Speed Control Linkage Adjustment

WARNING

Engine must be running and drive wheels must be turning so motion control adjustment can be performed. Contact with moving parts or hot surfaces may cause personal injury.

Keep fingers, hands, and clothing clear of rotating components and hot surfaces.

CAUTION

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

Adjust steering levers

1.Stop engine and wait for all moving parts to stop.

2.Pull the speed control lever completely back to the neutral position. The two steering levers should be straight up and down (vertical). If necessary, adjust steering levers by changing the length of the link between the speed control lever and the control arm on the end of the steering control shaft (see Figure 16).
