4.6 DIFFERENTIAL LOCK
The tractor has a mechanical differential lock on both axles.
To lock the front differential, pull up lever n.8 fig.1. Push the lever down to
release the lock.
To lock the rear differential, the procedure will depend on the type of hydraulic lift
installed:
With a normal raise-lower lift: hold lever n.12 fig.1 up.
With a draft control lift, pull up link rod n.37 fig.1. The differential will be released
automatically when the lever is released.
Only use the differential lock with the creep gear range and reduce
engine revs ahead of time. Do not use the differential lock going
into or in curves. If the differential lock does not release, reduce engine
revs, stop the tractor and release the differential lock by turning the
steering wheel right and left.
