PTO Unhitching
The pump may be dismounted before or after unhitching
the planter and tractor. With a 3-point planter or 3-point
hitch, dismounting the pump last may be easier, which is
the order shown on this page. For safety, have the tractor
completely shut down during PTO dismounting.
1.
At the tractor, shut down the PTO.
Note: The PTO may be shut down suddenly or gradually.
The fan circuit includes a bypass to recirculate
excess pressure during deceleration. The fan is
only sensitive to sudden acceleration.
2.
Do not approach the hitch area until the PTO shaft,
and the fan, have slowed to a complete stop.
3.
Mechanically unhitch the planter per the Operator
manual. Leave the PTO pump mounted at this time.
4.
Pull the tractor forward enough to allow access to
the PTO pump. Put the tractor in Park or Neutral.
Engage the parking brake. Shut the tractor down.
Remove the key.
5.
Loosen and remove the socket head cap screws
at the PTO coupler
6.
Slide the PTO pump off the PTO shaft.
If, after removing the cap screws, the coupler is still
grasping the PTO shaft too tightly to remove, use
the drive-out holes
to pry the clamping halves
apart. Insert the cap screws in the forward drive-out
holes. Tighten them alternately until the coupler is
free.
7.
Store the pump on the planter. Insert the torque
arm
into the storage mount
.
The storage mount is located on the front of a
3-point hitch and on the right side of a pull-type
tongue at the hitch bolts.

Entanglement Hazard:
Remain clear of a rotating PTO shaft. Even when coasting to a
stop, a PTO shaft can have enough residual torque to inflict
serious or fatal injury.
Hot Surface Hazard:
Remain clear of the pump reservoir during unhitching.
The oil may be hot enough to inflict a painful burn.
