circuit temperature constant. If necessary, have your retailer install an oil radiator.
5.3.
DISTRIBUTION
The doser, the main organ for seeder operation, is positioned
under the seed tank and is moved by the sowing wheel by
way of mechanical transmission with chain and cardan shaft.
On the basis of the setting fixed using the command B, the
doser star wheel A distributes the correct quantity of seeds to
the “Venturi” type ejector C.
The air flow generated by the fan D and regulated by the
throttle valve E transports the seed to the head of the
distributor at the end of the “Venturi” tube. From here the
seeds are taken to the coulters and then sown. The doser
can work seeds of sizes from 1 to 10 mm, and the following
can mainly be sown:
•
Cereals: wheat, barley, oats, rye, triticale, sorghum, rice
•
Large seeds: corn, peas, beans, soy
•
Minute seeds: grass, clover, colza

UNCOUPLING THE SEEDER
Uncoupling the seeder from the tractor is a very dangerous operation. Be very careful to follow the instructions
when carrying out this operation.
To uncouple the seeder correctly it is important to work on a horizontal surface and proceed as follows:
•
Remove the cardan joint from the rear power takeoff of the harrow
•
Disconnect all the hydraulic or electric connections that supply the seeder
•
Raise the harrow to a height that allows the four supplied legs to be inserted under the seeder frame. Insert the legs and
remove the connecting screw D that unites the seeder frame to the fast coupler (see section 4.3)
•
Position the support legs under the seed bar.
•
Unhook the seeder bar using the parallelogram tie rods that are positioned on the rear roller.
•
Lower the harrow slowly and, when you are sure that uncoupling is complete, it will be possible to move away with the
rotating harrow.
