The baby moons were available as add options from 1964-1968, and as stated above, were identical to the early Cub Cadet and early Wheel Horse hubcaps. In 1967 John Deere started to personalize theirs, by adding the center ring on the caps. These center rings were trimmed with white paint, and were available for all tractors up through 1991 I believe. In 1992 the same caps were available, but they didn't have the white paint around the ring. The hubcaps are very collectible, and highly sought after pieces.
John Deere hubcpas were available for all lawn and garden tractors, and could even be installed on some attachments such as dump carts, pull behind sprayers, etc.. They are nice accessories, but are very expensive when you find good ones. Most of the ones found on ebay are either very rusty, dented, or both. There are some guys out there, selling NOS
sets, but again, be prepared to pay as much as $250.00 for a set.
Standard sizes for the round fender tractors are 8" caps for the fronts, and 12" caps for the rears.
Good Luck to you and Happy Hunting!
