PL5500 Planter
Preparation and Setup
Set-Up PTO Pump
Entanglement and Flailing Equipment
Hazard
Do not use a driveline, shaft extension, adapter, or
external gearbox with the PTO pump. Extra fittings
create entanglement hazards. Fitting also
destabilize the shaft, and may make it impossible to
adequately secure the pump against torque and
shaft slip. Never alter and remove any existing
guards on the tractor or PL5500 planter at any
point of PTO pump assembly kit installation.
Contact your Great Plains dealer for service.
Entanglement Hazard
Do NOT use any pins, cross-bolts, or wires to secure
the PTO pump to the PTO shaft. Such fasteners are
not required for safe PTO pump operation, and
would add a needless entanglement hazard.
Electrocution Hazard
When disconnecting the electrical harness from the
tractor battery, disconnect the negative terminal
first and the positive terminal second. Ensure that
the battery rings do not touch any other surfaces.
Equipment Damage Hazard
The oil cooler electrical harness should be
disconnected from tractor battery whenever not in
use. Failure to do so may result in damages to the
tractor battery. If not properly disconnected when
not in use or during maintenance, storage, and
transport, the oil cooler may unexpectedly operate.
1. Back the tractor into close proximity to the
planter; within pump hose reach of the PTO
shaft. The planter may be hitched to the tractor
before or after the PTO pump is mounted and
secured.
2. Turn the tractor off and remove the key.
3. Make any necessary adjustment to the tractor
drawbar (1).
4. Clear the PTO shaft (2) of any pins or wires that
might prevent the PTO pump (3) from fully
seating on the shaft.
5. With hydraulic hoses to the rear, and torque arm
to right of drawbar, slide the pump assembly fully
onto the PTO shaft (2).
6. With the torque arm firmly against the drawbar:
a. loop the chain once (4) around the drawbar,
b. then through the anchor point (5),
c. then around the drawbar (4) at least once
more,
d. then through the keyhole slot (7) in the torque
plate.
The drawbar loops prevent pump rotation.
The anchor loop retains the pump on the PTO shaft.
7. At least one full chain link must be exposed at
the keyhole slot (7) on the decal side of the
torque arm plate.
If there are more than a few chains loops left
at the plate keyhole, route any excess chain
through the anchor point and/or around the
drawbar.
8. Pull and twist the PTO pump assembly to verify
that the chain is sufficiently taut to prevent
excess pump rotation or sliding along the PTO
shaft.
The PTO pump system is a closed system,
so any visible fluid may be an indication of a
leak.
