12 - Hoes replacement
The hoes replacement must be made disassembling the roller group and placing the machine on
the back side so that the hoes are parallel to the ground. Place the machine on a stable and safe
plane. When mounting the new hoes, be sure that the clamping nut fits well in its seat (Fig. 19 Ref.
B); It is necessary to use new nuts, bolts and washers each time the hoes are replaced. N.B. Use
always original steel bolts. In order to use the hoes as much as possible, the machine has on the
sides two extensions(Fig. 14 - Ref. D), this allows to work even if the hoes are worn out, the
consumption must not exceed the 2/3 of the hoe itself.

While replacing the hoes, wear protective gloves. If the maintenance is made on a raised
plane, always wear safety shoes.
All the maintenance work must be made with the tractor off and the key off.
If the tightening of the hoes screws is
made with pneumatic screwdrivers,
put on ear protections and protective
glasses.
