Hmm... there doesn't seem to be a local Hatz dealer here! But I see on their website that an "Italian" PTO shaft is an option. The most likely route of acquiring one though is going to be from some broken construction equipment. It does look nice though-- that they have low noise and vibration.
This is one of the big differences I see with my other Goldoni with the 3LD510 Lombardini diesel vs this one with the gas motor. The gas motor is so much quieter!
My other idea had been, to get the propane motor for the Goldoni with the powered trailer that now I no longer need to detach, and use its diesel motor on the Goldoni for rotovating and rotary plowing, even grass mowing.
But now I'm just happy that the motor is working, and yesterday I got some beds in the garden prepared, next week with the rotary plow we'll be planting potatoes...
