Steering angle adjustment
When using the narrowest tracks, the tires may touch the
tractor body when the steered wheels are at full lock and
the front axle is at maximum pivot position. To avoid this
problem, the steering angle can be adjusted by means of
screw (1) fig. 5.
To adjust the steering angle, proceed as follows:
• turn the wheels;
• adjust the protrusion (L) fig. 5 of screw (1) fig. 6 so that
the wheels cannot come into contact with the tractor
body;
• on termination of adjustment operations, secure the
screw (1) by means of the locknut (2) fig. 6.
Repeat the same operations for the opposite wheel.
NOTE: After adjusting the steering angle, make sure that
when the wheels are fully locked, there is at least a 20
(0.79 in) clearance between the tire or the mudguard and
the tractor body.
Front axle swing adjustment
If necessary, you can increase the swing of the axle.
With the nut (1) fitted internally as in the figure, the axle
has its minimum swing.
To increase the swing, proceed as follows:
• Unscrew the screw (2) and move the nut (1) outwards.
NOTE: The same adjustments must be performed on the
opposite side.
NOTICE: When you are in the situation of greatest axle
swing, adjust the steering angle so as to prevent the fully
steered wheels from interfering with the casing.
With the front lift fitted, keep the nut (1) fitted inside on the
least swing.
