Loosen the ledger knife bolts and adjust it inward. Snug the
bolts by hand.
2.
Turn the rotor around so that one of the rotor blades is
directly in line with the ledger knife.
3.
Tap the ledger knife inward toward the rotor blade. Use
the clearance setting gauge to set clearance between the
two. If one is not available, set the clearance to 1/32–1/16"
(1 – 1-1/2 mm).
4.
Tighten the bolts to
33 lbf•ft (45 N•m)

corners of the blade have rounded over, remove the blade to
sharpen it.

7.9 Chop Block
Observe chop block function at each use. Sharpen or rotate
every 50 hours of operation.
The chop block is bolted in at the bottom of the upper rotor
housing. Its purpose is to help break material into smaller pieces
and turn it into mulch as the shredder knives pass when the
rotor is turning.
Inspect the chop block for damage such as gouges, or bent,
missing teeth. A damaged chop block should be replaced. If
teeth are showing wear, the chop block can be turned around
and installed the other way.
