How to Decode MTD Model Numbers

It is important to locate your model number on an MTD product in order to secure the correct parts when you need them. MTD manufactures a full line of lawn and garden products for homeowners. Older model serial numbers have six or seven characters and current models have 11 characters. MTD Products describes a character as a number, a letter or a dash.

Observe your MTD product to find the model and serial number sticker or plate. It is about 2 inches by 3 inches in size.

Look on the rear deck of a walk-behind mower and the rear frame on a chipper-shredder or edger. Lift up the seat on a riding mower and look under it. Tillers and cultivators have the plate on the engine housing above the tines.

Observe the plastic area near the recoil starter on a leaf blower. The leaf blower sticker is smaller than other products.

Six or Seven Character Model Numbers

...

Read the first character of the model number. The number 1 is a general category of lawn mowers of all types.

Look at the second character, which will represent the type of mower or accessory. The number 1 is a push mower, 2 is a self-propelled mower, 3 is a lawn tractor, 4 is a garden tractor, 5 is a reel mower, 8 is an electric mower and 9 is an accessory for a lawn mower.

...

Read the third character to decode the year your product was manufactured. A zero indicates a year that ends in a zero. A 1 is a year ending in a 1, and so on through all of the numbers in this position. Read the last characters in the model number for the decade of manufacturing. If there is no letter at the end, it is between 1964 and 1973, an A is 1979 to 1983 and 000 is 1984 to present.

Write down the digits after the dash and before the letter on the end, if your model has one. This is your model number of your product that is needed for parts ordering.

A zero can be 2000 or 2010 for the year.
