Your question is one of those which when asked (in innocence,by someone who has no idea at all) of someone who uses the equipment, causes hysterical laughter---all at your expense! It isn't your fault that they laugh, but the question is, to them utterly simple!

I will, however, explain.

A power take off, commonly refered to as a PTO, is a rotating shaft, usually 1 3/8" in diameter, with splines on it, located just above and in line with the tractor drawbar. It transfers power from the tractor engine (just like the driveshaft on a car or truck) to the towed or mounted implement. The splines on the shaft match the splines on the implement's driveshaft and there will be a device to lock the connection so that the driveshaft won't come off while operating, but can be disconnected easily when unhooking the implement.

There are also "mid mounted" pto and "front" pto locations on some tractors. The "Mid" or middle mounted pto is also in line with the centerline of the tractor, but faces forward and is located under the tractor. but in front of the rear axle and under the transmission.

Much more rare would be a "front" pto, which would be located between the front wheels, in front of the tractor and would be used with very specialized equipment. Front pto is highly uncommon.

Does this answer the question? Good luck with the Horse Farm Management class.
