Independent Link Suspension or 1500 MFWD Clamp On Dual Front Tire, Fender and Steering Stop Settings

Tractors equipped with Independent Link Suspension (ILS) or 1500 MFWD axle are approved for limited use of clamp on front dual wheels. Clamp on duals are limited to two tire sizes, 540/65R34 and 600/70R30. Tread spacings available are in the table below. When using clamp on duals, all tread positions must use steering stop position 3. Tool Box must be moved from factory installed location to alternate right-hand location. See your John Deere dealer for details.

IMPORTANT: Any variance from tread settings listed below may damage fuel tank and/or steps.

NOTE: To determine the mean setting, add tread spacing for inner tire (center to center) and tread spacing for outer tire (center to center). Divide by two.

The mean tread setting cannot exceed 2794 mm (110 in.).

Maximum ILS or 1500 MFWD static front axle weight, without liquid ballast or duals, is 10795 kg (23800 lb).

NOTE: Listed below are instruction to use the Inner Wheel Tread Spacing Table.

IMPORTANT: Do not drive tractors equipped with duals faster than 40 km/h (25 mph).

The first row under the heading identifies tread spacing in millimeters and inches.

Column one provides tire size.

The first number in column identifies an eight position rim is used. The first letter indicates which example to follow from the Eight Position Wheel Settings. The next number is the correct steering stop position. The last capital letter is the fender setting, taken from 1500 MFWD and Independent Link Suspension Fender Settings block in this OM. If there is a “w” in the fifth position, it indicates the setting is for wide fenders.
