Nice find on the 123!! Sweet score. You can't use the hydro for a hydraulic lift because the hydro wouldn't be ported. The 123 could have a hydraulic lift added. They bolt on the right side of the tractor and run off the back of the motor. I suppose one could add a ported hydro to the 123, but it would take alot of modifying to get everything to work. I agree with Lew, got any pics of the tiller and disc????
