3.4 DOSER

The doser (Fig. 7) the most important part for distribution, is
located underneath the seed hopper.
It is driven by an electric motor connected to the tractor speed
sensor.
In that event, for the metering operation and the metering
adjustment, checking and tests, please refer to the relevant User
and Maintenance Booklet.
The volumetric distributing device, GRINTA, is essentially
composed of four elements for seeds distribution:
A) aluminium monobloc frame;
B) agitator element;
C) dosing rollers;
D) feeler pin.

MONOBLOC FRAME

The monobloc frame is made of aluminium and offers the following main advantages:
- realization of very high precision and high quality over time;
- resistance to the effects of UV rays or to the problems of harsh autside temperatures;
- high resistance to corrosion;
- quick simple maintenance: in a few minutes we can completely remove the components of the doser without fully unscrewing the
screws, using just one spanner.

AGITATOR ELEMENT

Guarantee of continuous feeding to the dosing rollers.
The agitator has a diameter of 85 mm and
consists of 4 elements (curved pins). If the
agitator is running too fast, its mixing effect
can be halved, by removing the two center
pins (B, Fig. 7).
The agitator can be disabled by simply
removing the drive belt.
- To disable the agitator, lift the round belt
above the edge of the drive pulley and, on
the opposite side, rotate the dosing roller
in the driving direction. The belt will come
off (Fig. 8).
- Simply leave the belt on the drive shaft
(Fig. 9).
(To fit the belt, see chapter on dosing roller)
DOSING ROLLERS (Fig. 10)
- Large diameter to reduce the number of revolutions and avoid seed load losses;
- High number of cells arranged in a steggered pattern to guarantee uninterrupted delivery;
Assembling and disassembling the dosing roller
All the dosing rollers are compact units constructed in a single block (except for the fine seeds dosing roller, yellow).
Never fit dosing rollers with screws loosening the handwheel! The radial precision of the wheels, which are calibrated after
assembly, could be damaged!
Always use gloves: after calibration, the new dosing rollers could have sharp edges that might injure the operator!
