My Farmall 100 has a rough time getting in gear. When the clutch is fully depressed, I usually have to hold it for 10-15 seconds and keep trying to get it in gear. Usually, I end up still having to grind it a bit and force it into gear. Based on what I have read, it sounds like there is an easy way to tighten some yoke rod or toggle the yoke rod but it isn't clear. Hopefully, I don't have to take the tractor completely apart to tighten the clutch (which I believe is the problem). Any thoughts?
