Advice on sowing

3.3 Sowing headlands
Figure 3.3
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.
3.4 Engaging the drill
Figure 3.4
The drill must always be moving when lowered to ground. Keep the hydraulic lever in the pres-
surised piston, i.e., lowering position, until the bout marker has been completely folded out. Using
the Control Station, verify that tramlining has been advanced and that the correct lamp goes out
and the correct one lights and that the alternate during subsequent raising.
When driving, usually low-lift and auto advancing should have been selected.
If a seed coulter becomes blocked, do not go under machine unless it has been properly secured
with the yellow locking devices. See ”
2.26 Locking the lifting rams during service” on page 58
