What to Look for in a Budget Petrol Mower
When you are shopping for a petrol lawn mower under £100, you are looking at entry-level models. The key specs to check are engine power (usually 1250W to 1300W), cutting width (30cm to 33cm), and grass bag capacity (20L to 35L). Most budget mowers use a two-stroke engine, which requires a mix of oil and fuel. Check the fuel tank size, as smaller tanks mean more refills. Also, look for a mower with a handle that folds for storage, as space is often tight in smaller gardens.
Mistakes to Avoid When Buying Cheap Petrol Mowers
One common mistake is buying a mower with a very small grass bag. A 20L bag will fill up fast, especially if the grass is damp. Another mistake is ignoring the warranty. Budget mowers often have a 1-year warranty, but some brands offer 2 years. Also, do not assume that a higher wattage always means better performance. The blade design and deck shape matter just as much. Finally, check the weight. A mower over 15kg can be hard to push on uneven ground.
Draper 1300W 32cm Petrol Lawn Mower
Best OverallPros
- Reliable 1300W engine starts easily
- 30L bag is decent for a budget model
- Folding handle for easy storage
Cons
- Plastic deck may not last as long as steel
- No mulching function included
The Draper 1300W is our top pick for a petrol mower under £100. It has a 32cm cutting width, which is good for small to medium lawns. The 30-litre grass bag is larger than many competitors, so you will not need to empty it as often. Owner reviews highlight that the engine is reliable and starts on the first or second pull, which is a common issue with budget mowers.
Build quality is acceptable for the price. The deck is plastic, which keeps the weight down to 12.5kg, making it easy to manoeuvre. The handle folds, which helps with storage. Some owners note that the cut quality is not as clean as more expensive models, but for the price, it is very good value. The warranty is 1 year, which is standard for this price bracket.
Hyundai HYLM3200
Value PickPros
- Similar spec to Draper at a lower price
- Decent 30L grass bag
- Easy to start
Cons
- Plastic deck feels less durable
- Some owners report vibration
The Hyundai HYLM3200 is a strong contender if you want to save a little money. It has the same 32cm cutting width and 30L grass bag as the Draper. The 1300W engine is comparable, and most owners say it starts reliably. It is a good choice for a small lawn where you do not need a lot of extra features.
Build quality is basic. The deck is plastic, and some owners mention that the mower vibrates more than expected. The cut quality is acceptable for the price, but it may struggle with very thick grass. The handle does not fold as flat as some competitors, which could be an issue for storage. Hyundai offers a 2-year warranty, which is better than most at this price.
Bosch Rotak 32
Electric AlternativePros
- Lighter than petrol models
- Excellent cut quality
- Large 31L grass bag
Cons
- Requires a power cable
- Not suitable for large lawns
If you are open to an electric mower, the Bosch Rotak 32 is a top choice. It is corded, so you need a long extension lead, but it is much lighter than petrol models at only 9.5kg. The 32cm cutting width and 31L grass bag are similar to the petrol options. Bosch is known for reliable motors and good cut quality.
Owner reviews are very positive. The Rotak 32 cuts cleanly and is easy to push. The grass bag is large and easy to empty. The main downside is the cable, which can be a hassle if you have a garden with obstacles. It is not suitable for lawns over 300 square metres due to the cable length. Build quality is excellent for the price.
Flymo Turbo Compact 330
LightweightPros
- Very light at 8.5kg
- 33cm cut width for a compact mower
- Easy to store
Cons
- Small 25L grass bag
- Plastic deck may crack over time
The Flymo Turbo Compact 330 is one of the lightest mowers you can buy. At only 8.5kg, it is easy to push and carry. It has a 33cm cutting width, which is wider than many budget mowers. The 25L grass bag is smaller, but the mower is designed for small lawns. It is an electric corded model, so you need a power source nearby.
Owner reviews are generally positive. The mower cuts well for its size and is very manoeuvrable. The plastic deck is lightweight but some owners report it can crack if hit against a hard surface. The grass bag fills up quickly, especially in damp grass. Flymo is a well-known brand in the UK, and parts are easy to find.
Mountfield 30cm Petrol Lawn Mower
Small LawnsPros
- Compact and easy to store
- Reliable Mountfield engine
- Good for very small lawns
Cons
- Small 30cm cut width
- 25L bag fills quickly
The Mountfield 30cm petrol mower is a compact option for very small lawns. It has a 1250W engine and a 30cm cutting width. The 25L grass bag is on the small side, but it is fine for a lawn under 150 square metres. Mountfield is a well-known brand in the UK, and this mower is built to a reasonable standard for the price.
Owner reviews mention that the mower starts reliably and cuts well for its size. The build quality is acceptable, with a plastic deck that keeps the weight down to 11kg. Some owners note that the cut quality is not as good as larger models, and the small bag means more trips to the compost heap. It is a solid choice if you have a very small garden and want a petrol engine.
What to Check Before Buying a Petrol Mower Under £100
First, measure your lawn. A 30cm to 32cm cut width is fine for lawns up to 200 square metres. For larger lawns, you will need a wider cut, but those mowers cost more. Second, check the engine type. Two-stroke engines are common at this price, but they require mixing oil and fuel. Some models have a four-stroke engine, which is easier to maintain. Third, look at the grass bag. A 30L bag is better than a 20L bag. Fourth, check the height adjustment. Most budget mowers have 3 to 5 height settings. Finally, consider the warranty. A 2-year warranty is better than 1 year.
Mistakes to Avoid
Do not buy a mower with a very small grass bag. You will spend more time emptying it than mowing. Do not ignore the weight. A mower over 15kg is hard to push on slopes. Do not assume that all petrol mowers are the same. Some have better blade designs that cut more cleanly. Do not forget to check the fuel tank size. A small tank means more refills. Finally, do not buy a mower without checking the availability of spare parts. Brands like Mountfield and Draper have good parts support.
