Adjusting the Control Handle
Neutral Position
If motion control levers do not align, or move easily into
the console notch, adjustment is required. Adjust each
lever, spring and rod separately.
Note: Motion control levers must be installed correctly.
See Installing the Motion Control Levers in the set up
instructions.
1. Disengage the PTO, move the motion control levers
to the neutral locked position and set the parking
brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Unlatch the seat and tilt the seat forward.
4. Begin with either the left or right motion control
lever.
5. Move the lever to the neutral position but not locked
(Figure 64).
6. Pull the lever back until the clevis pin (on arm
below pivot shaft) contacts the end of the slot (just
beginning to put pressure on the spring) (Figure 64).
7. Check where the control lever is relative to notch in
console (Figure 64). It should be centered allowing
lever to pivot outward to the neutral lock position.
