Unfolding
Unfold the drill on level ground with the tractor transmis-
sion in neutral.
1. Fold markers, if installed.
2. Extend the Lock circuit lever to:
enable the tool bar lock,
enable the swivel locks,
enable the caster locks, and
release the transport lock.
Set circuit to neutral.
3. Retract the Fold circuit to unfold drill.
The tool bar, swivel and caster locks automatically
engage, either at the completion of unfolding, or dur-
ing next forward movement of the drill.
4. Extend the Lift circuit as needed to raise the lift cylin-
der bodies off their lock channels.
5. Remove lock channels from all six lift cylinders.
Store lock channels.
6. Lower drill. See “Lowering” on page 20.

Lock-Out Hubs
To reduce wear on drive system components during
transport, the rockshaft gauge wheels can be locked-out
(disconnected) from the drive system.
Hub Lock-Out
Refer to Figure 22 (which depicts the right rockshaft wheel
with the drive system engaged)
1.
At each rockshaft wheel, locate the lock-out pin
receiver
. Note that it has both shallow and deeper
detents.
2. Pull the cross-pin away from the sprocket, rotate
the pin 1 ⁄
4
turn, and release into the shallow detents.
Hub Engagement
1. At each rockshaft wheel, pull the cross-pin away
from the sprocket, rotate the pin 1 ⁄
4
turn, and release
into the deep detents.
Note: The pin usually does not fully seat immediately, but
does so during the next full rotation of the wheel.
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.
The hitch-to-hitch length of the 3S-4010HD/HDF decreases by
12 feet (3.7m) during unfolding.
Keep all persons away from all drill wheels during unfolding.
Tractor can move backward during folding, if tractor is in neu-
tral with brakes released.
Center section of drill can move forward during folding if trac-
tor is in Park, has brakes set, or otherwise cannot move.
