GEARBOX
picture 10 The T25, T30 tillers are equipped with a gearbox and it is
possible to change the rotor speed independently from
the speed of the tractor’s PTO.
High speed improves the soil working, but rotating parts
wear more quickly.
To change the speed on the T25, T30 tillers, remove the
cover A (picture 10) of the box and invert the gears B
and C at the inner side; it is possible to obtain other two
speeds by replacing the fixed gears with the ones placed
on the cover.
For the gearbox speed refer to the labels on the machine.
Adjust the gearbox with the engine shut off, the power take
off disengaged, the parking brake engaged, and the
equipment resting on the ground.
CHAIN ADJUSTER
On the T5, T10 tillers are equipped with a chain drive, the chain adjustment is made during
assembly. Any adjustments when using the machines, must be carried out by an authorized dealer
or work shop.
START UP
After carrying out these adjustments, the equipment is ready for use. When at the working area, do
not start the power take off with the tiller in working position in the ground. Be sure to lift it by a
few centimetres using the tractor lift. Start the engine, engage the power take off, lower the
equipment to its working position and start.
ROAD TRANSPORT
With reference to road transport, follow local traffic regulations.
SHUT DOWN
The following activities are recommended if the tiller will not be used for a long period of time:
1 Clean and dry the equipment.
2 Inspect the equipment and replace the damaged or worn parts if necessary.
3 Tighten all the screws and nuts.
Lubricate and cover the machine with a tarpaulin and store it in a dry place.
