Unfolding
Crushing Hazard:
Bystanders could be crushed under the wings or caught in the
wing fold mechanisms. To avoid serious injury or death, keep
all persons well away during implement unfold.
Unfold the implement for adjustments, field operations,
maintenance, parking and storage.
1. Unless the implement was folded, with the currently
hitched tractor, only a short time ago, check for
evidence of oil leaks. Check the ground at hitch
connections, hose fittings and under cylinders.
2. Be aware of vertical and horizontal clearances
needed to unfold the implement.
3. Put tractor in Park with parking brake engaged.
4. Verify that the wing lock pins are not installed in the
lower lock holes (page 18).
5. Clear all persons from on or near the implement.
6. Use the tractor 3-point hitch to raise the implement
so that the rear of the center row units are off the
ground.
Refer to Figure 14

Slowly move fold circuit lever(s)
a
to Extend. Observe
the unfold operation.
8. Wait for both wings to reach the fully unfolded
position. Set tractor remote(s) to Neutral to lock at
unfolded.
2014+ Independent Fold
LC40 models manufactured in 2014 or later have
independent left and right fold circuits. In the field, one
wing may be partially or completely folded to clear
obstacles or perform point row operations.
Tipping Hazard:
Never unhitch, park or store a partially folded implement.
A partially folded implement could topple backward or
forward immediately or at some later time, causing serious
injury or death, and certain severe equipment damage. When
unhitched, the implement is supported at the rear only by row
unit tools and spring tension. Slopes, soft soils, and soils later
softened by rain are particularly dangerous.
Do not transport partially folded. Clearance is insufficient and
steering may be unstable due to reduced tire traction on one
side.
a. 2014+ models have separate circuits for left and right wing fold. 2013- models have a combined circuit.

Equipment Damage Risk:
Do not leave a partially folded implement lifted for extended
periods of time. This places a needless unbalance load on the
tractor’s lower lift arms.
