Height Of Cut Adjustments - Textron Bob-Cat Operator's Manual

HYDRO
MIDSIZE
The cutting height is determined by the position of the
blades in relation to the wheels. Variation of this height
is made at four points:
1. Casters
2. Cutter deck attachment
3. Blade spacers (side discharge only)
4. Wheel motors.
See the Height of Cut charts for setting combinations.
Make any adjustments to set height of cut with the
engine shut off, spark plug wire disconnected and
mower drive disengaged
1. CASTER WHEELS
a. Remove the quick pin (A) from the top of the caster
wheel pivot spindle.
b. Place adjustment spacers below the wheel sup-
port bracket and replace quick pin.
NOTE - For the Versadeck when set up with mulching
blades, height of cut adjustments are made only with
casters, cutter deck attachment and wheel motor
position. DO NOT put spacers between the blade and
spindle for the Versadeck when mulching blades are
installed.

2. CUTTER BLADE SPACERS
(side discharge blades only)
a. Make sure spark plug wire is disconnected.
b. Remove nut (A), spacers and washer from the blade
bolt.
c. Withdraw the blade bolt from the bottom.
d. Place spacers (2 maximum) on the cutter spindle
bolt between the blade and spindle.
e. Replace the bolt, blade and spindle.
f. Place excess spacer(s) on the cutter spindle bolt
between the nut and conical washer, as shown
below. This washer must be against the pulley so
that the blade bolt clamps the top bearing inner
race between the pulley and the shaft. Improper
assembly can allow the shaft to spin in the bearing.
This is not covered under warranty if assembled
wrong.
g. Replace nut (A) and tighten to 70 ft-lbs.
