Forward Stop Adjustment

The control lever stops are designed to do two things: First, and most important, they must keep the pumps from bottoming out internally. Second, the stops may be adjusted to help drive straight when the control levers are pushed forward against the stops.

Adjust Lever Stops to Protect Pumps

Refer to Figure 3-3:

This adjustment should be made first and must be made with mower engine NOT RUNNING. Check one side at a time to make sure each control lever is against the adjustable stop before the pump bottoms out internally.

1.Raise the seat up and gently and slowly move one of the control levers forward and feel if there is some resistance on the lever before the control lever hits the stop. If you sense the pump linkage rod is stopping forward motion before the control lever comes against the stop, then do the following:

a.Loosen the jam nut for that adjustable stop.

b.Turn stop (hex socket set screw) out until control lever is stopped by the set screw slightly before the pump linkage rod bottoms out.

c.When adjustment is correct, tighten jam nut.

2.Repeat step 1 for the other control lever.

Adjust Lever Stops to Drive Straight

NOTE: Variables such as oil temperature, pump efficiency, motor efficiency, tire pressure, etc., may effect the consistency to drive straight while pressing the control levers against the stops.

Refer to Figure 3-3:

1.Determine which drive tire is rotating too fast when both control levers are against the stops.

2.Stop the mower and loosen the jam nut on the side which is rotating too fast. Back the stop (set screw) out to stop the control lever sooner.

3.Tighten the jam nut on the stop and test again.

4.Repeat this procedure until unit drives straight.

Steering Dampener

Refer to Figure 3-4:

The steering dampeners, located under the seat, are incorporated into the unit to provide some resistance when control levers are moved forward or rearward and return levers to neutral when backing up.

Make sure steering dampeners are adjusted properly by moving control levers to the reverse position and releasing them. If control levers return to neutral position, they are working correctly. Adjust dampeners if they do not return to neutral. Adjusted as follows:

1.Place control lever in neutral position.

2.Adjust left dampener:

a.Loosen nut on the left rear ball stud.

b.Pull dampener spring housing, to the rear, past the point that the internal spring is engaged.

c.Release dampener spring housing and allow the internal spring to bring the housing back to neutral position.

d.Retighten left rear ball stud nut.

4.Check steering dampeners:

a.Move the control levers to reverse position and release. The control levers should return to neutral position.

b.Repeat steps 1 through 4 if control levers do not return to neutral position.
