Greetings ILENGINE!
Thank you for researching my Model number, and for explaining the D.O.M. entry breakdown.
I likewise wanted to better understand the breakdown of the Model number, if you have the time to explain it a little bit further. I've done some research on other threads and think I think that I have managed to fill in a few of the blanks in the equation:
The 2000 MTD Yard Machines model appears to be:
13A 6672 G129*
This is based on the following breakdown:
1 = Lawn Mower
3 = Ride-on (Lawn Tractor)
A = Sales Level Indicator
6 = Engine number or letter
6 = Frame size
7 = Transmission Type / Number of Speeds
2 = Hood style
G = 42" Mower Deck Size
1 = ? \
2 = ? > Customer Number ?
9 = ? /
How badly did I do?
Thank you again for your time and assistance in this endeavor, it is sincerely appreciated!
