Shifter Detent Adjustment

Maintenance

Transmission shifter detent can be adjusted by adjusting the setscrew on the back side of transmission located just behind the neutral start switch. Turn setscrew in (clockwise) to hold the transmission shifter more positively in each gear and to increase the force on the lever required to shift gears.

Turn setscrew out (counterclockwise) to decrease force on lever required to shift gears. Factory setting is to turn setscrew all the way in then back out 1 1/2 turns.

Important: Screwing setscrew in too far will prevent the transmission from shifting.

PTO Safety Switch

Adjustment

1.Stop engine and wait for all moving parts to stop. Engage parking brake. Remove key or spark plug wire(s).

2.With the blades disengaged and the bellcrank touching the engine deck, adjust the blade safety switch (if needed) until the bellcrank depresses the plunger by 1/4 inch (.64 cm).

3.Be sure the bellcrank does not contact the switch body to prevent damage to the switch.

4.Retighten switch mounting hardware.

Handle Height Adjustment

The handle can be pivoted to allow positioning in one of the three holes allowing various adjustments for operator comfort (see Figure 26).

To adjust the handle height:

1.Remove the bottom mounting hardware on each side of the handle.

2.Pivot the handle to one of the three positions.

3.Re-install hardware and tighten.

Important: If the handle height position is changed, it will be necessary to readjust the drive and brake linkage (see Check Brake and Wheel Drive Linkage Adjustment section in Operation.)

Wheel Drive Spring Tension Adjustment

It may be necessary to increase wheel drive belt tension under certain operating conditions such as, wet grass, hilly terrain, or while pulling a sulky.

1.Stop engine and wait for all moving parts to stop. Engage parking brake. Remove key or spark plug wire(s).

2.Disengage neutral lock/park brake latches and release drive levers to lower spring force.

3.Remove the 5/16-18 inch whizlock nut securing the adjustment bolt to the drive wheel shield. Locate bolt assembly in the desired position as follows:

•Position A-Normal Conditions

•Position B-More Severe

•Position C-Most Severe

Note: Lever force is lowest with bolt assembly in Position A and will increase in Positions B and C (see Figure 27).
