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
completed. In particular, the transport hooks only
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.
Raising Drill (Transport Lift)
Transport Lift is on a dedicated hydraulic circuit. The
center main frame raises and lowers independently of
the opener sub-frames (which are raised and lowered by
the Opener Lift circuit).
The Transport Lift circuit also includes a cylinder for the
Transport Hooks, which lifts and restrains the
outer/forward ends of the wing sections when folded.
Transport Lift is normally used only after the drill is
folded. Opener Lift, and not Transport Lift, is used for
headland turns in field operations.
NOTE:
If the drill is unfolded, gauge wheels do not lift off the
ground during Transport Lift. The wing sections pivot,
and the gauge wheels remain on the ground. As they
do not caster, they can drag sideways if Transport Lift
is used before fold.
