4.1NEUTRAL POSITION & TRACKING ADJUSTMENTS The joystick controls the movement and stopping of the machine. Move the joystick to the center or neutral position to stop machine. IMPORTANT: Always return the joystick with hand assistance to the neutral position. If machine does not come to a complete stop or has any movement when joystick is moved to the neutral position, adjustment must be made. It is recommended that these adjustments be made by an authorized SNAPPER dealer.
4.1.1. NEUTRAL POSITION
1.Turn key to the ”OFF” position.
2.Raise both rear wheels off the ground. Wheels should be high enough to rotate freely. Machine should also be high enough to view the hydro pumps that are located underneath the main case. Secure the machine with safety blocks.
3.Turn key to start position and start machine. Move engine speed control to “FAST” position.
4.Disengage parking brake. Both rear wheels should not have any movement, not rotating. If wheels are not rotating, no adjustment is necessary.
5.If wheel or wheels are rotating, the hydro pumps will have to be adjusted until neutral position is found.
6.NOTE: Neutral positioning brackets are located in the rear of the right side hydro pump (Shown in Illustration) and in the front of the left hydro pump. Locate the neutral positioning brackets on the hydro pumps. See Figure 4.1. IMPORTANT: It is necessary to disconnect the rear chain deck hangers and lower the rear of the deck to gain access to adjust left hydro pump.
7.Loosen the nuts that secure the brackets. Insert a small screwdriver all the way into both of the brackets. See Figure 4.1 Move screwdriver up or down to establish the neutral position and until the wheel stops moving. The outside bracket will be the only one that moves. Retighten nuts securely. Repeat procedure for other hydro pump. After adjustment, turn key to the “OFF” position. Reconnect the rear deck hanger chains to main case to secure deck. Return machine back to its wheels.
