Using PTO Safely
The accessories covered by this manual rely on PTO power to
operate, and require an adjustment at the planter while the
PTO is running. The PTO pump is designed to work on a stub
shaft PTO, and leaves no exposed shaft in use.
▲ Use only a tractor with an approved master shield for the
PTO.
▲ Use all guards provided for the tractor PTO. Have minimal
or NO shaft exposed after connecting the PTO pump.
▲ Use only a rear-facing PTO. The provided hoses and torque
arms are not designed for use with a tractor-front or
tractor-side PTO.
▲ Use only the correct (540 or 1000) rpm PTO, or an
adjustable PTO set to the correct rpm (maximum).
Running at a higher speed could result in equipment failure,
and serious injury.
▲ Use only a PTO with the correct shaft, and for 1000 rpm,
matching Great Plains coupler:

▲ Do not use any other adaptor, coupler, driveline, extender
or external gearbox.
▲ Use only a “live” or “independent” PTO. If the PTO only
operates when the tractor is in motion, there is no safe way
to set the fan speed.
▲ Ensure that all involved personnel are trained on PTO
operations and hazards. Always know where all team
members are before, during and after PTO operations.
▲ Allow only essential personnel near the PTO during setup,
adjustment, operation and disconnection.
▲ Prior to PTO setup, remove any stray wire, rope or twine
found nearby. Should a loose end encounter the PTO stub, it
is taken up at up to 14 feet per second, and could wrap
around someone and pull them in.
▲ Wear only snug-fitting clothes, with no scarves, loose
strings, cords, ties, and no frays, when working near a PTO.
▲ Tie long hair back or gather it up under a well-secured hat.
▲ Shut the tractor off for PTO connections or disconnections.
Do not trust your life to clutches and throw-outs.
▲ A PTO shaft is a hazard at any speed, even when well below
rated shaft rpm, coasting to a stop, or idling.
▲ Never step on or over the master shield or installed PTO
pump.
▲ Be extra vigilant if any tractor PTO controls are external,
and in proximity to the PTO.
▲ Elevate pump hose slack so that ground contact is not
possible during transport or field operations.
▲ Keep all PTO safety decals clean and legible. Replace any
that are faded or damaged.
