Before Operating

ADJUSTING HEIGHT-OF-CUT

The height-of-cut is adjustable from 25 to 102 mm in 13 mm incre-
ments by relocating four clevis pins in different hole locations to
prevent any operating of the cutting unit.
Note: All four pins should be in identical hole locations to prevent
any operating and cutting difficulties.

ADJUSTING THE ROLLERS

Note: If the cutting unit is to be used in 25 mm or 38 mm height-of-
cut setting, the internal and external rear cutting unit rollers must be
repositioned in the top bracket holes.
1. Remove the cotter pins securing the roller shafts to the under-
side of the deck (Fig. 2).
2. Slide the shafts out of lower bracket holes, align the rollers
with top holes and install the shafts.
3. Install the cotter pins to secure the assemblies.
