Hitching with PTO
The pump may be installed before or after hitching the
planter to the tractor. If the planter has a 3-point hitch,
installing the pump first may be easier.
Refer to Figure 6
1.
Completely remove the socket head cap screws
from the coupler
.
Note: If the coupler is not mounted, or you need to
change to a different coupler, see page 9.
2. If space is constrained inside the tractor PTO shield,
rotate the coupler to an orientation that eases later
inserting and tightening of the cap screws.
Prepare Tractor
3. Back the tractor into close proximity to the planter
(within pump hose reach of the PTO shaft).
4. Shut down the tractor and remove the key.
5. Make any necessary adjustment to the tractor
drawbar
. This might include:
inverting an offset drawbar, and/or
relocating a clevis assembly (not shown).
6. Clear the PTO shaft of any pins or wires that
might prevent the pump from fully seating on the
shaft.
Mount and Pump
7. With hydraulics hoses to rear, and torque arm to
right of drawbar, slide the pump assembly fully onto
the PTO shaft
.
8. Insert one socket head cap screw into the larger
counter-sunk clamping holes in the aft end of the
coupler. The screw head fully seats, below the
surface of the coupler, in these holes.
See NOTICE at right.
9. Adjust the position of the coupler on the shaft until
the screw threads are in the PTO shaft groove
.
Thread screw in until finger tight.
10. Insert the other socket head cap screw in the other
side of the coupler. Thread it until finger tight.
11. Pull and twist the pump assembly to verify that the
socket head cap screws prevent sliding along the
PTO shaft.
12. Tighten both cap screws to
1 ⁄
2
-13 Grade 8 torque
specification (105 foot-pounds, 145 N-m).
13. Complete normal planter hitching.

Entanglement and Flailing Equipment Hazards:
Do not use a driveline, shaft extension, adaptor or external
gearbox with the PTO pump. Use the pump, with a Great
Plains coupler, only on a native 1000 rpm 20- or 21-spline
stub shaft. Extra fittings create entanglement hazards. Fittings
also destabilize the shaft, and may make it impossible to
adequately secure the pump against torque and shaft slip.
Equipment Damage Risk:
Use the clamping holes
. Do not use the drive-out holes
(the smaller forward holes that are threaded to the surface).
Drive-out holes are used only during dismount. The screws
only partially thread into these holes. These holes do not
adequately secure the pump to the shaft. The pump is likely to
fall off if these holes are used for pump mounting.

Entanglement and Crushing Hazard:
Never perform any mechanical adjustment, PTO setup or
hitching with the tractor running. Take no chances that the
PTO might become active. Entanglement or flailing equipment
can cause serious injury or death faster than you can react.
