Most are 3600 rpm or 60hz. Be aware if you get it set up with belts at the correct RPM/HZ and the genset is under load it may slip bringing the HZ down with it. Could damage the genset.
Replacing the engine isn’t an option?

It would seem you have nothing to loose by trying it.. As long as you don't cut the frame for the engine mounts or such so that if it doesn't work you can replace the engine..

Here is info from tractordata.com

It shows 29 engine hp, but doesn't show hp available to the pto.. It would seem the worst that could happen is you can't run a long heavy duty cycle on the generator at near maximum amperage.. Meaning, maybe short welds with lighter rod ??

PLEASE be sure to post how it works....
Good luck.

Our tractors do have governors, but they don't have the same characteristics as power generation governors. A generator has very little speed droop from no load to full load so that its frequency change is low. Our tractors have more droop, so wouldn't have good frequency control over the full load range. However, if the generator's load was a small fraction of a tractor's rating, it could give acceptable results.
The OP mentioned both welder and generator with the primary function being welding. I doubt that frequency is critical while welding.

I would like to thank everyone who replied to my post. I believe I will scrap this project and look for a real PTO driven generator. If anyone here would like this welder to proceed with a new engine installation it will be free of charge to you. Thanks again!
