I have a 3 pt 60" finish cut mower deck (king cutter) from tractor supply that is about 4 years old. I want to add a 10-15 hp engine to it (mount it to the deck) to provide its own power supply so i can tow it with an ATV. I would like to be able to convert it back to tractor/3 pt use occasionally. Does anyone have an idea how I can accomplish this? It would need some type of connection to the exsisting shaft drive and poss some type of "clutch" to engage it so that it would not have the drag of the blades or gears when trying to start it.
