Folding the Drill
Machine Damage Risk:
Fold only when the drill is raised and locked up.
Fold the drill on level ground with the tractor in neutral.
If your drill has markers, be certain they are folded and
their control switches are off before folding.
Pinch Point and Crushing Hazard.
To prevent serious injury or death:
•
Always use transport lift locks when drill is folded.
•
Fold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
•
Stay away from frame sections when they are being
raised or lowered.
•
Keep away and keep others away when folding drill.
1. Set Drive/Lock selector valve to Lock.
2. Fold markers (Option). See page 32.
3. Raise drill with lift cylinders until cylinders are fully
extended. Install lock channels over extended
wheel-cylinder rods. Six cylinder rods total. See
4. Retract the Lock cylinder circuit lever to:
• disengage the tool bar locks (2),
• disengage swivel locks (2),
• disengage caster locks (2), and
• enable the self-latching transport lock (1).
Set circuit to Neutral. Do not Extend.
There are two key points to remember when
operating the lock cylinders.
a. All seven lock cylinders are plumbed together,
and all move at the same time.
b. Operate the lock circuit lever (Retract/Neutral)
only once to fold. As the cylinders move, they
unlock 6 points then stop in a “ready to fold
position.” When the drill is folded, the 7th lock,
spring loaded, snaps shut, locking the drill.
5. Extend the Fold cylinder circuit lever to slowly fold
wings forward. The transport lock automatically
captures the right wing tool bar for transport.
It may be necessary to ease forward slightly with the
tractor to assist wings in folding completely.
Pinch/Crush Risk:
Drill Center section moves back while
folding. Tractor may move forward. Allow at least 10ft (3m)
clearance behind drill and ahead of tractor when folding.
