The tracks are a mess. I think one is not even JD chain. Certainly not for a 40 as the links are larger/longer. The other very worn. Those will be scraped and I have a nice set of 40 chain and regular pads to put on her. Of course some of the rollers are in sad shape. It steers OK but one of the brakes doesn't work too well. It has one welded clutch case so that will need replacing.
I has a JD 61 bulldozer blade that has had a second cylinder added. I'm big on originality but, I like the second cylinder and it's done pretty well, mirroring the original components on the other side.
I'm going to take it completely apart and redo it all, if I don't go bankrupt first. It may take a while as I don't have a lot of free time these days but I currently have a few weeks free to devote to getting started. I thought you guys might like to see the evolution so I'll start a journal of the project here.
