Comments:..I was playing this game in a JCB JS330 earlier today. Great fun when you are sat practically laying flat in the cab sliding backwards ..... We beat the hill eventually...
First of all, I know the dozer operator was keeping his blade low incase he starting slipping backward, he could dig it in and stop himself. That is good, but, when you realize you are slipping in the mud, you back out of the way and let the excavator scrape out the top couple inches of mud where each track will travel. And for the excavator, unless you have a rock or tree stump to grab onto, you push yourself up the hill, not pull, because when you put that bucket in the ground in front of you, you are taking too much weight off the tracks for good traction. Lastly, some people suggested going up the hill on a 45 degree angle or sideways....wrong! When you put tracks on mud or ice sideways, the tracks act like sled runners and when you get sliding down the slope on a dozer or excavator, you stand a good chance of flipping the machine and having a real bad day. Fifty one years experience operating dozers, loaders, and excavators. I should know something.
Those tracks look pretty smooth and flat. Most of the ones I usually see on dozers and track hoe's have some type of prominent raised tread ribs for better traction, like on an army tank.
