PTO ?

The plastic safety shield on the PTO should always be fixed and not spinning. This prevents loose clothing from getting caught on the PTO shaft and the operator being tangled up in the PTO shaft.

Dead on!

G'day over here now the plastic covers come with no chains the theory behind that is that the cover can turn with the shaft but must stop when you put your hand on it, this save the plastic bushes that the cover mounts to from wearing out. In reply to some of the other answers the chain is not there to hold the end of the pto up off the ground as this can deform the cover and/or the bushes and prevent it from spinning freely

Perhaps its just because that I'm old and mouldy but an opportunity to talk to someone in the land of OZ is just pretty darn neat to me. The theory of the plastic shield spinning freely to save wear on the plastic bushings makes very good sense. But if the plastic shield isn't rotating freely you would not know it until your jacket, along with you, got wrapped around the PTO shaft. I would rather have the chain holding the PTO cover stationary. That way If the safety PTO cover failed it would break the chain and you would know from the tractor seat that is was defective. I have been brush hogging with chained PTO safety covers for over 25 years and have never had one fail.

No, with the shear bolt broken there is nothing to keep the U-joint from spinning and working itself off the implement drive shaft. Maybe it does not happen too often but you don't want to find out the hard way, or do you?

Every piece of equipment that I have used with a shear pin (2 bush hogs. a tiller and a baler) have had a retainer clip to keep the PTO shaft from coming loose when the shear pin breaks.

No way would I even attempt to test this theory ... people do not put anything on or near a turning PTO.

I believe the chains serve a purpose ... the tracor end I always atatch to the drawbar and the implement end to the implement.

I do agree not to hang the stored shaft from this chain.
