I broke the drive shaft on my 5 ft. bushhog squealer mower at the coupler (the part where the universal joint attaches to the mower gears) it was a pretty clean break. Can the shaft and coupler be ground clean and welded successfully. I am going to try any way but has anyone got any good ideas or experience? Thanks I almost enjoy having these problems so I can use this forum.

In my honest opinion, (and experience!) having a drive shaft welded together, even by an expert welder, is a complete waste of time.
Buy a new shaft.

SH,
Agri-Supply sells a complete shear pin connected PTO shaft for around $65 and the Slip Clutch complete shaft for less than $150. That is not alot compared to what could blow up if that weld breaks. I would bet they have a shaft that will work

I Cannot tell exactly what part you have broken, but the rule on welding it should be this. If a "re-break" where you weld it will turn loose the PTO shaft, then buy a new part - do not weld. A broken shaft, turning on the tractor PTO could tear up your whole tractor and maybe you. Don't risk it.

I had one rewelded by a local welding shop who said they had done many of them but this was seldom a satisfactory fix because it wasn't done in a jig and they had a hard time getting it as straight as it should be throwing the whole thing out of balance. It worked okay for me but it wasn't right. Got me through that cutting and I brought a new one. I really think you would be better off looking for one in a bone yard. Good luck.....

First off, this is beyond my welding skill. That being said, my cousin, a professional welder, welded up a broken shaft for another cousin's corn picker. If I recall he ground down opposite sides almost to a point, but left part of the original break to lock together in lining up the weld. I think he used a torch and a high strength rod (maybe an RG60 or 65). Not real sure on the specifics as it was a long time ago.

In your application, the most important thing, aside from strength, is balance.

not real sure of exact part you want to weld. but we use to do alot of that type thing. except we would use a lath to turn the repair part back to concentric and straight. i'm guessing that if the part has any wobble at all, it will wipe out any bearings/seals nearby. if not then there's fatigue that will break any repaired part that is not true. we would turn a new shaft with a taper (for weld penetration) and leave a small dia. at one end. this would be pressed fitted into a hole drilled in the mate part. then weld up above the final diameter. then turn down on the lath. clear as mud?

The shaft is the smaller of the two shafts that slips inside each other and it is broken at the point where the smaller shaft is attached to the coupler with universal that is connected to the gear housing on top of the mower.(Not the shaft that is attachable at the tractor PTO.) I get your point about vibration so welding will need to be very exact. Thanks for the reply.

bare with me, i'm kinda slow. is it the slip joint of the pto shaft, maybe a rectangular male and female tube? if so and the male is long enough, you may be able to remove the broken piece by grinding away welds and driving part out. then pressing remaining drive rod back into the yoke and rewelding. the yokes have to be install as orginial (not turned 90 degree) or the pair will not form a constant velocity joint. have to appologise, my mind doesnot work with out pictures.
