Install Transport Rest
This topic is only for shipments with over-folded wings
(transport rest not installed). If the implement was
shipped unfolded, or has the transport rests already
installed, continue at “Install Nurse Tank Hitch” on
page 22.
Unfold Over-Folded Wings
Fully raise the implement. Set the parking stands to max-
imum height. Install lift cylinder lock channels on rear
casters.
If only a simple stationary hoist is available, use the fol-
lowing procedure:
Refer to Figure 25 (which depicts an NP40A - the procedure is
that same for NP3000)
1.
Orient the fold cylinders of the left hand (lower)
under-folded wing so that their rods can extend
without striking implement parts.
2. Connect the hoist to the top end of the right hand
(upper) over-folded wing.
3. Support some of the RH wing weight with the hoist.
4. Loosen the nuts on the U-bolts securing the right
shipping stand
to the wing.
5. Increase tension in the hoist until the stand
provides no support. Remove the upper and lower
U-bolts, and the RH stand itself. The stand and the
fasteners are returned to Great Plains.
Note: If an overhead moving crane is available, you can
use it to completely unfold the wings and then con-
nect cylinder rod ends. Lower carefully nearing full
unfold, as the wing end coulters or knives will con-
tact the ground (since the wing gauge wheels are
not yet installed).
6. Lift the wing until the fold cylinder rod ends may be
aligned with the wing lugs.
7. Connect the top wing cylinder rod ends.
8. Operate the fold circuit to unfold the wings. Only the
RH wing unfolds. Reduce the unfolding rate as the
wing end nears the ground. The wing end will be
supported by the outside coulter or knife until the
wing gauge wheels are installed.
9. Disconnect the cylinder rod ends of the RH
(unfolded) wing, to prevent refolding of the RH wing.
Orient the fold cylinders of the unfolded wing so that
their rods can extend without striking implement
parts.
Note: The lift-assist cylinders attempt to retract during
unfold, but are restrained by the lock channels.
They do extend to full length during fold.
10. Connect the hoist to the top end of the LH (folded)
wing.
11. Support some of the LH wing weight with the hoist.
12. Loosen the nuts on the U-bolts securing the left ship-
ping stand to the wing.
13. Increase tension in the hoist until the stand
provides no support. Remove the upper and lower
U-bolts, and the LH stand itself. The stand and the
fasteners are returned to Great Plains.
14. Lift the wing until the fold cylinder rod ends may be
aligned with the wing lugs. Retract the fold circuit as
needed to achieve alignment.
15. Connect the cylinder rod ends at the LH wing.
16. Operate the fold circuit to unfold the LH wing.
Reduce the unfolding rate as the wing end nears the
ground. The wing end will be supported by the
coulter or knife until the wing gauge wheels are
installed.
17. Connect the cylinder rod ends at the other (RH)
unfolded wing.
