It's called a double cardian joint. It uses two u-joints with a ball and socket joint between them. Lots of equipment went to that style at the tractor end years ago. It allows more flex than a single joint. They also use them on pickup driveshafts. You see them on the front propshaft on 4X4 Chevy's and the rear shaft on some S-10's. They are expensive.

Yep, much more flex angle than a regular u joint. Us lifted jeep guys use them along with a slip yoke eliminator kit on the t case.

The one Jon uses is special with an extra i in it :biggrin2:

In other words you can turn some tight corners without being afraid you are going to rip something apart, got it!:beerchug: We have a tow type bushog with a really long driveshaft--it tells YOU how short you can turn. So, in ag areas, did this replace the short shaft/bearing support that is common on hay balers?

That is true, Jeeps use them also. :beerchug:

I didn't even realize I spelled it wrong. Good catch! :RedFace2:


We had an old 13' Bush Hog pull type also with that long shaft. It was a pain.... and after the rear joint broke a couple times and that long shaft went whipping around, we cut the tongue off and made it a 3pt mower. :biggrin2: Short shaft was much better!

Well, the joint didn't replace the short shaft... it actually made them shorter. You find them on almost everything now, including balers. :beerchug:
