4.2.5Motion control linkage adjustment

WARNING

POTENTIAL HAZARD

Engine must be running and drive wheels must be turning so motion control adjustment can be performed.

WHAT CAN HAPPEN

Contact with moving parts or hot surfaces may cause personal injury.

HOW TO AVOID THE HAZARD

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

CAUTION

POTENTIAL HAZARD

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous.

WHAT CAN HAPPEN

The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

HOW TO AVOID THE HAZARD

DO NOT rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

Set neutral:

a)Remove the electrical connection from the seat safety switch, located directly in front of the seat switch assembly.

b)The neutral adjustment must be made with the drive wheels turning. Raise the frame and place on jack stands so that drive wheels can rotate freely.

Temporarily install a jumper wire across the terminals in the connector of the wiring harness.

c)Start the engine.

d)Run the unit at least 5 minutes with the drive levers at full forward speed to bring hydraulic system oil up to operating temperature.

e)To obtain the neutral position, adjust the left and right pump control rod linkages that connect the steering control to the pump control arms until the wheels stop, or creep slightly in reverse.

f)To adjust each linkage, loosen the jam nut next the ball joint at the upper end of the linkage rod assembly. Then rotate the assembly using a wrench to turn the double nuts on the assembly. See Figure 10.

g)Re-tighten the jam nut against the ball joint on each side.
