Adjusting the Mower Deck
Leveling Deck
Adjust the deck while the mower is on a level
surface. Make sure the tires are inated to the
correct pressure. See Tire Pressures in this
section. If tires are under or over inated, 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 oor 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 the bolt up until the two side
to side measurements are equal. Retain
measurement.
3. Turn the two 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 1/8" to 3/8" (3.175 mm -
9.525 mm) higher in the rear than the front
blade tips.
4. Conrm measurements once again. The
blade tip height must be equal side to side.
In the rear, the blade tips must be 1/8" to 3/8"
(3.175 mm - 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.
Pump Belt
The belts are not adjustable and need to be
replaced if they begin to slip from wear. Park the
mower on a level surface. Engage the park brake.
1. Remove the deck belt.
2. Remove clutch stop to access the belt.
3. Disconnect clutch wire.
4. With a 1/2" breaker bar and using the square
opening in the idler arm, shift the arm to
create slack in the belt.
5. Remove belt from the engine and pump
pulleys.
Reinstallation
1. Wrap the belt around the engine pulley and
then around the left pump pulley.
2. Route the belt around the inside of the idler
pulley.
3. With a 1/2" breaker bar and using the square
opening in the idler arm, shift the arm to
create slack in the belt.
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.
6. Check the belt tension. To tighten the
belt, turn the nut on the idler eyebolt. The
recommended belt tension is 27 lb.
