Locate the small, black, metal plate that contains the model and serial numbers on your Husqvarna. On chain saws, blowers and trimmers, the plate is typically found on or near the plastic casing in a corner near the recoil starter. On mowers and tractors, it is located near the engine block or mower deck.
Copy down the two sets of numbers on a piece of paper. The top set of numbers is the product or model number. The bottom set of numbers is the serial number.
Call Husqvarna customer service at (800) 487-5951 and relay the model and serial numbers to the representative. He should be able to help you pinpoint the year of your Husqvarna product.
