Well it has been awhile to post but the 350 dozer is out of the shop now. I put new brake bands in it and new oil. The tracks have started to loosen up at the frozen pins ,at least 2 cans of wd40. Had a brush pile to move that my wife had made for the birds so I could burn it. Then I had 18 ton of stone to move, runs great and steers fine now. So it is in the shed waiting to straighten out spoil from a ditch cleaning this spring. Now I am working on putting a belt pulley assemble on my 400 row crop, will put some lighter oil in it to see if the tractor with shift better and the noise goes away, if not will be spilt. Stay safe , Jerry from Ohio
