Drive-Off Unload
If a side dock or pit dock is available, all Nutri-Pro
®
imple-
ment configurations may be safely removed by a 3-point
tractor with adequate lifting capability.
The lift must be performed in full 3-point mode.
All implements (including Pull-Type) have suitable pins in
the lower holes of the hitch weldment.
2-Point and Pull-Type implements do not include a 1
1 ⁄
4
in
hitch pin for the top hole. You need to provide this if drive-
off unload is desired.
On 2-Point and Pull-Type implements, do not attempt to
use the lift-assist circuit while the implement is on the
trailer bed. The lift-assist circuit may not be charged with
oil.
Machine Damage Risk:
On 2-Point implements, the lift-assist circuit is also intercon-
nected with the fold circuit. On 40-foot models, using lift-assist
on the trailer bed causes wing cylinder movement, which could
cause machine or trailer damage.
Note: The lift-assist caster assemblies are likely to settle
downward when the implement is lifted. This is nor-
mal, but they provide no support for the implement
during unload.
Drive-Off Unload Steps:
12. Hitch the tractor 3-point to the implement. See the
Operator manual (407-313M or 407-502M) for hitch-
ing details. Do not connect the hydraulics.
13. Support most of the weight of the implement with
the tractor hitch.
14. Release the straps or chains securing the imple-
ment to the trailer bed. Remove loose stands.
15. Pull the tractor forward.
16. Lower the implement onto its parking stands, or
other stands or supports.
