2. Fold markers (Option). See page 36.
3. Raise drill with lift cylinders until cylinders are fully
extended. Install lock channels over extended
wheel-cylinder rods. Six cylinder rods total. See
page 25.
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.
Note: 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.
Note: It may be necessary to ease forward slightly with
the tractor to assist wings in folding completely.
