A B/S Vanguard or Kohler Command would make a nice swap I would think. Don't know how much work it would be though...

My 720 has been re-powered with a gas 23 hp B/S engine, it works very well.

Might try to contact Larry Karg at orangespectacular.com. He has done some innovative engine swaps and extensions on this tractor size.

If the frame is extended, what about the hood?

Larry Karge's 720 was at Hickory Corners approx ten years ago; it looked professional. That was before I became interested in 720's, now wish I had pursued details.
