sounds like you should just buy a 1 ton dump truck, i know the 94-02 chevy 4x4 3500 dump trucks can be found quite cheap in excellent condition. i would look on craigslist for one of those, then you can tow your mowers and suck leaves with the loader mounted in the plow frame. plus you would now have a second plow truck if you want. I know where a rack body dump chevy 3500 is sitting on the side of the road for sale, i could get you the number if you want.
