Folding
These instructions presume that the implement is
unfolded and lowered.
1. Set lift/fold circuit to Float.
2. Raise the 2-Point hitch.
3. Raise the lift-assist circuit. The wings begin to fold,
and are stopped by the wing locks. The lift-assist
then raises.
4. Set the lift/fold circuit to Neutral to hold at lift.
5. Remove spacers (page 43).
Install lift-assist transport locks (page 50).
6. Deploy parking stands if the implement is to be
parked at the folding spot.
7. Lower the lift-assist circuit (which causes unfolding),
just until the wings are level. Set the fold circuit to
Neutral.
Refer to Figure 24 and Figure 25
8.
Swing the wing locks up and out of their engaged
positions, and into their reset
positions.
9. To secure wing locks during transport, lower down
into transport lock holder and slide pin through
holder and wing lock handles. Secure with cotter pin.
10. Raise lift-assist circuit once more, which causes the
wings to fully fold. When they have folded, the
lift-assist raises cylinders to raise the implement rear.
For parking/storage/service, lower the implement onto
parking stands. For transport, the lift-assist circuit may
be left in Neutral fully raised, or lowered onto the lock
channels and set to Float or Neutral.
For parking:
11. Lower the lift circuit just until the cylinders rest on the
lock channels. If the wings begin to unfold, reverse
the circuit briefly.
12. Lower the 2-point hitch.
13. Set the lift/fold and 2-point hitch circuits to Float.
