Introduction
PTO SAFETY WARNINGS
1. Always disengage the PTO, shut off engine and remove the keys before leaving the tractor seat.
2. Keep the tractor's master shield in place at all times.
3. Missing or damaged shielding is the main reason for driveline entanglement. Keep All Guards on and in
good condition. Check guards frequently.
4. Never step across a rotating powershaft. Always walk around the revolving shaft even if guards are in
place.
5. Dress for safety. Do not wear loose fitting clothes or jewelry and keep long hair covered or pulled back.
6. The tractor drawbar should be adjusted to the length specified in the driven machine's manual. This will
help prevent driveline stress and separation on uneven terrain and in tight turns.
7. A PTO shaft may break or separate during operation if improperly installed or adjusted. Be sure PTO shaft
is installed properly.
8. Never perform maintenance or adjustments until both the driveline and the machinery have stopped
moving.
9. Warn anyone who might come near an operating PTO about the entanglement hazard.
10. Regularly test driveline guards by spinning or rotating them to ensure the have not become stuck to the
shaft.
11. Always use the driveline recommended for your machine. Never switch drivelines among different ma-
chines.
12. Reduce PTO shaft abuse by observing the following:
a. Avoid tight turns that pinch rotating shafts between the tractor and machine.
b. Keep excessive telescoping to a minimum.
c. Engage power to the shaft gradually.
d. Avoid over tightening of slip clutches on PTO driven machines.
