The MTD numbering system is based on a 6 digit number. Private label or Customer model numbers are 9 digits.
The last three numbers (Customer designation) indicate that something is different from the basic MTD number
designated by the first 6 digits. The difference may be only the color or it may have different wheels, handles,
shrouds, etc. Generally, the push and self-propelled mowers have more variations than the lawn tractors, garden
tractors and tillers.

In 1984 because of computer programming the letter code was dropped and ‘000’ was added to designate
the customer.
