Flymo vs Stihl Petrol Lawn Mower
Choosing between a Flymo and a Stihl petrol lawn mower often comes down to garden size versus build longevity. Flymo offers lighter, more affordable models for smaller lawns, while Stihl delivers professional-grade durability and cutting performance for larger, more demanding terrain.
Quick answer
For most medium-to-large gardens, the Stihl petrol mower range is the better investment due to superior engine reliability, heavier-duty steel decks, and longer service life. Flymo petrol mowers are a solid budget-friendly choice for smaller, flat lawns where weight and price are the main concerns.

Flymo vs Stihl: Which Petrol Mower Brand is Right for You?
Flymo and Stihl are two well-known names in lawn care, but they serve different segments of the market. Flymo is a UK-based brand that focuses on lightweight, affordable mowers often aimed at smaller gardens. Stihl, a German manufacturer, is renowned for its professional-grade outdoor power equipment, including chainsaws, trimmers, and lawn mowers that are built to last for years of heavy use.
When comparing petrol mowers from these two brands, the differences in build philosophy become clear. Flymo petrol mowers typically use plastic or lighter steel decks and are easier to manoeuvre, making them a good fit for flat lawns under 500 square metres. Stihl petrol mowers, on the other hand, feature heavy-gauge steel decks, more powerful engines, and larger collection bags, making them suitable for larger, rougher terrain.
Owner reviews from major retailers consistently highlight Stihl's superior reliability and cutting quality, while Flymo owners often praise the lighter weight and lower price point. Both brands have their place, but the right choice depends heavily on your garden size, terrain, and how long you expect the mower to last.
What to Check Before Buying a Petrol Lawn Mower
Before deciding between Flymo and Stihl, consider these key factors that affect real-world performance and ownership costs.
- Engine type and power: Stihl uses its own 4-Mix engine which combines two-stroke power with four-stroke emissions. Flymo uses Briggs & Stratton or Honda engines, which are reliable but can be harder to service.
- Deck material: Steel decks last longer but add weight. Plastic decks are lighter but can crack over time on uneven ground.
- Cutting width: Wider decks cut faster but are heavier and harder to turn. For lawns over 500 sq m, a 46 cm or wider deck is recommended.
- Self-propulsion: Essential for sloping or large lawns. Flymo offers it on some models; Stihl includes it as standard on most petrol mowers.
- Grass collection: Larger bags (60 litres or more) mean fewer trips to the compost heap. Stihl generally offers bigger collection boxes.
- Warranty and parts availability: Stihl has a wider dealer network and longer warranty periods, which can reduce long-term costs.
Mistakes to Avoid When Choosing a Petrol Mower
- Buying too heavy a mower for a small garden: A 40 kg Stihl mower can be a pain to manoeuvre on a tiny lawn. Measure your garden area first.
- Ignoring terrain: Flymo's lighter build suits flat lawns. Stihl's heavier chassis handles slopes better without bouncing.
- Overlooking storage: Stihl mowers are larger and bulkier. Make sure your shed or garage can accommodate the dimensions.
- Choosing based on price alone: A cheaper Flymo may need replacing sooner, especially if used on rough ground or left outside.
- Forgetting about servicing: Stihl dealers are widespread, but Flymo service centres can be harder to find in rural areas.
Flymo Petrol Mowers: Key Features and Limitations
Flymo petrol mowers are designed with the domestic user in mind. They are generally lighter, easier to start, and more affordable than Stihl equivalents. Many models feature a plastic deck that resists rust and keeps the weight down to around 25-30 kg, which is manageable for most users. Flymo also offers a range of cutting widths from 40 cm to 46 cm, which suits smaller to medium lawns.
However, the lighter construction comes with trade-offs. Owner reviews on major UK retail sites note that Flymo petrol mowers can feel less robust over time, particularly the plastic decks which may crack if struck against a rock or kerb. The engines, while reliable, are not as fuel-efficient or low-emission as Stihl's 4-Mix units. Parts availability can also be an issue for older models, and the warranty period is typically shorter at two years.
Flymo's strength lies in its value proposition. For a gardener with a flat, well-maintained lawn of under 400 square metres, a Flymo petrol mower offers a good balance of performance and cost. The lighter weight also makes it a better choice for users who need to carry the mower up steps or lift it into a high shed.
Stihl Petrol Mowers: Build Quality and Long-Term Value
Stihl's petrol mowers are built to a higher standard, both in terms of materials and engineering. The decks are made from heavy-gauge steel that can withstand years of use on rough terrain without warping or cracking. The Stihl 4-Mix engine is a standout feature, offering the power of a two-stroke with the fuel efficiency and low emissions of a four-stroke. This means less smoke, lower fuel costs, and a quieter running experience.
Stihl mowers also come with larger grass collection bags (often 60-80 litres), which means fewer stops during mowing. The self-propulsion system on Stihl models is generally more robust and adjustable, allowing users to match the speed to their walking pace. The warranty period is longer too, typically three to five years depending on the model and retailer.
The main downside is weight and price. Stihl petrol mowers are heavier, often weighing 35-45 kg, which can make them harder to push on flat ground without self-propulsion. The initial purchase price is also higher, often 30-50% more than a comparable Flymo model. However, many owners report that the higher upfront cost is offset by a longer service life and better resale value.
Performance Comparison: Cutting Quality and Grass Collection
Both brands offer decent cutting quality, but Stihl generally has the edge in consistency. The heavier steel deck on Stihl mowers provides better suction, which lifts grass for a cleaner cut, especially in damp conditions. Flymo's lighter decks can struggle with wet grass, leading to clumping or an uneven finish.
Grass collection is another area where Stihl excels. The larger bags and better airflow mean less clogging and fewer stops. Flymo's collection bags are adequate for dry, short grass but can fill up quickly or block when the grass is long or damp. Owner reviews on Amazon and other sites frequently mention this difference, with Stihl owners reporting less time spent emptying the bag.
Build Quality and Longevity: Which Lasts Longer?
Stihl is the clear winner in terms of build quality and longevity. The heavy-gauge steel decks, sealed bearings, and robust engine components are designed for commercial-level use. Many Stihl owners report mowers lasting 10-15 years with proper maintenance. Flymo petrol mowers, while adequate for lighter use, typically have a shorter lifespan of 5-8 years before components like the plastic deck or engine mounts start to show wear.
Parts availability also favours Stihl. The brand has a vast dealer network across the UK and US, and spare parts are generally easy to source. Flymo parts can be harder to find, especially for older models, and may require ordering online rather than picking up from a local shop.
Price and Value: What You Get for Your Money
Flymo petrol mowers are more affordable upfront, with prices typically ranging from £200 to £400 depending on the model and features. Stihl petrol mowers start at around £400 and can go up to £800 or more for larger, self-propelled models. The higher price reflects the better materials, longer warranty, and superior engine technology.
When considering value over time, Stihl often works out cheaper per year of use. A £300 Flymo that lasts 6 years costs £50 per year. A £600 Stihl that lasts 12 years costs the same £50 per year, but with better performance and fewer repairs. For users who plan to keep the mower for a decade or more, Stihl represents better long-term value.
Which Brand is Best for Different Garden Types?
For small, flat lawns under 300 square metres, a Flymo petrol mower is often sufficient and more budget-friendly. The lighter weight makes it easier to store and manoeuvre. For medium gardens between 300 and 800 square metres, Stihl's self-propelled models offer better cutting performance and collection capacity. For large gardens over 800 square metres or those with slopes and rough ground, Stihl is the only sensible choice due to its robust build and powerful engine.
Users with mobility issues may prefer Flymo's lighter weight, while those who want a mower that can handle thick, wet grass without clogging should lean towards Stihl. The choice also depends on how much you value long-term reliability versus initial cost savings.
