Folding
Pinch Point and Crushing Hazard:
To prevent serious injury or death:
▲ Always use transport 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 or unfolding
drill.
Fold the drill on level ground with the tractor in neutral.
Clearance/Equipment Damage Risk:
The hitch-to-hitch length of the 3S-4010HD/HDF increases by
12 feet (3.7m) during folding. Allow at least 12 feet (3.7m) of
clearance ahead of and behind the drill when folding.
Tractor can move forward during folding, if tractor is in neu-
tral with brakes released.
Center section of drill can move backward during folding if
tractor is in Park, has brakes set, or otherwise cannot move.
1. Raise drill with lift cylinders until cylinders are fully
extended.
2. Install lift locks. See “Raising” on page 20.
3. Retract the Lock cylinder circuit lever to:
disengage the tool bar lock,
disengage swivel locks,
disengage caster locks, and
enable the self-latching transport lock.
Set circuit to neutral.
4. Extend the Fold cylinder circuit lever to slowly fold
wings forward. The transport lock automatically cap-
tures the right wing tool bar for transport.
Note: It may be necessary to ease forward slightly with
the tractor to assist wings in folding completely.
