Remember those old lawn mowers that propelled themselves by engaging the tread of the front wheels?
If someone is wanting to refurbish one of those I have new Drive-Pinions. The first thing to get thrown away was the cover. I have one of those still wrapped in plastic. Two of the pinions are 3" dia. x 2 1/4" wide with 1/2" center dia. part #352890. Two are 3" dia. x 2 1/4" with 5/8" center dia. part #253851. Two in the package are 2 3/4" dia. x 2" with 5/8" center dia. part #420066'
It is probably a long shot that anyone would restore one of those, but if so I'll have them set back for a while. Rick
