I bought a Cub Cadet 2185 from a neighbor. Shows 477 on the hour meter. Has a three blade deck. Has no identifying information, tag has been removed. Neighbor had the tractor for several years and I am sure is unaware of the missing tag. These tractors were manufactured 1994 to 1999. Were there any major design differences during that time, and how can I tell which (year) model I have? The immediate need is for a blade for the deck. I am having difficult time identifying the deck as it is 3 bladed and supposedly 2185 didn't come with 3 bladed deck. I'll attach a picture of the deck. Thanks for the help!
