arms are stopping the forward motion of the control arms, loosen the jam nut on the adjustable stop of the corresponding side and turn the stop (set screw) inward to stop the control levers slightly before the pump bottoms out. Lock in place when the adjustment is correct by
3. Do this for each side.
To adjust the stops for driving straight when control levers are against the stops during operation:
Determine which drive tire is rotating too fast when both control levers are against the stops. Then stop the mower and loosen the lock nut on the side which is rotating too fast and turn the stop (set screw) inward to stop the control lever sooner. Tighten the lock nut on the stop and test again. Repeat this procedure until unit drives straight.
NOTE: Since this is a hydrostatic drive, variables such as temperature of oil, efficiency of pumps and motors, tire pressure etc., may effect the consistency of the ability to rely on the stops to drive straight without the operator making minor steering adjustments with the control arms.
Reverse Spring Adjustment
Refer to Figure
Reverse Spring

Control Lever Stops

The reverse spring is designed to bring the control levers to the neutral position after they are released from the reverse position.
To adjust:
1. Make certain the control lever neutral adjustment is |

To keep the pumps from bottoming out internally use the following procedure:
1.To make the first adjustment the mower engine must NOT be running.
2.Check to make sure the control levers are against the stops before the pumps are bottomed out internally. To do this, gently and slowly move the control levers forward and feel if there is some resistance on the pump lever before the control levers hit the stops. Check one side at a time. If you sense that the pump
| correct. If not, refer to Steering Linkage section. |
2. | When control lever is in the reverse position the spring |
| should force the control lever to return to neutral after |
| the lever is released. |
3. | Adjust the top nylock nut on the spring linkage until the |
| control lever returns to the neutral position from the |
| reverse position properly. Tightening the nylock nut |
| will cause the control lever to travel forward less |
| before stopping. Loosening the nylock nut will allow |
| the control lever to travel farther forward. |
4. | Check the length of the reverse spring when the |
| control lever is in the neutral position. This dimension |
| should be 1 7/8”. If it is not, adjust the lower nylock nut |
| until the dimension is achieved. |
5. | Repeat for other side. |
