PTO Stump Grinders
I am having great sucess with the Miller brand PTO stump grinder mounted on my New Holland 55 HP turbo diesel engine. I started off using a cheaper brand that was just horrible. Did some more research and this guy who makes them in Indianapolis used to be a design engineer for vermeer and at one point, made parts as a subcontractor for vermeer too.
I have the Miller Pro 75. Where I live, I don't have to worry to much about turf, sprinkler systems and gates, ect. It is a great alternative to having the 40K stumper. Since I use a Morbark PTO chipper, I usually wait for the stumps to accumulate and grind them all together since it can be a slight pain to hook up/disconnect the set up. I haul the tractor with the stumper on an 18' skid steer trailer behind my dodge 2500 turbo diesel.
I've toyed with grapple hooks for the front end loader but currently using pallet forks to lift/load logs from the site.
Miller has a website and if you google him I'm sure you will find him. He does all of his own machine work/welding. Excellent quality machine for about 8K. Had to expand the hydraulics on the tractor to accomodate the 3 spool lever set up that controls side to side, up and down and in and out motions of the grinder.
