Mower Deck Adjustment (Side-To-Side
Levelness)
Before making deck leveling adjustments, check the tire
pressure. Front tires 12 PSI, rear tires 12 PSI. If tires are
properly inflated and mowing is still uneven, adjust side-to-
side deck levelness.
1. Place the Rider on a smooth level surface.
2. Turn the engine off and remove the key. Remove the
spark plug wire from the spark plug and secure the wire
away from the plug.
3. Place a piece of angle iron, pipe, or similar object under
the rear center of the deck.
4. Remove the rear hanger chains
(A, Figure 35)
and allow
rear center of the deck to rest on the angle iron.
5. Measure the distance from the blade tips to the floor. If
the measurement is within 1/8” from side-to-side, the
deck attitude is satisfactory. If difference from side-to-
side is greater than 1/8”, continue with adjustment.
6. Loosen the hardware
(A, Figure 34)
that retains the left
side of the blade pedal
(B)
.
7. Move the lift arm
(C)
up or down as required until the
blade tips are within 1/8” of each other.
8. Tighten the hardware loosened in Step 6. Recheck both
sides of the deck for correct levelness.
9. Readjust the rear hanger chain pivots
(B, Figure 35)
to
align with the holes in the support brackets
(D)
.
10. Remove the angle iron, pipe, or similar object, and pro-
ceed to check front to rear levelness.
Mower Deck Adjustment (Front-to-Rear
Levelness)
28” and 33” Decks
With the Rear Engine Rider on a smooth, level surface,
rotate the blade until the blade tips are at the front and rear
of the deck. Measure the distance from the blade tips to the
floor
(Figure 35)
. The distance should be the same, or the
rear 1/8” to 1/4” lower than the front. If the rear blade tip is
higher than the front, or is more than 1/4” lower than the
front, proceed with adjustment.
30” Decks
With the Rear Engine Rider on a smooth, level surface,
rotate the blade until the blade tips are at the front and rear
of the deck. Measure the distance from the blade tips to the
floor
(Figure 35)
. The distance should be the same, or the
rear 1/8” to 1/4” higher than the front. If the rear blade tip is
lower than the front, or is more than 1/4” higher than the
front, proceed with adjustment.
Adjustment
1. Remove the rear hanger chains
(A, Figure 35)
.
2. Turn each hanger pivot
(B)
the same number of rota-
tions on the eye-bolt to raise or lower the rear of the
deck.
3. Reinstall the rear hanger chains and measure the blade
tips again.
4. Repeat Steps 1 through 3 until proper levelness is
obtained.
Maintenance (Continued)
WARNING
DO NOT attempt any adjustments, maintenance, service or
repairs with the engine running. STOP engine. STOP blade.
Engage parking brake. Remove key. Remove spark plug
wire from spark plug and secure away from plug. Engine
