I have a nice Barely Used Skid Steer mount . It was on a John Deere 420 Loader.
So, it's 4 pin to the Loader and then of course you have the Skid Steer/ Euro mounting. It will fit most Compact Tractor loader Arms. I was gonna put it on my International but then I changed it to John Deere QT because I have an 870 and 1050 with extra attachments laying around.
