The MTD numbering system is based on a 6 digit number. Private label or customer model number 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 only be a label or color or it may have different
wheels, handled shrouds, etc. Generally, the push and self-propelled mowers have more variations than the
lawn tractors, garden tractors and tillers.
