What is this

[Surken]

One of my neighbors has a huge disk plow and has said I could have it... it was originally used as a "pull behind".... anyhow, to make the story shorter, the disk comes in two pieces and is connected by something similiar to what is shown in the picture.... The ball is affixed to the first section and the behind section is attached similiar to a bumper hitch... will have to inspect it closer next weekend...

Thank you all for the ideas. I will see if I can get some dimensions. Right now the part is at the farmers machinery museum, http://www.bcfma.com/ but I can go and take some other pictures. Maybe Dougster will have something next weekend.

I have some new info. The part is about 8 inches long and the square hole at the end is about three quarter of an inch. It has a serial number 404R1 and a part name Vapor. I hope someone might know what it is. There used to be a railway parts manufacturer by the name of Vapor. It might still exist in the east of Canada.
Good luck Surken.

My guess is a ball for a sicklebar mower and it articulated a bit at the joint as it went around. I don't think that part connected directly to the PTO rather the other end of the pitman arm where it connected to the sickle.

Thank you Shinnlinger. I think you are on the right track, although someone told me it is a double female universal joint for a three quarter socket set. With other words we are still not sure what it is.
