Why do they put that divider in the bucket. It seems the really old machines have that. But this is the second time I've seen this on a case backhoe. This is a 580B.
Case-IH Farmall 45A, Kubota M8540 Narrow, New Holland TN 65, Bobcat 331, Ford 1920, 1952 John Deere M, Allis Chalmers B, Bombardier Traxter XT, Massey Harris 81RC and a John Deere 3300 combine, Cub Cadet GT1554
Here's another pic. of a 580B on sale at ebay.com. I didn't realize how small in length the cab is. No wonder why I seem to lean toward the 580C's. More roomy!
