Bush Hog Estate Series Neutral Adjustment, Control Lever Adjustment, To Avoid Possible Injury

5. CLEANING GRASS BUILD UP UNDER DECK

Depress the deck lift foot pedal and lock in position, then move the height adjustment pin to the 4-1/2” position.

Lift the front of the unit and support unit securely.

Clean out any grass build up from underside of deck and in deck discharge chute.

NEUTRAL ADJUSTMENT

1.Stop engine and remove ignition key.

2.Tilt seat forward.

3.Move the control lever rearward and release the control lever. This control lever should return to a position where the control lever can be swung outward and lock in the neutral outward position. This setting is fixed and not adjustable. If the handles do not return to neutral, contact a servicing dealer.

MOTION CONTROL NEUTRAL ADJUSTMENT

The steering has been factory adjusted to eliminate creeping when the control levers are in neutral posi- tion. However, should the mower begin to creep, adjustments can be made as outlined below. Before considering any adjustment, check the tire pressure and make certain hydraulic system oil is at operating temperature. Unequal tire pressure can cause the mower to drift to one side ( see recommended tire pressure).

1.Raise the drive wheels of the zero turn off the ground. Safely block the frame in this position so it is secure. This adjustment must be made with the drive wheels free to turn.

2.Remove the electrical connection from the seat switch and temporarily install a jumper wire across the terminals of the wiring harness.

3.Loosen the jamnuts on the vertical turnbuckles, which connect the lever control arms to the hydrostatic component control arms. Note: The nuts at the top of the turnbuckles have left- handed threads.

4.Start the engine. Release the parking brake and throttle up the engine to full throttle.

5.Observe which direction the wheels are rotating. If the wheels are rotating forward, rotate the verti- cal turnbuckle clockwise to shorten the steering control linkage until the wheel(s) come to a stop. Repeat for the opposite side if necessary.

(Note: The right hand linkage controls the right hydrostatic component and the left handle con- trols the left hydrostatic component)

6.If the wheels are rotating in reverse, then rotate the vertical turnbuckle counter-clockwise to lengthen the steering control linkage until the wheel(s) come to a stop. Repeat for the opposite side if necessary.

7.When both wheels remain in neutral, tighten the jam nuts to lock the vertical turnbuckle in place.

8.Test again by moving the control levers forward and backward before returning them to the neu- tral position. If the tires are in neutral, the unit is now ready for operation.

9.Shut the unit off. Remove the jumper wire from the wiring harness and replace the connectors into the seat switch. Never operate the mower unless all safety switches are operating properly.

CONTROL LEVER ADJUSTMENT

The control levers can be adjusted for operator com- fort. Loosen the hex head cap screws that attach the upper control lever to the lower control lever. The upper control lever can be pivoted to fit the operator’s personal preference. The control levers should be adjusted so they align with each other when in the neutral position. The upper levers can also be adjusted vertically for operator comfort. Note: The upper control levers were shipped in the highest position from the factory to allow for optional seats with armrests. If your unit does not have seat armrests, and you would prefer a lower height, then remove the hex head screws from each upper han- dle and lower to the lower position. Reinstall hard- ware and securely tighten.
