Refer to Figure 31
If caster locks are engaged (wire handle
and
indicator in FIELD position), they must be released
before folding.
5. At each wing caster, move the lock control handle
to the ROAD position.
6. If the indicator end of the lock does not
immediately snap up from FIELD to ROAD, some
pivot tension is holding the pawl end of the lock
in
the plate detent . Raise and lower planter fully to
release load on lock plates to allow them to come
open. Move the planter forward or back a short
distance until both locks unlock.
Refer to Figure 32
7.
Set CFM Marker/Fold switch to Fold. LED above
switch blinks continuously.
8. Activate (normally Extend) tractor Marker/Fold
hydraulic circuit to fold wings. Sequence begins with
releasing of tongue latch (Refer to Figure 22 on
page 25). Before folding completes …
9. Raise planter tongue (“Raising/Lowering Tongue”
on page 18). This must be done before folding
completes.
Refer to Figure 33
Note: If tongue is not raised prior to folding complete,
wing locks will be above transport hooks and
unable to secure wings to tongue.
If this happens, partially unfold planter, raise
tongue, and refold.
10. When fully folded, lower tongue so that wing locks
engage transport hooks .
11. Set CFM Marker/Fold switch to Marker.
Note: Set switch to marker even if markers are not
installed. This switch position sets the fold and
caster swing arm cylinder solenoid valves off,
providing additional protection against unfolding.
12. Set Marker/Fold circuit lever to Neutral.
13. 3-point: lower hitch completely
Hydraulic tongue: Set hitch circuit to Float (not
Neutral).
Transport Hazard:
Wing locks must be engaged for safe transport, and planter
tongue must be lowered to keep wings locked.
Hydraulic tongue, if installed, must be in Float.
Caster locks must be disengaged for transport.
