This video is about Grandpaps Farmall M PT2.. its just a get her running and useable it can stay rusty it just has to run.

ANtique Tractor: The absolutely correct size is 3/4 with a 1 inch hex head. The IH bolts with one dot are like that.Hardware store bolts are gonna be 1  1/8 head. I use them when I can't get the original, but it's a pisser to use 2 or more sizes of wrench for the wheel clamps.  Save your 12 rim  clamps and throw that busted one out in the iron, they're common enough. Yer old man busted that wheel while plowin' I'd bet . Happened to me a few times, too. Wheel clamp bolts come loose and axle wedges it out and breaks the casting. Glad to see you workin' on 'er. Thanks for recording, Wes and Tim!!
