Lawn Mowers and engines can have a series number and a model number. The series number is normally what is displayed on the side of the mower, like LT1000, DYT4000, LT1042 these are not model numbers. These series numbers are the same as a F150 is a series number for a Ford Truck, they are made for years and years with different parts. A 1980 F150 is not going to use the same parts as a 2018 F150, Same as mowers a GTH2654 made 10 years ago is going to use different parts than a GXH2654 made last year. Sometimes you may get lucky and your items will match up, if we list a series number it is so you can research the listing and match up the parts. This series number is not a good number to use for finding parts for your mower. Your mower will have a model number or a product id, normally this is found under the seat or on the back of the machine. It may have numbers and letters or just numbers, this number will identify the exact parts for your mower. Most of these model numbers can be searched for online and a parts breakdown will be available to check your part numbers.
All units will have a model and serial number, on some lawn mowers, the engine and the mower are two separate parts and each will have a model number. If you are looking for engine parts, you will need the engine model number, if you are looking for mower parts, you will need the mower model number.
