Serial number posted is not a Hustler serial but is a MTD serial 1B010H20162 with a year of manufacture ending in Zero.
You need to contact MTD dealer to see if they locate brand and model it is from the serial. Don't know if they even have access to such info. MTD is pretty darn secretive about things
This will get you closer but you will need to do a little IPL comparison from here. From the serial number it would be a 2000 model built. Knowing the deck size you down to the 2000 yr model number but not the exact 11 character model number.
