Section 3: Adjustments
Upper Control Lever
IMPORTANT: Make sure lower control levers have
been adjusted before adjusting upper control levers.
See page 22 for lower control lever adjustments.
The upper control levers may be adjusted while in neutral
position for height, reach, and forward travel to fit the
operator's steering comfort zone.
Height Adjustment
Refer to Figure 3-3:
1.
Adjust upper control levers (#2) vertically by removing
bolts (#3), and hex flange locknuts (#4) that attach
upper levers to the lower steering arms (#1).
2. Reposition upper control levers in holes A, B & C to a
height that fits the operator's personal preference.
3. Reassemble bolts and hex flange locknuts in the
same order they were removed without tightening
them.
Reach Adjustment
Refer to Figure 3-3:
The upper control levers (#2) can be adjusted forward or
rearward to make steering more comfortable.
NOTE: Adjust seat to operate deck pedal
comfortably before making "Reach Adjustment".
See "Seat Adjustment" on page 21.
1.
Loosen hex flange locknuts (#4) and pivot upper
control levers (#2) forward or backward to fit
operator's personal reach preference.
2. Verify that the control levers align with each other
when in neutral and tighten hex flange locknuts (#4)
to the correct torque.
Forward Travel Adjustment
Refer to Figure 3-3:
"Reach Adjustment" instructions adjust the upper
control levers to be equally aligned while in neutral.
However, with this adjustment, the mower may want to
steer slightly to the right or left when pushing the levers
equally forward.
Make the following adjustments if you prefer to have the
upper control levers equally aligned while in forward
travel position instead of neutral position:
1.
While driving forward, make the necessary steering
correction required to make the unit go straight and
take careful notice of how the upper control levers are
positioned. (The distance one lever is ahead of the
other to make the mower travel straight.)
2. Stop the mower on a level surface, place control
levers in neutral, set park brake (ON), shut power off,
and remove switch key.

3. You can either adjust the trailing lever forward by the
distance it was trailing or adjust the leading lever
back by the distance it was leading.
a. Loosen hex flange locknuts (#4) on the side to be
adjusted.
b. Reposition the lever forward or backward by the
distance it was trailing or leading.
c. Retighten hex flange locknuts (#4) to the correct
torque.
Example:
If the right control lever is one inch ahead of the left
control lever, stop unit and adjust either the right
upper control lever back one inch or the left upper
control lever forward one inch.
