Shibaura make alot larger mowers and tractors . The reason its still working is Ford did not touch the design . Shibaura and Kubota are big competitors thru out asia and Pacific regions . Once you have mowed with a diesel you will never have a gas again ever.
I would NOT use it full time, this should be a collector tractor used a few times a year, it would bring good money to collectors, and believe me there's plenty of them. It is too good for daily wear & tare!
I believe it is a double belt that runs direct off the engine located either right behind the grill or a black plate directly below the hood/grill area. It is a simple tension style engagement setup that may need to be adjusted tighter or the belts replaced. This setup in turn drives the shaft going to the deck.
