This is the carburetor from a Kawasaki FH721v engine in a John Deere X 500 tractor.
This tractor had less than 40 Hours before it was parted out. The problem with the tractor is/was a very minor oil leak between the block parting lines. The leak was barely enough to attract dust but was enough to annoy the customer. Engine ran perfectly when parted. Another customer needed a hood, and the trans was pulled from it to repair a used tractor. so apart it all came.
