REPLACING/REPAIRING
Dozer Blade Cutting Edge
NOTE: The cutting edge of the dozer blade is re-
versible and needs to be replaced only when both
the top and bottom edges have worn.
Replace the dozer blade cutting edge as follows:
1. Remove the six (6) 5/16-NC hex nuts and
5/16 in. lock washers from the rear of the blade,
behind the cutting edge. Remove the six (6)
5/16-NC x 1 in. carriage bolts from the front cut-
ting edge.
2. If only one edge of the blade is dull or nicked,
rotate the blade 180 degrees. (The sharp edge
should now be at the bottom.) Reinstall the cut-
ting edge onto the dozer blade by reversing the
removal procedure.
3. If both edges are dull or nicked, remove the
cutting edge and install a new one by reversing
the removal procedure.
