Upper Control Lever
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 3-6:
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 3-6:
The upper control levers (#2) can be adjusted forward or
rearward to make steering more comfortable.
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 3-6:
“Reach Adjustment” instructions adjust 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
upper control levers equally aligned while in forward
travel position instead of neutral position:
1. While driving forward, make 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 mower on a level surface, place control levers in
neutral, set park brake (ON), shut power off and
remove switch key.
IMPORTANT: Make sure lower control levers have
been adjusted before adjusting upper control levers.
See page 26 for lower control lever adjustments.
NOTE: Adjust seat reach to operate the deck pedal
comfortably before making “Reach Adjustment” to
the upper control levers. See “Seat Reach
Adjustment” on page 25 for instructions.

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 either adjust the right
upper control lever back one inch or adjust the left
upper control lever forward one inch.
