Thanks for the updates. The shaft on the King Kutter is also 1 3/8" diameter so I think that must be a standard or the PTO shafts wouldn't be interchangeable between brands. I checked at NAPA this morning and the largest in their kit was 1 1/4". I'll check at the JD and Kubota dealers on Monday since they started closing on weekends due to the corona virus. TractorGuy, thanks for the link. If I can't find it at a dealer Monday I'll order a package from them. I noticed that the price is much better than ordering it from King Kutter or Rural King. They want over $7 online for one where as on the site you provided it's under $8 for a package of 25. I have also toyed with the idea of just converting it to a slip clutch and be done with it. But I keep wondering if it's worth $132 plus shipping when I only mow maybe 3 times a year Have a great weekend........Don
