Finding Model and Serial Numbers:
Older (Pre-1995) Models

On most Honda lawnmowers made prior to 1995, it's a little difficult to determine your precise model number. The model ID tag (right) may have something like HR214-CF, HRA214-DL, HR215-EF, HRM215-OL, HRB215-FJ, etc. In such cases, the last two letters in the silver box are not part of your model number. We repeat, those last two letters on the model tag are not part of the model number. We've been selling Honda lawnmowers for over 30 years and still have no idea what those last two letters mean. 

Once you know your basic model (such as HR21, HR214, HRM215) found on the shroud, you need to know which model type you have. These are the model number suffixes like PDA, HXA, and SMA. If your model number tag doesn't give you a complete model number, Look on the front of the deck near the muffler. You should see a PX, PD, (push models) SD, SX, HX, TD (self-propelled models) or something similar. These tell about some of the features of the mower and are part of your model number. The A means that the mower was made for the American market. Since all of these models are for the American market, the final A is implied. If your mower is where you can't look at it right now, you might be able to pick it out by comparing the features with the models listed below. Here's what these extra letters in the model number suffix mean (At least since 1985):

You will also need to know which version you have. Honda may make small changes in a model from time to time. The new version will have approximately the same specifications as the previous one, so it's not given a new model number. Instead, Honda gives it a new K number. The HRM215 is replaced by the HRM215K1 which is replaced by the HRM215K2, and so on. Some of the changes are obvious, but some are not. The most reliable way to tell which K number your mower has is by using the frame serial number, usually located on the deck near where the handles are connected. Where needed, we list the serial number ranges for the different versions below. 

Key
S/P = Self-Propelled
BBC = Blade Brake-Clutch - Only the blade stops when handle is released.
Zone = Zone Start (Flywheel Brake) - Engine stops when handle is released.
E/S = Electric Start
Cast = Cast Aluminum Deck Construction 
Steel = Steel (Sheet Metal) Deck Construction
Poly = Polymer (Plastic) Deck Construction
