Parking with Drill Unfolded
Negative Tongue Weight Hazard:
Lower parking stand, lower openers and remove hydraulic
down pressure before unhitching the drill in the unfolded
position. Unhitching in the unfolded position with the openers
raised could result in sudden elevation of the tongue, causing
injury or death. This drill has a negative tongue weight when
unfolded and openers are raised.
1. Remove jack from its storage location on top of
tongue and pin it on post on left side of tongue as
shown on page 20. Extend jack until weight of
tongue is on jack. Leave tractor hitched for the
moment.

2. Lower parking stands on outer ends of drill. Unpin
keeper pin and rotating stands down. Place a block
under foot of stand if it does not contact the ground.
3. Lower openers and reduce hydraulic down pressure
to zero.
4. Unplug drill hydraulic hoses and electrical lines from
tractor.
Pinch Hazard:
Use caution when removing the hitch pin. Slight tongue eleva-
tion may occur, even with openers and parking stands lowered.
5. Remove hitch pin first, then safety chain from tractor
draw bar.

