So I have an old Shubara tiller I am trying to hookup to my Kubota L2350DT. I have converted the hitch to a 3 point style hitch, but still lack the PTO shaft. The old PTO is way to short, and I have had no luck finding a 1"-13 spline PTO drive shaft to fit the tiller output shaft. My latest plan was to take an extra PTO shaft I have, and change the implement end yoke with the one that fits the tiller. However, today I have discovered that the tiller yoke is a series 2 and my extra drive shaft is a series 3, and so the cross bearings are different sizes. Is my best alternative to buy a new series 2 PTO shaft and swap the implement end yoke or is there another choice I am not seeing?
