety shields are in good condition and properly installed before placing mower in service.

A CAUTION

■Always use personal protection devices such as eye and ear protectors when performing mainte- nance functions.

BELT INSTALLATION

See Belt Installation in Assembly section on page 19.

BLADE SERVICING

Blades may be removed from the mower while it is still mounted on the tractor.

A WARNING

■If you suspend mower on tractor hydraulic sys- tem, be sure to install safety blocks. The tractor hydraulic system could fail, causing mower to fall and crush anything under it.

■Do not handle mower blades with bare hands. Careless or improper handling may result in seri- ous injury.

Inspect blades before each use to determine that they are mounted tightly and are in good condition. Replace any blade that is bent, excessively nicked, worn or has any other damage. Small nicks can be ground out when sharpening.

BLADE REMOVAL

See Figure 3. Install blade wrench over spindle pulley bolts to prevent spindle from rotating while removing bolt (10) which has left hand threads. Then remove special washer (9), sleeve (8), cup washers (7), shim

washer (6), blade (5), blade stop (4) and clutch disc (3). Shoulder washer (2) will not normally come off machine unless intentionally removed.

BLADE INSTALLATION

See Figure 3. Assemble shoulder washer (2) small end up (if removed). Install remaining parts in reverse order of disassembly. Ensure blade cutting edge is posi- tioned to lead in counter-clockwise rotation, as viewed from top of mower.

Shims should be added to blade installation to leave approximately 1/32" cup in cup washers when blade bolt is torqued to 170 lbs-ft.

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

This blade friction clutch disc allows the assembly to slip when hitting a solid object. If slippage occurs dur- ing normal mowing, it may be necessary to add an additional shim washer (6).

A WARNING

■Do not substitute any bolt for the special blade bolt. It is self-locking, meeting the non-loosening requirements for this application.

■Your dealer can supply Woods replacement blades. They are made of special steel alloys and subjected to rigid heat-treated and inspections requirements. Substitute blades may not meet these rigid specifications and may be dangerous.

BLADE SHARPENING

IMPORTANT

■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 mowing housing.

See Figure 4. Follow original sharpening pattern as shown in Figure 4. Do not sharpen blade to a razor edge, but leave a 1/32" to 1/16" blunt edge. Do not sharpen back side of blade.
