Control Lever Neutral Adjustment
Before considering any adjustment, check tire air pressure and make certain hydraulic oil is at operating temperature. Unequal tire pressure will cause mower to drift to one side. Refer to “Tire Inflation Chart” on page 23 and page 48.
Adjustments for neutral position are made to the pump linkage rods located between the control lever and pump arms. The pump linkage rods are properly adjusted when control levers are in neutral position and drive wheels are not turning.

Refer to Figure 3-2:
If the mower creeps in neutral position, adjust pump linkage rods, located under the seat, as follows:
1.Disengage blade switch and turn ignition switch off.
2.Raise and block mower up to support drive wheels off the floor.
3.Position control levers in neutral position.
NOTE: Step 4 is not required but may be done if transaxle fan blades interfere with loosening the jam nuts on the pump linkage rods.
4. | Remove fan mounting hardware and transaxle fans if |
| the jam nuts under the fan are not accessible. |
5. | Loosen jam nuts at both ends of the pump linkage |
| rod by 5 or more full turns (approximately 1/4"). |
6. | Start engine and observe which way the wheels are |
| rotating. |
7. | If the wheel is rotating forward: |
| a. Rotate rod to shorten the steering control linkage |
| until the wheel comes to a stop. |
| b. Repeat for the opposite side if necessary. |
| c. When both wheels remain in neutral, turn ignition |

!WARNING
Make certain mower is secure when it is raised and placed on the jack stands. The jack stands should not allow the mower to move when the engine is running and the drive wheels are rotating. Use only certified jack stands.
!WARNING
The transaxle fan and pulley assemblies are turning while making adjustment to the pump linkage rods.
•Always turn off ignition switch before loosing and tightening the jamb nuts on the linkage rods.
•Always adjust the linkage rods at the flat surface located farthest from the fan and pulley assembly.
•Do not wear loose clothing that can become entangled in the fan and pulley assemblies.
•Keep hands and other extremities away from the fan and pulley assemblies while the engine is running.

9. | Reinstall transaxle fans if removed. Tighten fan |

10. | Start engine and test neutral adjustment again by |
| moving control levers forward and backward before |
| returning them to neutral position. The unit is ready |
| for operation if the tires do not rotate with the control |
| levers in neutral. |
11. | With ignition switch off, place control levers in park. |
| Remove support blocking and safely lower mower |
| wheels to the floor. |
IMPORTANT: It is important to always readjust the control lever stops after making adjustments to the pump linkage rods. See “Forward Stop Adjustment” on page 21 for adjusting procedures.
