Seat Adjustment Knob (Suspension/Ride Comfort):

The

seat adjustment knob (B) adjusts the suspension of the seat

(ride comfort). Turn the adjustment knob until the display

scale has a reading that matches the weight of the operator.

Ground Speed Control Lever Adjustment

The control levers can be adjusted in three ways. The

alignment of the control levers, the placement of the control

levers (how close the ends are to one another), and the

height of the control levers can be adjusted.

To Adjust the Control Lever Alignment

Loosen the mount bolts (A, Figure 42) and pivot the control

lever(s) (C) to align with each other.

To Adjust the Control Lever Placement

Loosen the jam nuts and adjust the placement bolt (B) in or

out to properly adjust the control lever end spacing.

To Adjust the Control Lever Height

Remove the mounting hardware and position the control lever

either up or down from its original position. You will need to

adjust the control lever alignment as described above.

Speed Balancing Adjustment

If the unit drifts to the right or left when the ground speed

control levers are in the maximum forward position, the top

speed of each of these control levers can be balanced by

turning the adjustment bolt(s) (A, Figure 43). Only adjust the

speed of the wheel that is traveling faster.

To Reduce the Speed of the Faster Wheel

1. Loosen the securing nut (B).
2. Turn the top speed adjustment bolt

counter-clockwise

reduce the speed.

3. Tighten the securing nut when adjustment is complete.

WARNING

Unsafe Operation Hazard.

DO NOT adjust the unit for a faster overall speed forward or

reverse than it was designed for.

Checking Tire Pressures

Tire pressure should be checked periodically, and maintained

at the levels shown in the Specifications chart. Note that

these pressures may differ slightly from the "Max Inflation"

stamped on the side-wall of the tires. The pressures shown

provide proper traction and extend tire life.

Cutting Height Adjustment

The cutting height adjustment pin (A, Figure 44) controls

the mower's cutting height. The cutting height is adjustable
