DOSING ROLLERS
- Large diameter to reduce the number of revolutions and avoid
fertilizer 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!
WARNING
Always use gloves: after calibration, the new dosing rollers
could have sharp edges that might injure the operator!
There are various types of wheels for a wide range of applications,
in three different product families (Fig. 17):
red : 5 elements, 8 chambers per wheel, (mod. G1000) (D,
Fig. 17) distribution of large quantity (of series);
green : 5 elements, 16 chambers per wheel, (mod. N500) (E,
Fig. 17) (optional);
yellow :5 elements, 32 chambers per wheel, (fine seeds dosing
roller) (mod. F25-125) (F, Fig. 17) (equipment).
IMPORTANT: use a suitable metering roller with the type of
distributed seeds.

metering roller transmission (Fig. 18).
