Preliminary operations
If the tractor is fitted with a front lift, refer to part: 09 20 To eliminate hydraulic pressure in the circuit.
– Position the tractor on flat stable ground.
– Stop the tractor.
– Apply the handbrake.
Warning: After removing the rear wheels, check the tractor is properly shimmed.
– Actuate all commands of the auxiliary valves in floating position.
