CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
NOTICE
Avoid low cutting heights. Striking the ground
with blades produces one of the most damaging
shock loads a mower can encounter. Allowing
blades to contact ground repeatedly will cause
damage to mower and drive.
1. Level mower from side to side. Check by
measuring from mower frame to the ground at
each deck rail.
2. Verify that the same amount of spacers are under
all caster arms.
3. Loosen cap screws that attach caster arm
assembly to deck.
4. Set mower on the ground.
5. Retighten cap screws. This equalizes the
clearance in the bolt holes.
6. Adjust front of mower level with or slightly lower
than the rear to obtain best mowing results. See
Figure 4.
7. Control cutting height by adjusting front and rear
caster wheels.
8. To raise rear of mower, move caster adjustment
spacers under rear caster arms. See Figure 6.
