I have a Dearborn PTO Extension Kit that I am wanting to repurpose to drive a Transmix cement mixer. I have the Mixer's drive cylinder mounted to the PTO extension on the 1 3/8" shaft then I discovered that the drive end of the extension kit that connects to the tractor is an 1 1/8" PTO Shaft. My Plans are to mount the mixer on my 8N that has an 1 3/8" PTO Shaft. What are my options? Does anyone have a Dearborn PTO Extension kit that is 1 3/8 on both ends? Can I install an 1 1/8" PTO shaft in my 8N? (Not my preference).
