4.3 Sowing headlands
Figure 4.3
In dry and fine conditions, the headlands should be sown first. In wet conditions or on soils
susceptible 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.
4.4 Engaging the drill
Figure 4.4
The drill must always be moving forwards when it is first entering the soil. Hold the hydraulic le-
ver in the pressure position, i.e. in ‘lowering’ position until the bout markers are fully extended.
Check on the Control box that bout marking has advanced and that the relevant lights come on,
go off or change over during lifting.
During sowing, all switches should normally be in the ‘up’ position, which means that Lift stop is
off, Low lift is on, Autostep is on and that the feed switches are turned to the on position.
