4.5.2 HITCHING/UNHITCHING THE HARROW UNITS

The hydraulic circuit of the machine is designed to automatically and sequentially hitch and unhitch the two harrows for road
transport, by operating two clamps with a control situated near the driving position.

4.5 TOOLS

The blades fitted on the implement are suitable for soil of a normal consistency. Check them daily to make sure that they are in a
good condition and not worn. If the blades should accidentally bend (or break) during work, they must be immediately replaced.
Make sure that the new blades are mounted in exactly the same positions as the old ones. If several blades must be replaced, it
is advisable to demount and remount them one at a time in order to avoid positioning errors. The sharp side of the blades must
point towards the direction in which the blade rotor turns.
Proceed in the following way to change the blades:
Park the tractor on a flat surface with the machine hitched, then raise the machine with the power lift;
Insert two strong bearing stands at the sides of the machine;
Lower the machine on to the stands, turn off the tractor engine and apply the parking brake.
The head of the bolts fixing the blades must be placed on the same part of the blade itself and the nut/double nut on the
blade-holder support. Comply with the driving torque values given in the table below. If blades must be changed, make sure
that the new ones are mounted in the same positions as the old ones.

the tractor and engage the parking brake. Wait until all moving parts have come to a complete standstill, then proceed with
the cleaning operations with the utmost care.
Blade replacement is a dangerous operation.
