The setup will work with a tractor that is not 'live pto'.
Newer tractors with live or independent pto's it gets a little different - still maybe could work, but gets different. Depends on model.
Some tractors could be damaged if they depend on oil pressure to lubricate certain shafts in the tranny. Old tractors likely don't have this issue, but you do need to be aware of it. Depends, again, on the exact model of tractor you are using.
You will be limited in distance of course by the cord. You will be limited in speed by the size of the electric motor. Smaller electric motor, and you will need to gear it down slower....
To make it work on a non-live pto tractor, put the pto in gear, put the tractor in a gear, couple the electric motor to a gear reducer to slow it down (sounds like the patent is looking for 60-120 rpm speed?), and couple the gear reducer to the pto shaft.
Sit on the tractor, release the brakes, and turn on the electric motor.
Drive the 25 feet the electric cord allows, at 1/8- 1/5 normal speed, and there you go. Tractor will have very little torq, and will not deal with a hill or ramp or any such very well.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
