4.3.2 Checks during Sowing
The following checks should be carried out during sowing, after each sown hectare:
1.
Ensure that the sowing units dispense seeds and they are not blocked.
2.
Check that the air conduit set is properly attached both upstream and downstream the dispenser. The
hoses leading from the manifold to the coulters should not have any bends or horizontal sections.
3.
Check correct connection of the turbine hydraulic conduits with the tractor distributor.
4.
Check visually that no seed hose is clogged.
5.
Ensure that the amount of seeds coming out of each sowing unit is identical.
6.
Check the sowing depth manually across the entire width of the machine.
7.
Ensure that the seed container tarpaulin is closed properly.
8.
Clean the grille at the turbine inlet regularly in order to avoid clogging, as this could lead to
contamination of the seed lines.
4.3. Adjustment of Seed Amount
When setting the required quantity of sown seed, use the sowing chart and carry out the calibration test then.
CAUTION!
1. Seeds for the seed container should be poured when the metering roller is completely closed (recommended),
or at the roller setting by at least 15 % less than indicated in the sowing chart.
2. With the seed container is filled, and after each seeding test, you can reduce the sown seed quantity by no
more than one turn of the adjustment knob (to the left). Increasing the amount of sown seeds - without
restrictions.
3. With a larger reduction (without sowing test), slide the gate valve above the dispenser and empty the seed
dispenser, because the dispenser may be damaged
4. Increasing the quantity of sown seeds
–
without restrictions, within the range of dosing roller settings.
5. Setting of gear wheels: 1:1 (small wheel inserted into the large gear.)
Settings for fine seeds (of rapeseed type)
Do the following:
close the gate valve above the dispenser and empty the dispenser
unlock the adjusting screw knob
completely close the metering roller (at ‘0’)
set the resistance in the hex shaft cut-out (see Fig. 8)
–
