Little JD jigger. Hi, Superwrench0166. That little jigger looks like a JD MC dozer, somewhere around the 40 hp class, I think. A nice tidy machine. Thanks for sharing.
Some friends of mine have one like that but no wheres the same condition. They used it to clear off a lot on the family property for a new home. Worked well for grading "all sand" and for pulling stumps. Shortly after the lot was done the engine seized, the engine was rebuilt this past winter and is up and running again.
