3.1 Adjusting the rear wheels
This section describe the procedure to change the
width of the rear tread.
WARNING
To avoid personal injury or death:
• Before jacking up the tractor, park it on a firm
and level ground and chock the rear wheels.
• Fix the front axle to keep it from pivoting.
• Select the jacks that withstand the machine
weight and set them up as shown in the
following figure.
(1) Jack point
1. Remove the bolts which mount the wheel rim and /
or disk.
2. Change the position of the rim and / or disk (right
and left) to the desired position.
3. Tighten the bolts.
IMPORTANT :
• Always attach the tires as shown in the
following figure.
• If you do not attach the rear wheel as the
following figure, transmission parts may be
damaged.
• Do not turn the rear discs to obtain the wider
tread.
• When re-fitting or adjusting a wheel, tighten
the bolts to the following torques.

BALLAST
WARNING
To avoid personal injury or death:
• You will need the additional ballast for
transporting the heavy implements. When the
implement is raised, drive slowly over rough
ground, regardless of how much ballast is used.
• Do not fill the front wheels with liquid to
maintain steering control.
1. Front ballast
Add weights if needed for stability (2WD and 4WD
models) and improve traction (4WD model). Heavy
pulling and heavy rear mounted implements tend to lift
the front wheels.
Add enough ballast to maintain the steering control and
prevent tip over.
Remove the weight when no longer needed.
IMPORTANT :
• Do not overload the tires.
• Add no more weight than indicated in the
following table.
