DUAL REAR WHEELS
WARNING
Tractor wheels are very heavy. Handle with care
and make sure, when stored, that they cannot fall
and cause injury.
NOTE: Dual rear wheels may only be installed on
tractors with 2845 mm (112 ″ ) or 3048 mm (120 ″ ) rear
axles.
The outer wheel track spacing can be adjusted to a
maximum of 3251 mm (128″) and the inner wheel to
a minimum of 1524 mm (60″). Position the wheels on
the axle to achieve the desired track spacing. See
“Outer Wheels” and “Inner Wheels” in this section.
Dual rear wheels may be installed on tractors
equipped with the 2845 mm (112″) or 3048 mm
(120″) axle.

Outer Wheels
The outer wheels, 1, are pressed steel wheels. They
are bolted to extension hubs, 2, that are clamped to
the axle shafts using wedges, 3, in the same manner
as Model 2145 pressed steel single wheels.
The hub to wedge attaching hardware can be
installed in either of two positions to make removal
easier depending on wheel spacing.
Option 1

the wedge side as shown in 4, Figures 185 and 186.
Torque bolts to 391 N·m (290 ft.-lbs.).
Option 2
Install four 178 mm (7″) long wedge to hub bolts from
the hub side as shown in 5, Figures 185 and 186.
Torque bolts to 391 N·m (290 ft.-lbs.).
IMPORTANT: These 178 mm (7 ″ ) long bolts are
included in the optional dual wheel kit available
