Unfolding the Air Drill
Unfolding Safety Information
Roll-Away Hazard:
Unfold only on hard level ground. Allow ample room. Drill,
tractor, or both must be free to move during unfolding. On a
slope, roll away could occur, causing an accident resulting in
death, serious injury and substantial property damage.
Pinch Point and Crushing Hazards:
Keep people away from the drill and tractor during unfolding.
The distance between the tractor and the seed structure
decreases by 3.2m (7.5ft) during unfolding. Drill, tractor, or
both will move during this operation. Wings will tilt down and
swing out. Risks include:
▲ Pinching or crushing at pivot points and at multiple sites in
pivoting assemblies. Stay clear of the wing sweep arcs.
Coulters and row openers are sharp.
▲ Crushing under lowering/moving wing wheels, under mov-
ing transport wheels, under lowering wings or under lower-
ing openers.
Falling Hazard - Tires Not a Step:
Do not use tires as steps or platforms. Wing gauge wheel tires
are off the ground in transport lift. Front and rear main trans-
port tires can be lifted and free to spin on unlevel ground and
at some weight-transfer and row down-force settings.
General Cautions:
▲ Unfold only with markers resting in transport cradles.
▲ Unfold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
Do not unfold with openers lowered, or machine damage will
result.
