MAINTENANCE
REPLACING BLADES
Follow these steps when replacing blades. The WC68 wood chipper uses four (4) reversible
hardened steel blades. Each blade is 8.62 X 2.72 X 5/16” (219 X 69 X 8 mm) in size.
1. If installed, disconnect the PTO shaft from the tractor for safety.
2. Open the upper flywheel housing using a 24 mm socket/wrench by removing the M16 X
40 mm bolt and flat washer securing the upper and lower housings together.
3. With the flywheel exposed, manually rotate it so that one of the four (4) locking holes in
the flywheel (near the front of the blade) approximately lines up with the flywheel lock pin
at the rear of the housing. Remove the small locking pin from the flywheel lock pin and
flip the flywheel lock pin around 180°, passing it through the housing and into the locking
hole in the flywheel. Reinstall the smaller locking pin to the flywheel lock pin.
