Checking the
track
If the machine rolls at an offset angle to the tractor when driving a
straight line, the directional stability must be re-adjusted.
The steering is preset at the factory. If the factory setting needs to be
modified, the lock nut must be used to secure the steering rod from
being twisted.
Check the tracking as follows:
Switch off the tractor and secure it.
Check the values in accordance with the tables.
The track at the rear sides of the tyres must be 3 mm wider than the
track at the front sides of the tyres.
Deviating dimensions for machines with serial numbers 2501-2550:
