MAINTENANCE
4. While holding the idler back with the breaker
bar, wrap the belt around the right pump
pulley.
5. Replace and secure clutch stop. Reinstall the
deck belt.
V-belts
Check every 100 hours of operation. Check for
severe cracking and large nicks.
NOTE: The belt will show some small cracks in
normal operation.
Adjusting the Mower Deck
Leveling Deck
Adjust the deck while the mower is on a level
surface. Make sure the tires are inflated to
the correct pressure. See Tire Pressures in
Maintenance section. If tires are under or over
inflated, the deck cannot be properly adjusted.
Faulty mower deck adjustments will cause an
uneven mowing result.
Four bolts control the height and pitch of the
mower deck. Adjust the deck slightly higher in the
rear.
NOTE: To insure precision in the leveling
procedure, mower deck drive belt must be
installed prior to leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip
to align with the deck side-to-side.
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record this measurement.
Move to the opposite side; check that
measurement is the same. If adjustment is
required, loosen the locknut and adjust bolt
up until both side-to-side measurements are
equal. Retain measurement.
3. Turn both outer blades to align with the deck
front-to-rear. Reposition the rear mounting
bolts up or down until the rear blade tips are
positioned 3,175 mm to 9,525 mm higher in
the rear than the front blade tips.
4. Confirm measurements once again. The
blade tip height must be equal side-to-side.
In the rear, blade tips must be 3,175 mm to
9,525 mm higher than the front measurement.
In the front, blade tips must be equal from
side-to-side.
NOTE: This will place the mower deck in a
standard measurement position. Depending on
the type of grass being mowed or environmental
conditions, more adjustments may be required to
get the desired cut.
Caster Wheels
Check every 200 hours. Check that wheels rotate
freely.
To replace, remove nut and caster bolt. Pull the
wheel out of the fork. Install in reverse order.
Tighten caster bolt. Torque to 45 ft-lbs (61 Nm),
then back nut off a half turn.
NOTE: Tire must rotate freely but axle spacers
must not. If wheels do not rotate freely take the
unit to the dealer for service.
