Need help finding your Simplicity model number?
The Model Tag for your Walk-Behind Mower will usually be found on the rear top left side of the deck, on the top of the unit near the engine housing, or on the back of the deck, underneath the debris (“trailing”) shield. In cases where the mower and the engine were made by the same company, you may have just one Model Tag, found on the side of the engine shroud next to the recoil housing or on the side of the engine housing.
We strongly suggest taking pictures of your Model Tags or writing the information on your Parts Manual for reference with future repairs. As always, please feel free to call or email us if you need any help locating the Model Tags for your equipment or engine.
