Lowering and Raising Discovator
Lowering/Raising Safety Information
Crushing Hazard During Lowering:
Stay clear of wings, disks, shanks, and attachments during low-
ering and raising. Wings are extremely heavy and are driven
down with hydraulic pressure. Coulter disk and sweeps are
sharp. During lowering, coulters and sweeps will cut or crush
anything beneath them, and can cause serious injury or death.
Crushing Hazard While Raised:
Use transport locks (page 27) when working on implement.
Without transport 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.
They lower rapidly if the hydraulics fail, or the Lift circuit is set
to Float or Retract.
Shoving Hazard:
Discovator length changes during raising and lowering. Injury
is possible.
Implement wheels move backward during raising, and forward
during lowering. Tractor may move in some circumstances.
Set brakes / use park to avoid tractor movement. Remain clear
of all tires and ground engaging components during raise and
lower.
Equipment Damage Risk:
Do not lower while any folding or unfolding operations are
under way or partially complete. Coulter disks and sweeps can
dig in or drag on ground and be damaged.
