4.1 FERTILIZER DISTRIBUTION

4.1.1 SEED DISTRIBUTOR

The doser (Fig. 21) the most important part for seeder operation,
is located underneath the seed hopper.
It is driven by an electric motor connected to the tractor speed
sensor (See the Electrical Distribution Control Operation and
Maintenance Manual).
Thanks to a gearbox (A Fig. 21) it allows the distributor roller (B)
to operate with two gear ratios, by changing the position of the
red toothed wheel (C Fig. 21, 22, 23). In position «N» (Fig. 22),
the gear ratio is 1:1, as imposed by the pair of toothed wheels
Z19; when the wheel (C) is shifted to the «M» (Fig. 23) position,
the distributor wheel halves the number of revolutions, as the
drive is then composed of the red drive wheel Z14 and the drawn
wheel Z28. When a dosing test, as described in chapter 4.1.2, is
performed, it may be observed that the quantity of product
distributed is halved (see Distribution Table) compared to the
test using ratio 1:1. The position «M» of the toothed wheel (C) is
necessary for the distribution of small seeds and quantities.
The screw rod (D) enables the degree to which the gate opens
(F, Fig. 21) to be adjusted depending on the value of the graduated
scale, calculated using the table and the distribution test (chapter
4.1.2). The reference element for setting the gate valve opening
is point A (Fig. 25).
Caution: danger hazard for doser: Set a lower quantity of product
only when the doser is rotating or when the hopper is empty.
The locking spring (E Fig. 21, 24) enables the opening range of
the gate to be modified which, in turn, modifies the capacity of the
dosing roller at the same time. The position «E1» (Fig. 24) enables
the gate to be opened on a graduated scale, ranging from 0 to
110, with maximum capacity of the dosing roller; in the «E2»
position, on the other hand, there is a gate opening range of 0 to
25 and the capacity of the roller is reduced. It is important always
to remember to close the gate completely (0 on the graduated
scale) in order to invert the position of the locking spring (E).
Caution: danger hazard for doser: Set a lower quantity of product
only when the doser is rotating or when the hopper is empty.
When correctly placing the locking spring a click will be heard
indicating that the operation has been completed successfully.
