C pto spline adaptor

Hi About 2 years ago we put a 3 point hitch on our 42 C and it has made it a lot more usefull. In our family we have 4 different places and we all lend each other attachments. My brother has a 4 foot tiller that I would like to try on the C but I have the 1 1/8 pto his tiller is set up for 1 3/8 with a snap pin coupler. I have seen the various adaptors on the market and like the one my local New Holland dealer has it looks like it will only increase the length of my pto 1/4 of an inch and it has the groove for the snap pin yoke on it, I looked at a plain adapter sleeve and it didn't have the groove on it. How do these attach so that they dont come flying off? I thought about drilling the adaptor and using some loctite bearing mount and a roll pin, I plan to leave this on the tractor permanently so I think I will check the bearing and replace the seal before I do this because I dont think it will be to easy to get this adaptor off once I install it this way. Thanks for any input on this, T.J.

I have one on my B and it's held on by a bolt. The bolt works fine since the adapter is splined on the inside to match the splines on the PTO shaft. Your idea of the roll pin should work great. You won't need anything on the inside of the adapter except some anti-seize compound to keep it from becoming permanently stuck to the PTO shaft. You may want to change that seal again in 10 or 15 more years. :o)

Phil I was at tractor supply today and the one they sell comes with a roll pin so I picked one up. Let you know how it works out. T.J.

Do you need to drill a hole in the shaft, to put a pin or bolt threw it? Does that weaken the smaller shaft?

The shafts on my B and RC both had the holes in them already. I haven't checked any of my red tractors to see if the holes are in them too.

Today's Featured Article - Harvestin Hay: The Early Years (Part 2) - by Pat Browning. The summer of 1950 was the start of a new era in farming for our family. I was thirteen, and Kathy (my oldest sister) was seven. At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th ... [Read Article]
