Lift up the seat on the Cub Cadet mower to reveal a rectangular model plate. The top of the model plate should have an 11-digit model number and an 11-digit serial number. Write both of these numbers down on a sheet of paper. Look on the deck or rear door of the discharge unit on push mowers.
Open your favorite Web browser and go to the Cub Cadet Online Manual page at manuals.mtdproducts.com/mtd/Public.do?
Type in either the model number or serial number in the designated box and click "Search."
Click the link to see the manual for your particular model. The year will be listed in the manual.
