to get a dozer unstuck is very easy, I have a d6c, 10 k model and its been stu ck a few times but what u do is cut a tree about 18in to 2 foot around and long enought to go from track to track chain it up to the tracks one chain on one track and the other to the other track put in gear and the tree will give u tracken dont let it hit the hitch on the back of dozer its a ride u will never forget
