Mountfield 4065H
Best OverallPros
- Proven Briggs & Stratton engine
- Steel deck for durability
- 7 cutting height positions
Cons
- Heavier than alloy models
- No rear roller
The Mountfield 4065H uses a 125cc Briggs & Stratton engine, one of the most reliable small engines available. Owner reviews consistently praise its easy starting and consistent power delivery even on damp grass. The 46cm steel cutting deck handles medium-sized lawns efficiently without bogging down.
Height adjustment is simple with a single lever offering seven positions from 25mm to 75mm. The 50-litre grass collector is adequate for most gardens, though you may need to empty it more frequently on larger lawns. At 28kg, it is not the lightest, but the steel deck adds longevity that budget alloy models often lack.
Hyundai 140cc Petrol Lawn Mower
Best BudgetPros
- Lightweight alloy deck
- Powerful 140cc engine
- Large 60-litre collector
Cons
- Alloy deck less durable than steel
- Some reports of vibration
The Hyundai 140cc model offers the most power in this price bracket with its 140cc engine. The alloy deck keeps weight down to 24kg, making it easier to manoeuvre than the Mountfield. Owner reviews highlight its strong cutting performance on thick grass, though the alloy deck may dent more easily than steel alternatives.
The 60-litre grass collector is larger than most competitors, reducing trips to the compost heap. Height adjustment is manual with six positions, which is less convenient than the single-lever system on the Mountfield. For budget-conscious buyers needing raw power, this is a strong contender.
Bosch Rotak 43
Best Electric AlternativePros
- Extremely lightweight
- Excellent cut quality
- No fuel or maintenance
Cons
- Cord limits range
- Not for large lawns
The Bosch Rotak 43 is an electric corded mower that outperforms many petrol models in cut quality. At only 13kg, it is half the weight of petrol alternatives, making it ideal for smaller gardens where manoeuvrability matters. Owner reviews consistently rate its grass collection and cutting performance as excellent.
While not petrol, it deserves mention for those who value lightweight operation and lower running costs. The 43cm cutting width is slightly narrower than the petrol options, but the aluminium deck is durable and rust-resistant. For gardens under 300 square metres, this is often a better choice than a budget petrol mower.
Stihl RM 248 T
Best for Small GardensPros
- Stihl brand reliability
- Wide 48cm cut
- Easy height adjustment
Cons
- Can exceed £200 at times
- Smaller 40-litre collector
The Stihl RM 248 T offers the widest cutting width in this group at 48cm, helping you finish lawns faster. The 125cc Stihl engine is known for reliability and easy starting. Owner reviews note that it handles uneven ground well thanks to the sturdy steel deck and large wheels.
The 40-litre grass collector is smaller than competitors, which may require more frequent emptying on larger lawns. Height adjustment is centralised with a single lever, offering six positions. The Stihl brand commands a premium, so prices can fluctuate above £200, but it is often available within budget during sales.
Flymo Petrol 46
Best for Compact StoragePros
- Folding handles for storage
- Reliable Briggs engine
- Good value for money
Cons
- Plastic wheels feel less durable
- Average build quality
The Flymo Petrol 46 features folding handles that reduce storage space, a useful feature for those with limited shed room. It shares the same 125cc Briggs & Stratton engine as the Mountfield, providing reliable starting and consistent power. Owner reviews mention that it cuts well on regular lawns, though the plastic wheels may not last as long as rubber alternatives.
The 46cm steel deck is durable, and the 50-litre grass collector is standard for this class. Height adjustment is manual with six positions, which is functional but less convenient than centralised systems. For buyers prioritising compact storage, this is the best option under £200.
What to Check Before Buying a Petrol Lawn Mower Under £200
Engine displacement is the most important factor. Look for at least 125cc for reliable cutting on medium-sized lawns. Smaller engines may struggle with thick or damp grass.
Deck material matters for longevity. Steel decks are heavier but more durable than alloy. Alloy decks are lighter and resist rust but can dent more easily. For budget mowers, steel is often the better choice.
Cutting width affects how quickly you finish. A 46cm width is standard for this price range. Wider cuts save time but require more power, so ensure the engine matches the width.
Grass collector capacity varies from 40 to 60 litres. Larger collectors mean fewer trips to empty them, but they add weight. Consider your garden size when choosing.
Mistakes to Avoid
Do not ignore the weight. A 28kg mower is fine for flat lawns but can be exhausting on slopes or uneven ground. Check the weight before buying.
Avoid buying a mower with a tiny engine. Engines under 125cc often lack the torque needed for consistent cutting, especially in wet conditions. Stick with 125cc or higher.
Do not assume all petrol mowers are the same. Build quality varies significantly between brands. Stick with established names like Mountfield, Hyundai, or Stihl for better reliability.
FAQs
Are petrol lawn mowers better than electric?
Petrol mowers offer more power and no cord limitations, making them better for larger gardens. Electric mowers are lighter, quieter, and require less maintenance.
What size engine do I need for a medium lawn?
A 125cc to 140cc engine is ideal for medium lawns up to 500 square metres. Smaller engines may struggle with thick grass.
How often should I change the oil in a petrol mower?
Change the oil every 25 hours of use or at the start of each mowing season. Regular oil changes extend engine life significantly.
Can I use a petrol mower on wet grass?
It is possible, but not recommended. Wet grass clogs the deck and collector, and can cause uneven cutting. Wait for dry conditions.
What is the best brand for budget petrol mowers?
Mountfield and Hyundai offer the best reliability and value under £200. Stihl is also good but can be harder to find at this price.
How long do petrol mowers last?
With proper maintenance, a petrol mower can last 5 to 10 years. Steel deck models tend to last longer than alloy ones.
Do I need to winterise my petrol mower?
Yes, drain the fuel or add stabiliser before winter storage. This prevents carburettor issues and ensures easy starting in spring.
Is a 46cm cutting width enough for a large lawn?
For lawns over 500 square metres, a 46cm width is adequate but may take longer. Consider a 48cm or wider model for faster mowing.
What type of fuel should I use?
Use unleaded petrol with an octane rating of 95 or higher. Avoid ethanol-blended fuels if possible, as they can damage small engines.
Can I mulch with a budget petrol mower?
Most budget mowers do not include a mulching plug. Check the specifications or buy a separate mulching kit if needed.
Our verdict
The Mountfield 4065H is the best petrol lawn mower under £200, offering a reliable Briggs & Stratton engine, durable steel deck, and easy height adjustment. For budget buyers, the Hyundai 140cc provides more power at a lower price, though with a less durable alloy deck. Choose the Mountfield for long-term value and the Hyundai for immediate power needs.
