Re: Welding Rebar on for grousers

I purchased 450B a few years ago that the pads were wore down to the top of the bolt, The pins and bushing looked liked they had been turned when I got the loader, so I purchased some flat bar I think it was 1" X 1" and 1" X 1/2" and welded it on with my millermatic 200 welder.
