I just wanted to let everyone know the conclusion to this story. I was not able to get any replacement parts from Rhino. I was told the mower was built between 1964 and 1979. I checked a couple of local Rhino dealers with no luck either.
So, I decided to convert this thing to a shear pin set-up. I went to Tractor Supply and picked up a new PTO shaft and a hand full of 1/2" bolts. Yesterday I got out there with my angle grinder and drill press and got busy. I was able to set the drill press directly on top of the shaft and drilled a 1/2" hole in it. Then I cut off the necked down section leaving only the 1 3/8" diameter shaft. Or at least I thought it was 1 3/8" diameter. It was just a hair bigger than that and wouldn't fit inside the new PTO shaft connection. Spent the next hour or so grinding the outside of the shaft down to fit. I finally got it and the PTO shaft spins nicely on the shaft. I stuck a bolt in the hole, hooked everything up, and jumped on the tractor. I took it out back and did some brush hogging for about half an hour. Everyting is working great! I even tested the shear pin/bolt and got it to snap on a 3" tallow stump.
I want to thank everyone for their input and help with my problem.
Happy Hoggin!
