It's nice to see someone so young taking an interest in these old tractors. They were built to last and in not many more years will be 100 years old and still working with proper maintenance by young people like this young man. The rest of us will be watching over you and rooting you on young man!
You can pull the clutch disc out of an M out the bottom too. I've done it. I'm can't say whether the flywheel will come out the bottom on an M or not but I believe it will too.
Good video, thanks for the information. I need to check this out on both my H and M. I’ll make a video if mine need adjusted and give you a shout out. P.S. Are you wearing those shoes with toes? Those things freak me out lol.
