I have a 1953 JD 50 with a separate clutch for the pto. If I turn the small handle by the shifter to the left to engage the pto and lift the clutch handle to the right of the seat the engine bogs down and no pto action. The clutch handle doesn't snap into postion and wouldn't stay up by itself. Also if I disengage the pto and attach a driveshaft to the pto shaft ( with the engine shut off) I can use use a prybar in the u-joint and turn the pto shaft - but it is hard to turn. Where do I start?

First off you'll want to get a service manual. This is a complicated system that has several adjustments. The pictures and description is worth the low price any day. :good2:

There's a PTO brake. It's engaged when the PTO handle is down. If you lift the handle half way to 2/3 with the engine off, will it spin easily? If not, there's a mechanical issue that will require the PTO housing to be opened to find out the cause. If it does spin easy, it may be as simple as an adjustment to the PTO clutches internal in the housing.

Let us know what you find, then we can go into further troubleshooting.

Be aware the seal between the pto clutch housing & differential has been known to fail letting trans gear oil into pto housing damaging the pto clutch plates.

I have a service manual and i"ll check pto brake. Right after my post my son-in-law, who's not yet 40, went into the hospital with blood clots. He's fighting for his life and legs. Right now tractor problems don't much matter. But thank you so much for the help so far.

I'm sure there will be many people from here praying for your son-in-law. It is tough to deal with, but much tougher when the patient is so young.

jd 50

:hi: so sorry to hear about ur sil problems, I hope he get's ok. I have a 52 or 53 model 50, and I have done a partial rebuild on the pto. jd got me the clutchs from api I think that was the name. I needed all of them when we opened mine up. but I didn't have the same problem's like u seem to have, mine would just not spin and it was out of adjustment. be prepared to get ur wallet out deep for these little clutches, I had over $600.00 in them using this aftermarket co. in 2010. go to u-tube look up steiner brothers, they have how to videos . their is a series on replacing the clutches on a 50. good luck, and the best for ur sil. big jim p.s their was certain little springs that I didn't replace because several people told me they looked ok, I do not get the good snaping noise when enguaging it like my grampaps ,so I should of replacing them good luck also check with steiner's on price, and look and smell ur oil when u take plug out , it only takes 10 weight in their, if the seal inside tranny left go u will tell right away with the color and smell.

Thanks for the video and seal advice! Id have to watch that pto video another 20 times before i'll crack that pto open. I pass Steiners in Lennon, Mi every day on my way home from work. My son-in-law did 5hrs surgery today to unplug a clogged aorta and arteries to his legs. Before they could sew him back up his blood was clotting plugging up what they had opened. Prayer is his and our only hope. Thx
