Adjusting Rear Wheel Tread-Hydraulic Adjust 1829-2667 mm (72-105 In.) Wheel Spacing (If Equipped)

causym CAUTION: Do not modify machine to achieve a tread setting of less than 1828 mm (72 in.). Machine will be unstable and can tip, causing injury or death to you or someone else.

NOTE: Sprayer with narrow tread option is infinitely adjustable between 1829-2896 mm (72-114 in.). Refer to chart for row spacing-to-tread setting recommendations.

1. Using chart, find specific row spacing of field and read across to wheel tread setting. Rear tread setting should agree with front wheel positions.

NOTE: Visual indicators (A) at the rear of each step show rear tread width. Observe indicators while making tread width adjustments.

5. Start engine and drive forward 2-5 Km/h (1-3 mph).

IMPORTANT: DO NOT attempt to adjust both axles at the same time or exceed 2-5 Km/h (1-3 mph). Operate one switch until axle is completely extended/retracted and then adjust axle on opposite side.
