• Never operate the tractor with a loose rim,
wheel or axle.
1. Adjusting wheels with bar type
axle
Rear tread width can be adjusted as shown with the
standard equipped tyres.
To change the tread width:
1. Clean the axle with a wire brush.
2. Keep the wheel whose tread will be readjusted
slightly above the floor.
3. There are 4 flange bolts. Remove the 2 diagonally
opposite to each other and loosen the other two.
4. Apply the removed 2 bolts into the jack bolt holes.
Tighten up these 2 bolts evenly and draw out the
tyre flange toward yourself.
5. Slide the wheel to a desired tread width. If the
retainer and the bar axle are stuck too hard to slide
the wheel, drive a wedge in the retainer's slot for
smooth motion.
6. Remove the jack bolts and fix the tire flange and
retainer with the bolts.
7. Use the same procedure for the other-side wheel.

NOTE :
• For easy tread
preferably dismount the rear wheel ballast to
lighten the total weight of the wheel.
• After readjusting to a new tread width, make
sure there is enough clearance between the
tyre and tyre fender, as well as between the
tyre and lower link.
IMPORTANT :
• Always attach wheels as shown in the
drawing.
• If not attached as illustrated, transmission
parts may be damaged.
• When re-fitting or adjusting a wheel, tighten
the bolts to the following torques then
recheck after driving the tractor 200 m
(200 yards) and
movement by 5 m (5 yards), and thereafter
according to service interval.
