Need help finding your Lawn-Boy model number?
The Model Tag for your Chainsaw will usually be found on a metal plate in one of three locations: beneath the handle on the clutch side, above or below the oil fill cap, or in front of the clutch at the bottom, below the bar nuts. Occasionally the Model Tag maybe on the right 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.
