Unfolding
These steps presume a implement raised and folded for transport,
such as at initial delivery. Follow the detailed instructions in
step 7 through step 15, beginning on this page, until this is a
familiar operation.
Refer to Figure 18
Locking valves are on the wing cylinders to prevent wing
movement during transport. Note the open and closed position of
the valves.
7. Move the implement to level ground with adequate overhead
and lateral clearances for the fold operation.
Remove Transport Locks
Refer to Figure 19
8. Extend lift circuit to lift implement off the transport locks .
9. Park tractor and implement. Ensure the tractor hydraulics are
depressurized and in the locked or closed (not float) setting,
10. Shut down tractor and remove the key.
11. Inspect fold/lift cylinders linkages and hoses for wear. If parts
are worn, the operator should have a qualified technician
replace worn parts.
12. If parts are in good working order, move transport locks to
the working position on lift mechanism link.
13. Move locking valve lever to the open position slowly on both
fold cylinders.
14. Ensure all personal, e.g., children are out of the danger zones.
15. Insert key into tractor and restart the tractor.
Equipment Damage Risk:
Raise before unfolding. If this operation is not performed, the
wing shanks contact the ground, drag, and may be damaged.
Unfolding: Unfold Wings (page 25)
16. Unfold the wings by extending the fold cylinders.
 One wing may reach the ground before the other. It is
not uncommon for the folding to be slightly -non-
symmetrical.
Refer to Figure 20
Hold the circuit at extended for several seconds after the wings
engage wing stops on center frame.
