Operation
Lowering and Raising
Crushing Hazard
Wings are extremely heavy and are driven
down with hydraulic pressure. Coulters and
opener disks are sharp. Stay clear and
keep others away from wings and openers
during lowering and raising to avoid
serious injury or death.
Crushing Hazard
Use lift lock and gauge wheel lock
channels when working above or beside
openers. Without locks, center section and
wings are held up only by hydraulic
pressure, and slowly lower over time. They
may lower more rapidly if the hydraulic
system is damaged and hydraulics fail, or
the lift circuit is set to float or retract.
Shoving Hazard
Drill length changes by 56 cm during
raising and lowering. Set tractor brakes.
Put tractor in park to avoid tractor
movement. Remain clear of all tires and
row units during raise and lower to avoid
serious injury.
Implement casters, row units, and gauge wheels
move during raising and/or lowering. The casters
may swivel. The tractor may move in some
circumstances. Set the tractor brakes.
Equipment Damage Risk
Do not lower while any folding or unfolding
operations are under way or partially
complete. Openers can dig in or drag on
the ground and be damaged.
Gauge wheel lock channels are provided to hold the
wings of an unfolded implement at the fully raised
position for maintenance only. These lock channels
are important for maintenance, but are not used in
normal operations.
Lowering
Falling Hazard
Wing gauge wheels, caster wheels, and
seed cart wheels, may have little or no
weight on them, and may turn suddenly if
used as a step. Do not stand on tires when
implement is lowered to avoid serious
injury.
1. Check that maintenance lock channels are not
installed on the gauge wheel lift cylinders.
2. Check that the center section lift lock is
disengaged.
If lock cylinder is extended, perform a brief
unfold operation (extend the fold circuit) to
retract the lock cylinder.
If the lock cylinder will not retract, perform a
brief lift operation (extend the lift circuit) to
free the pawl. If this fails to disengage the
lock, see “
3. Unfold the drill before lowering (page 27).
4. Make sure all persons are clear of opener
sections.
