Are you looking to have a plow to use on the FEL or a frame mounted unit like smaller tractors and trucks?
You can do either one.
A plow for the FEL on be bought from a few different places, like your Kubota dealer, on-line dealers, and around here even truck equipment dealers sell FEL plows for tractors/payloaders/skidsteers.
If you are looking for a frame mounted plow. I know that Meyers makes kits for this. Or a good welding shop could take any older truck plow and make a mount for it.
