Raise Tongue
12. Raise 3-point hitch or hydraulic hitch until wing
hooks on tongue clear locks on wings.
Complete Fold
13. Continue or resume folding until the wing locks
contact lock plate (under hooks).
14. Set Hydraulic Selector switch ( or in Figure 19
on page 27) to center/off or “Markers”.
Note: In center/off, the switch disables all solenoid valves
for Fold and Markers, locking both systems.
Lower Tongue
15. Lower 3-point hitch or hydraulic tongue until wing
hooks rest on wing locks.
Re-phasing Fold System
Over a period of normal use, the cylinders may get out of
phase. This is evident by wing gauge wheels not running
in their fully rotated positions in front of the planter.
Note: Planter must be folded to re-phase fold system.
See “Re-Phase Fold Cylinders” on page 24.
Lock Up Dry Fertilizer Drive
For transport, storage and planting without fertilizing,
lock up the fertilizer ground drive.
Note: Avoid operating the dry fertilizer meter when not
applying dry fertilizer.
Sharp Object Hazard:
Be cautious near the ground drive wheel. Wheel tines may be
sharp.
The standard dry fertilizer system is driven by a ground
contact wheel. When the planter is raised, a hydraulic
cylinder extends to raise the dry fertilizer drive wheel arm
and wheel out of ground contact. The arm needs to be
locked up, or the wheel may slowly lower. A rotating lock
arm
is provided that manually engages a tube
projection on the raised drive arm, or automatically
engages when a lowered drive arm is raised.
Refer to Figure 23
Remove the pin
holding the lock arm out of
engagement, allowing it to swing down. If the planter is
lowered, the lock arm engages automatically at next lift.
To disengage the lock arm, it may be necessary to
perform a brief lift operation to free the lock arm from the
tube projection.
