working in the snow

I am new to this bulldozer thing I have purchased a 1981 450c and have used it in the fall before the snow came. My question is when I used it the first time in the snow I was getting some spring compressing and a bang, is this caused by the snow packing up on the sprockets......should I loosen the track tension?

Unless you have snowshoes on it, you will probably always fight it, more so on warmer days and/or wetter snow. Eveny once in a while while you are pushing, get it on flat ground, no or little snow, and run it back and forth in high, that will tend to shake some of the snow out.

Don't you just love that sound??? BANG! I made some 'snow skirts' for my 450...haven't had a chance to try them though...very dry year!

I have no idea if it will help, but when I tried to noodle it out, I suspected the bulk of the snow falling into the bottom of the tracks was from it falling in when turning...the skirts may help prevent this somewhat.

Aloah Big Kahuna : Ist off you should be pushing sand in Hawaii rather than snow in Canada, Holes in the center of the pads are the answer to your problem. In the early 80's when the 850 Case 6ways came out they had no holes in the pads ( where the sprockets meet) , and we were constantly breaking the bolts holding the pads on. Then case went to a (want to say) 5/8" dia hole which wasn't much better. When they went to the big opening that solved the problem. You will find out you will have the same problem in certain clays.

Thanks guys for the replies, I think I might have the holes you guys are talking about......there is egg shaped holes between the 4 bolts holding on the pads....will try to loosen the tension on the tracks, at this time I have about 1 inch sag
