The lower lift arm, RH side, sitting in the seat, the ball end (not draw bar end) has busted open.

The lift arm has a removable ball on the tractor end and a cat II on the draw bar end. Having trouble finding a lift arm that

fits over the ball end. Anybody have a part # and good source? The lift arms I am finding do not have the open hole to fit over ball on tractor end

Center to Center length on mine is approx 32 5/8"

Yep, I'd buy a weld on end and repair the arm. If you aren't handy that way, take it to a welding shop.

I no longer have a welder and broke the end off of one of my lift arms. A half hour of the hourly rate at the local welder fixed me up. $25 or $30 bucks, something like that. In your case you’d need a new ball end as ovrszd mentioned.

And they are cheap and easy to find at any farm store.

Just make sure it's the same length as the other lift arm if you repair it.

Should not be hard for the welder if he measures the broken one. Maybe take both arms in if worried. We are just talking about cutting off the old end and welding on one of these. This repair with the ball end should be under $100. Under $30 if you weld.

OK I finally got this lift arm straight in my head...I somehow thought the ball end on the tractor was permanent....never mind.

Anyway...to your point about removing the ball on the tractor end to replace the new welded on lift arm end. Nut came off nicely but the 'pin' itself is being stubborn. I've got the 'flat' end of the pin which is not budging....any advice before I get too aggressive with it?

Thanks

Penetrating oil and if needed use a torch to try to get expansion to break it free. I would put the nut back on 90% to protect the threads before whacking on the end of it.
