HRS216 model and serial number locations
HRR216 and HRT216 model and serial number locations

Once you know your basic model (such as HRS216, HRT216, HRR216), you need to know which model type you have. These are the model number suffixes like PDA, SDA, and VXA. 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. 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 HRR216 is replaced by the HRR216K1 which is replaced by the HRR216K2, 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. 

Pages we have completed will have highlighted links. Model series are vaguely arranged in the order their series were first introduced, from earliest to latest. All dates are approximate. You can use the following links to skip down to the appropriate portion of the page.

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.
