Hitching with PTO
Hitching procedures are different for 540 rpm pumps
(below) and 1000 rpm pumps (page 12).
Hitching with 540 rpm PTO
The pump may be installed before or after hitching the
planter to the tractor. With a 3-point planter, installing the
pump first may be easier.
Prepare Tractor
1.
Back the tractor into close proximity to the planter
(within pump hose reach of the PTO shaft).
2. Shut down the tractor and remove the key.
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.
Refer to Figure 7
3.
Make any necessary adjustment to the tractor
drawbar
. This might include:
inverting an offset drawbar, and/or
relocating a clevis assembly (not shown).
Entanglement and Flailing Equipment Hazards:
Do not use a driveline, shaft extension, adaptor or external
gearbox with the PTO pump. Use only a native 540 rpm
6-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.
Mount Pump
4.
Clear the PTO shaft of any pins or wires that
might prevent the pump from fully seating on the
shaft.
5. With hydraulic hoses to rear, and torque arm to
right of drawbar, slide the pump assembly fully onto
the PTO shaft.
Secure Pump
Refer to Figure 8 (shown with pump off for clarity)
6.
With the torque arm firmly against the drawbar:
loop the chain once
around the drawbar,
then through the anchor point ,
then around the drawbar at least once more,
then through the keyhole slot in the torque plate.
The drawbar loops prevent pump rotation.
The anchor loop retains the pump on the PTO shaft.
