Honda Model Number and Serial Number Locations
Model numbers and serial numbers can mean the difference between getting the right part and the wring one. For most Honda equipment, the base model number is on the starter cover, the engine cowling or another prominent location on the frame. The serial numbers are a little more difficult to find. Honda equipment generally has a serial number for the frame, and one for the engine.
In addition to the regular model designation, there are variations in model number such as K0, K1, K2, etc. These represent design changes made in the product line from time to time. The changes may be cosmetic or mechanical, but are not enough to warrant a completely new model designation. Many parts change from one version to the other, so it is usually necessary to determine which version you have. Serial numbers are the most reliable way of doing this. This page is not complete for all models and probably never will be, but it covers some of the most common questions.

Engines
When working on Honda engines, only one serial number is required, but other information
may be necessary, such as carburetor or type number. For serial number location
diagrams, please refer to our Honda
engine parts section. We have diagrams for nearly all models of Honda
general purpose engines.

Honda
Lawnmowers
On Honda lawnmowers, the model numbers and serial numbers are usually located on
the back of the deck between the handles. For some models, there are two number locations
near where each side of the handle meets the deck, one giving the model designation, and
one the serial number.
Honda Riders and
Tractors
On Honda riders and tractors, the serial numbers are usually located on the side of
the frame. Decks, catchers, and blowers also have their own model and serial numbers.

Honda Tillers
Honda tillers generally have the frame serial number either on the handle, or near
where it connects to the main chassis.

Honda
Generators and Pumps
Most new models have both engine and frame serial numbers, but some of the older models just had one serial number. Every model is a little different. You may have
to do some hunting.
