What to Look for in a Petrol Mower Under £350
Before diving into the models, let’s quickly cover what you should look for when choosing the best petrol mower for your needs:
- Weight: A lightweight petrol mower is easy to handle but does reduce build quality. Heavier models tend to be built from higher quality components.
Engine Power: A minimum of 125cc is ideal for most small to medium gardens. Higher engine capacities can handle denser grass and tougher terrains.
Cutting Width: Mowers with a 40–46cm cutting width strike a good balance between performance and maneuverability.
Self-Propulsion: For larger gardens or sloped areas, a self-propelled mower can save you time and effort.
Build Quality: A solid frame is crucial for durability, and steel decks tend to last longer than plastic.
Mowing Options: Grass Collecting options are normally preferred but having the ability to Mulch or Side Discharge can be hugely beneficial.
With that in mind, let’s look at the best petrol lawn mowers on the UK market for under £350:

Tips for Choosing the Right Petrol Mower Under £350
Garden Size: For larger gardens or uneven terrain, a self-propelled mower can be a huge help. For smaller gardens, a push mower with a lightweight design might be all you need.
Power Needs: If your lawn has thick grass or hilly areas, look for a mower with a more powerful engine (over 130cc).
Mowing Frequency: For regular mowing, a mower with a larger grass collection bag (55 litres or more) or a Mulch System will save you time. It also means fewer stops to empty the bag.
Build and Storage: Steel decks are great for durability, but if weight is an issue, consider a mower with a lighter plastic deck or foldable handles for compact storage.
