You're doing a great job and pretty impressed with your work. Not your fault for cracks anyplace. In the 80's my buddy building pole barns on his own bought a J.D. 350. Amazing what the cute little thing can do but before long it was leaking coolant into the oil so I put new sleeves and pistons in it. Ran great but turns out it had a big crack in the frame than had been welded before. About midway of tracks. He eventually got divorced and dozer had to go of course. I'm certain it had a different style blade set up than yours though. A more modern design I think. Nice video, Thanks.
