Hello friends, my pto was grinding when engaging pto, I checked my clutch adjustment against my service manual it was out of adjustment and I only had 1/8" of free travel. My manual has specs for an early model and a later model can't remember the year cutoff, but mine is a 1960 model and fell into the later category. The manual is out in the barn with the tractor, but if I remember correctly it's 1 1/2 - 1 3/4 free travel, and 9 3/4 pedal height. I could be off on those numbers but I adjusted it to exactly the specs it shows, and checked them 3 more times. It goes into travel gears just fine and at any engine speed without any issues smooth as butter. Pto was grinding before adjustment even at 425 rpm and with the clutch pedal against floor board it would still run the shredder, it's still doing it after adjustment, that's why I kept checking my measurements. I've tried leaving it against the floor board for about a ten count before trying to engage pto to give it time to stop, even at 425 rpm, makes no difference. It will disengage without issue, so I just shut down engine engage pto and crank engine with it engaged. My question is am I missing something, or is there a split in my future? I do have the clevis in the correct hole too, for the two stage to be used. The manual didn't say which position for it to be in when making the adjustment, but in the picture it shows it in the two stage hole, that's where I had it when I made my adjustment . Any ideas would be much appreciated. I have been on this site for a few years now and almost all my questions have already been asked and answered for me by doin a search, but I haven't found this problem in my search. I am forever grateful for the wagon loads of knowledge y'all have passed on to me and others. Gods blessings and happy Thanksgiving.
