I have a 278 Bush Hog mower and exploded the U joint and sprung tractor yoke. Dealer with parts manual pulled out a yoke but it didn't match what I had, so maybe pto shaft was replaced. I finally found a yoke at Tractor Supply but after 9 stops I can't find the U joint. Yoke I got is metric. My imperial (inch) measurements of the U joint: cap diameter is 1.06 and width across is 2.94. Is there an internet source that I take the dimensions to and get a joint? Thanks.
