2.11 Lowering and
Raising Drill
This section refers to the lowering and
raising of the entire drill using the lift axle
cylinders.
Stay clear of wings and openers during
lowering and raising. Wings are extremely
heavy and are driven down with hydraulic
pressure. Disc blades and opener discs
are sharp. During lowering, openers will cut
or crush anything beneath them, and can
cause serious injury or death.
The centre section is held up only by
hydraulic pressure, and may slowly lower
over time. It may lower more rapidly if the
hydraulic system is damaged. They lower
rapidly if the hydraulics fail, or the Lift circuit
is set to Float.
Set tractor brakes / use Park to avoid
tractor movement. Remain clear of all tyres
and row units during raise and lower.
Do not lower while any folding or unfolding
operations are under way or partially
complete. Openers can dig in or drag on
ground and be damaged.
2.11.1 Lowering
Check that maintenance lock channels are
installed on wheel lift cylinders.
The drill should be lowered before folding
and unfolding (ensure that the working
elements are still raised).
Make sure all persons are clear of opener
sections.
The drill is lowered by selecting the 'road
transport' button on the control panel and
operating the tractor spool.
Do not stand on tyres. Wheels
may turn suddenly and without
warning if used as a step,
resulting in serious injury.
