Good luck finding one used boss, they are real hard to come by since everybody wants a loader and those that have one never sell them. Best bet is look into a new after market loader.
Oh well thats what I thought...how about the possibility of a dealer still having a new one around somewhere ? Are the Kubota loaders far superior to a aftermarket?
There are many after market brands of loaders from Woods, to Bush Hog to Coyker. You may get lucky and find something on Tractor House but chances are it wont be in your back yard and you'll have to get it shipped. You're looking at spending some where in the area of $3500 to $4500 for an after market loader from Woods or Bush Hog.
