MOWER DECK CUT HEIGHT
SETTING ADJUSTMENT
NOTE: Adjust side to side and front to rear
mower level before adjusting cut height.
1. Check air pressure on all four tires and
adjust to the correct pressure if necessary.
2. With foot pedal, set the cut height at the
notch marked 3.
3. Position left blade in the side to side posi-
tion and measure from the outside blade
tip to the level surface (refer to Fig. 19).
4. Position right blade in the side to side po-
sition and measure from the outside blade
tip to the level surface.
5. If the diff erence between both measure-
ments is greater than .125 inch, side to
side adjustment is necessary (see previ-
ous section).
6. If both measurements are between 2.875
inches and 3.125 inches, adjustment is
not necessary.
7. If both measurements are less than 2.875
inches or greater than 3.125 inch, adjust-
ment is necessary.
8. To adjust the cut height, place blocks
under both sides of the deck so there is
slack in the hanger chains. The actual cut
height is .5" above the sides of the deck.
9. Loosen the 2 bolts that secure the cut
height indicator.(Refer to page 20, Fig 5)
10. If the deck cut height needs raised, slide
the cut height indicator forward.
11. If the deck cut height needs lowered, slide
the cut height indicator back.
12. With blade cut height correct, securely
tighten the bolts.
13. Make sure foot pedal still engages in up-
per most position.
DECK BELT ADJUSTMENT
(Refer to Fig. 20)
The belt tension is set at the factory, but may
need adjustment after the fi rst hour of initial
use. Periodically belt should be checked for
proper tension, following the procedure be-
low:
1. Position the mower deck in the highest (4
inch) cut height setting.
2. Loosen the lock nut (A) and adjust the
draw nut (C) to change belt tension.
3. Increase belt tension by turning the draw
nut (C) clockwise and decrease belt
tension by turning the draw nut counter-
clockwise.
4. The idler spring (B) body length should
measure approximately 5.75" for proper
belt tension.
5. Tighten the lock nut (A) when the proper
belt tension is achieved.
