Raising/Lowering Planter
A 3-point planter is raised and lowered using the tractor
3-point hitch.
A 2-point/lift-assist planter is raised using the 3-point
hitch in front, and the hydraulic lift assist cylinder at the
rear of the planter.
When lowering in field conditions, drive forward while
lowering openers into ground. Never back up with
openers in ground.
Hitch hydraulic circuit configuration during planting can
vary between tractor models, and due to field conditions.
Great Plains recommends starting with the hitch set to
Float or Position/Depth Control (and not Load Control or
Draft Control).
Lift Locks
Use parking stands (page 15) to hold front of implement
at raised for parking, maintenance and storage. Raise
parking stands for transport.
On twin- and triple-row models, use the lift-assist cylinder
lock to hold the planter rear at raised for transport,
parking, maintenance and storage.
Refer to Figure 9
To install the cylinder lock channel:
1. Remove pin and lock channel from storage hole
in right side of lift-assist weldment.
2. Raise planter to transport position (page 20). Set lift
circuit to Neutral to hold at raised.
3. Install lock channel on cylinder rod. Secure with pin.
4. If parking, storing or performing maintenance or
adjustments, lower parking stands (page 15).
5. Lower planter onto stands and lock channel.
Raise planter, and hold at raised, before removing lock
channel.
Machine Damage Risks:
Always fold markers (page 33) before raising or lowering.
Always raise the planter for any reverse/backing.
Except on pavement, begin forward motion before lowering, as
rows move backward slightly as arms swing up.
