How To Find Your Lawnmower Model and Serial Number

When finding lawnmower parts or booking a service, it's crucial to know the model number and serial number of your lawnmower. In most cases the model and serial number are clearly displayed somewhere on the lawnmower, but the location differs between manufacturers.

This short guide will help you identify where to find the model and serial number of your lawnmower, including handy pictures. We've also included example model and serial numbers for several manufacturers to make this even easier.

Why finding your model and serial number is important

When your lawnmower has a problem, ordering the correct parts the first time will allow you to get back up and running as quickly and hassle free as possible. With your model and serial number to hand, the task of identifying the parts you need becomes much easier.


If you can't find the identification plate

It may be possible for us to work out your model number by looking at other aspects of the machine, but without the exact details from your mower it becomes much more difficult to identify the parts you need.

The same model from different years aren't guaranteed to use the exact same parts. This is down to manufacturers investing in product development to increase quality, improve performance or reduce costs - meaning parts will change over time.

If your identification plate is either missing or damaged and no longer legible, we will do our best to help you.

Please send us as much information about your lawnmower as possible, as well as some clear photographs. This will give us the best opportunity to identify your machine and allow you to select the parts you need the first time round. Please email spares@fgadamsonandson.co.uk.

Don't confuse your lawnmower with your engine

If you have a petrol mower, it's important to understand that your engine may be a different make to your lawnmower. For example, certain Hayter lawnmowers used Briggs & Stratton engines, and some Mountfield lawnmowers used Honda engines.

If it's an engine part you need, such as a gasket or fuel system part, making sure to find the model and serial number of your engine will help you find the parts you need.
