6.10.1 Toe-in adjustment
The toe-in on the main chassis wheels may need to be adjusted if abnormal tyre wear
is observed, even with the tyres set to the correct pressure.
Before checking or adjusting the toe-in, ensure that the machine is tracking correctly
behind the tractor.
Check measurements
A1
and
A2
between the main wheels. The measurements
should be taken at the wheel rim edges, front and rear, as shown. The toe-in is set
correctly when
A2
dimension is between 1.5 mm and 4.5 mm wider than
A1
dimension.
If adjustments are required, then the rear steering rods
C
must be altered.
1.
Loosen the locknuts
D
on each end (Note LH & RH threads).
2.
Rotate the steering rod
C
either clockwise or anti-clockwise.
3.
Adjust both rods in small increments until desired toe-in is achieved.
4.
Tighten all locknuts
D
ensuring
B1
=
B2
After adjusting the toe-in, ensure that the machine is tracking correctly behind the
tractor.
NOTE:
Ensure both steering rods are adjusted equally so that
B1
=
B2
.
