SUSPENSION HEIGHT ADJUSTMENT
If the rider tilts either side-to-side or front-to-rear, this
adjustment will level the frame with the ground.
Although this adjustment may not be necessary, it may
be required if additional weight (ie. a grass catcher) is
added to the frame or a drive tire is replaced.
NOTE: Perform this adjustment on a hard, level surface
such as a concrete floor. Making this adjustment will
affect the mower cutting height. For fine cutting height
adjustment, see Mower Deck Leveling Adjustment.
To level the frame, first measure the frame height:
1. The measurement to the top side of the front frame
rails, just behind the springs and shocks should be
20-5/8” (52,4cm) for each side (see arrow in Figure
29).
2. The measurement to the top of the rear frame rails,
at the widest point on the frame behind the drive
tires should be 21-3/8” (54,3cm) for each side (see
arrow in Figure 30).
3. Loosen the jam nuts and adjust the square-head
allen screw located above each spring.
4. After adjusting all four (4) springs, recheck the meas-
urements and adjust if necessary.

MOWING HEIGHT ADJUSTMENT
See Mower Deck Leveling Adjustment to ensure that the
actual cutting height is consistent with the cutting height
adjustment pin placement.
The cutting height adjustment pin (A, Figure 31) controls
the mower cutting height. The cutting height is
adjustable between 1-3/4” (4,4cm) and 5” (12,7cm) in
1/4” (0,64cm) increments.
Depress the deck lift foot pedal (B, Figure 31), placing
the majority of the force on the top edge of the pedal
until it locks into the “TRANSPORT” position.
Place the cutting height adjustment pin in the desired
cutting height. Depress the deck lift foot pedal, placing
the majority of the force on the bottom edge of the pedal
to release the pedal from the “TRANSPORT” position.
