David Brown PTO output shaft broke! Sheesh...

Slacker · Feb 28, 2006

While running the bush hog, the PTO output shaft (coming out of the rear diff) broke in half! It didn't strip the splines off, the thing actually broke in half. Shear pin in the bushhog didn't break....Tractor is a 1975 50HP and is a true Hoss. I've got to get this fixed....all my implements are cat 2 and my JD has a cat 1. Has anyone ever repaired a broken PTO output shaft? If it was welded up it would need the splines machined back in. I'm not sure where to look for the needed part. Brown tractors aren't that common in my neck of the woods.
Remind me to post pics this weekend.

WHy not just buy a new shaft and repair? OR why not buy a whole new pto shaft assembly? Follow the link, they are in stock and cheap...

John,
I'm not sure, but I think he means the PTO shaft on the tractor itself broke.

You should be able to get David Brown parts from a Case-IH dealer. Case bought out David Brown in the early '70's. I had a '76 990 and it had David Brown and Case on the hood. Got all my filters and parts from the Case dealer. The 990 DB was an excellent tractor.

There is a section, I believe, at www.ytmag.com for David Brown. If my memory is faulty, the Case section talks about them. Should get some help there.

Funny how some hardened metal will crystalize, both rear axles on the IHC 300 broke off, known problem, just the wrong metal. Wonder if the same with your pto shaft.

I believe Elmer is the resident David Brown expert in the Case forum. Shouldn't be a problem getting replacement parts.

Yep, elmer is the DB expert if he is still over there on YTmag.

If this fixes your tractor, you better post some pictures of that fine machine!
