Cub Cadet Snow Blower Model 31AH54ST756

Locating Your Model and Serial Numbers

The model and serial numbers are essential to find correct MTD® genuine factory replacement part numbers for your outdoor power equipment. Once you know these numbers, you can use either the illustrated parts look-up tool or the operator's manual download to easily search for the correct part numbers needed.

What should my model and serial number look like?

MTD's current (1997 and later) model and serial numbers are generally 11 characters in length. A character could be a number, dash or a letter. If 0 represented all numbers and/or dashes and X represented all letters, the model and serial numbers should appear as follows: 00XX000X000.

These are made of both letters and numbers, and typically look like this: 11AA111A111.

Where do I find the model and serial number tags?

Identification tags are located in areas unlikely to need replacement - even after years of use. For most of our power equipment, these tags are approximately 2" x 3" in size. They also have the MTD product's name, address and customer service phone number listed across the bottom.

How do I determine my product model number and/or serial number if the tag is missing or illegible?

If a product identification tag has been rendered illegible, or the numbers are not valid within our online support systems, it will be necessary to call in and speak directly with a Technical Support Agent for assistance in properly identifying these products.

Our Technical Support Department staff may be reached at 1-800-668-1238, Monday thru Friday from 8:00 a.m. to 5:00 p.m. EST. The technicians there will ask you a number of questions while researching our historical manufacturing archives in an effort to determine the model number and manufacturing data of the product. This research can often be a daunting task and may even involve submission of photographs or measurement of particular parts that will identify a production series.

We cannot complete this identification process over the Internet because of its complex nature and the need for direct conversation while researching.

Once the model number and manufacturing data are properly identified, we suggest writing the number in the Owner's Manual so it is readily available. You could also write it on the product with an indelible marker or an engraving tool.
