My neighbor called me about an issue with his series IV D17. We are both in the middle of making hay. He went to engage the pto lever to run his Tedder and the shift lever came off in his hand. I looked at it and it just broke loose at the weld where it attaches to the shaft. Anyone have this issue before? My service manual only covers my series I. Looked in parts book, and it appears to be a spring pin that holds that shaft in place. Can I access that from the PD side cover so I can remove the shaft to weld the handle back on? I have replaced the o-rings on my PD shaft on both sides and recall seeing the pto shifter behind the PD but don’t know if I can get to the spring pin to drive it out?

Open the hole a bit and clean off all paint and oil and weld it back on the best you can Cooling it with a garden hose may save the Oring so it doesn't leak. The old D17's had a roll pin. A series 4 has a solid pin that drives out hard. This has been discussed before but I would weld it and make hay for now.

Ours broke 30 years ago. My dad had a guy weld it as DrAllis describes and works to this day. 10 years ago the o-ring started leaking a bit of oil so I split it and replaced the o-ring.

This is a "one-shot" deal. Make sure the welder is plenty hot enough and everything is CLEAN.

crank up some 3/32 5p plus cap with 3/32 7018 with a air nozzle blowing behind it, its a small weld but it has to get in

Thanks, had thought about that but was hoping to be able to access it without a split. I will give it a shot. Thanks everyone. It will have to be a better welder than I am.
