Hi Dave yes it's one of Aaron Schmidt's X-treme Motorworks hydro dump cart , he's a Cub guy and check out his website he has 'mad' skills.
Brian ( come on man we call it 'custom' made ????) I know , I know , I'm cheating putting Bolens on it. You would have to see it up close and use it , I loaded and hauled 10 ton crushed limestone ( up hill both ways ????) last summer it performs flawlessly . IMO worth every penny!I guess it depends on which cart.... the Green one looks homemade
Archive back page 12 or 13 in the Bolens forum I posted it and what I did to it.I am positive that's a extreme motor works hydraulic dump trailer. I have been eying them up for a while.
