I have finally found me an engine for a project garden tractor I am working on. It is a D662 that was imported by a guy who gets them in a container. It has a tach drive on the front of the gear housing. I would like to put it to use and add a mechanical tachometer. Anybody have any idea what drive ratio this would be? Were there Kubotas that had a tach that would work? I have seen a couple online that looked interesting. The guy I got the engine from mentioned something about possibly using parts from a motorcycle to adapt a tach. Anyone heard of that? Lots of questions, I know, but surely someone here has been through this...maybe. Thanks!
