Crushing Hazard:
Keep all persons well away during folding operation.
Bystanders could be crushed between the folding drill boxes
and the drill tongue.
1.
Park tractor and drill on level ground with tractor
transmission in Park. Be aware of clearance needed
to fold drill.
2.
Fold up markers if installed. See “Marker
Operation” on page 43. Return selector valve
handle to Fold position.

3.
Opener subframe must be raised for folding. Position
all six opener lock handles in ROAD position and
completely raise openers. See “Raising and
Lowering Openers” on page 26.
Note: The opener transport lock handles are spring
loaded and can be moved to ROAD position with
openers up or down, but locks only engage when
openers are completely raised. There are two locks
on each drill section.
4.
Make sure transport lift cylinders and front box lift
cylinder are completely retracted (drill is lowered,
although openers are raised).
5.
Slowly supply oil to rod (retract) end of fold circuit.
Completely fold wing frames until both wing gauge
wheels contact tongue tube.
Fold (for transport) is not complete until Transport Lift is

engage, lift and secure the wings as part of Transport Lift
(the next topic).
6.
Allow transport lift cylinders to settle back against
lock channels.
7.
Before transporting, check that hydraulic cylinders
are holding lock channels securely.
