Ledger Blades:
Each machine is equipped with a ledger (stationary) blade that acts as a shear for the moving rotor
blades.
The ledger blade is designed with 4 usable corners. When the corner facing the rotor blade rounds
over, remove the blade and re-install with a different corner facing the rotor blade. It is recommended
that the clearance between the rotor and stationary blades be set and maintained at 1/32 to 1/16 " (.76
- 1.52 mm) to obtain the best performance.
1. Ensure the engine is off (ignition switch
is off and the fuel valve is closed).
2. Remove the 2 bolts that hold the ledger
blade to the ledger mount, remove the
blade.
3. Rotate the blade and replace or replace
with new or re-sharpened blade.
4. Hand tighten the bolts and set the clear-
ance between the ledger and rotor
blades at 1/32 - 1/16" (.76 - 1.52 mm). For
fast and easy setting, use our chipper
clearance setting gauge, available from
your dealer (see accessories)

Twig Breaker:
The Twig Breaker is a breaker tab located on side of the lower rotor housing. The discharge paddle
passes around the twig breaker and helps to break the material into smaller pieces and turn it into
mulch. Inspect the twig breaker for dam-
age such as gouges, a bent, or missing
tooth. A damaged twig breaker should
be replaced. If the tooth is showing wear,
remove and replace the twig breaker.
1. Ensure the engine is off (ignition switch
is off and the fuel valve is closed).
2. Remove the 2 bolts and nuts that hold
the twig breaker to the housing, remove
the twig breaker.
3. Reverse the steps to install the new
twig breaker.
