IMPORTANT:
Tires must have at least 25 mm (1 in.) clearance (A) with fenders. Clearance (B) between tires must be at least 1041 mm (41 in.), with tires equal distance from center line.
Clearance between tires must be at least 1179 mm (46.4 in.) for category IV hitch, 1036 mm (40.8 in.) for category IV N, and 1047 mm (41.2 in) for category III hitch, when no side sway is permitted on mounted implements. With sway allowed, check tire clearance before using equipment.
Shims from your John Deere Dealer will further reduce hitch side sway and lengthening lift links to maximum length will provide more clearance for "row cropping" at 762 mm (30 in.) treads.
IMPORTANT:
With dual tires, refer to following chart for minimum spacing between
|
tires (C). (See Using Radial and Bias-Ply Tires for more information.)
Steering stops may be required for some tread settings.
Extremely wide wheel spacings provide higher loads for axle bearings and shafts. Try to minimize overall tread width.
