I know it is a silly question but I figure what the heck. What is the smallest dozer you have pushed with. Was self loading the other day finishing up a little job and got to some hard wet clay and need a little help. So what all I had was the good old 850 case and the nice 750J deere with GPS. So instead of smoking a tranny we pushed with the 850http://www.heavyequipmentforums.com/images/smilies/biggrin.gif. looked funny as could be but work great in a pinch. So it got me wondering if any one else had to "make it work".
