Why this is the answer
The correct answer in the official bank: To move attachments and additional equipment operated by the tractor.
The PTO is a rotating shaft, usually at the rear of the tractor, that takes power from the engine and passes it to connected implements such as mowers, sprayers and balers. This lets the tractor drive attachments and additional equipment, not just pull them. Towing is done with the hitch or drawbar, and engaging the front axle is part of the four-wheel-drive system, not the PTO's job.
