there are a ton of these for John Deeres, infact, i know a guy who has one he wants $100 for. the front frame is cut off but wouldn't be hard to make another mount for any other tractor. check out
www.weekendfreedommachines.com and see what they might have to say. i have seen at least 3 of these machines at different shows on different John Deere tractors. all with the Didier name on them.
