Hi Mark,
Welcome to the forum! Are all the wheels driven? The hub on the center wheel makes me think it might be an idler and not driven. Is the machine meant to be used without the tracks? Looks like a nice machine, but I've never seen one before. Maybe someone else can shed some light on it. There are a lot of knowledgeable people here.

The center wheels are not driven, the tracks can come off but it seems to do a lot better with the tracks on.

Thanks,
Mark
