Figure 3.3
Check regularly whether the seed level is sinking evenly in both windows.
Get into the routine of quickly looking over the drive shafts, gears and chains to see that every-
thing looks normal and is still in place.
Regularly ensure that the seed box rollers rotate at uniform speed.
This sowing system has been developed to deliver even seed feed and reliable sowing rates.
Väderstad-Verken AB shall not be held liable for any claims for indirect or consequential damages
relating to losses incurred in connection with the use of the drill. In addition Väderstad-Verken
AB accepts no liability for losses arising from incorrect use of the sowing or seed feed functions
of the drill or any part thereof.
It is the responsibility of the operator to use properly pre-treated seed, treated with dressings which
do not impair or prevent seed feed. Note that the use of seed types larger than normal pea seed can
block the seed feed system.

Sowing headlands

Figure 3.4
In dry and fine conditions, the headlands should be sown first. In wet conditions or on soils sus-
ceptible to compaction, higher yields can be obtained if the headlands are sown last.
The headlands can be marked out by finishing off the last tillage operation before sowing (e.g. au-
tumn harrowing) by harrowing the headlands last. This ensures that the outermost headland bout
is at the correct distance from the edge of the field.
