Seed Distribution In The Seed Disc; Adjusting The Selector - Sola PROSEM K BASIC Series Starting Manual

ADJUSTMENTS

6.3 SEED DISTRIBUTION IN THE SEED DISC

The following adjustments affect directly on the quality of the seed dosing:
1. The selector's position in relation to the disc's holes. It is important to adjust the selector's
position depending on the type of seed to be distributed (see section 6.3.1. ADJUSTING THE
SELECTOR).
2. The seed ejector's position in relation to the disc's holes. In order to achieve a better seed
dosing, the metering box PROSEM is provided with a seed ejector slide (see 6.3.2 ADJUSTING
THE SEED EJECTOR).
3. The suction power needs to be adjusted to the weight of the seeds to be planted (see section
6.4 SUCTION SYSTEM – FAN).
IN ORDER TO GET AN EVEN AND PRECISE SOWING, IT IS RECOMMENDED TO NOT SURPASS 9
KM/H IN MACHINES PROSEM K AND 6 KM/H IN MACHINES PROSEM P.

6.3.1 ADJUSTING THE SELECTOR

The selector's lever can be adjusted from 0 to 10. When the lever is placed at a higher number,
the selector is being moved away from the hole and, therefore, the suction power is increased.
This causes a tendency towards the emergence of doubles. On the other side, when the lever
is placed at a lower number, the selector is being moved closer to the hole and, therefore, the
suction power is reduced. This causes a tendency towards the lack of seeds in the disc's hole.
Recommended selector's positions depending on the type of seed to be planted using stan-
dard seed discs (see section 3.6 Metering Box).
