Cutting Height Adjustment
The adjustable cutting height is effective, with users noticing a significant 'difference in cut height' between settings.
Self-Propelled vs. Push
The Mountfield SP41 is praised for being 'easy to start and self-propelled,' offering convenience right from the first use.
Weight and Maneuverability
This mower is described as 'lightweight,' making it manageable and easy to maneuver, especially in tight spaces.

The Mountfield SP41 Petrol Lawnmower stands out with its self-propelled operation, making it easier to manage especially in medium-sized gardens up to 250m². With a 123cc ST120 Autochoke engine, it provides reliable power, complemented by a 39cm cutting width, which is suitable for small to medium gardens. The mower's lightweight design, at just 21kg, paired with its polypropylene rust-proof chassis, enhances maneuverability and durability, making it a practical choice for those who need to navigate tight garden spaces.

A notable feature is the adjustable cutting height, offering five positions between 22mm and 80mm. This flexibility allows for a tailored cut depending on your lawn's needs. The 40L grass collector is a convenient addition, easing the disposal process. However, the fuel tank capacity of 0.75L, while adequate for smaller gardens, might require more frequent refueling for larger areas or more extended use.

The self-propelled feature provides ease of use, particularly on flat terrain, although it might not be as effective on steeper inclines. Also, while the polypropylene material is lightweight, it may not be as robust as steel in the long run. For those seeking a balance between performance and ease of use in a petrol mower, especially in smaller to medium gardens, the Mountfield SP41 offers a thoughtful blend of features. Its user-friendly design and manageable weight make it accessible for most users, though those with larger or more challenging terrains might need to consider mowers with larger cutting widths and more durable builds.

The mower's build quality is impressive, feeling sturdy and well-constructed, and it looks fantastic.

The Hyundai 20"/51cm 196cc Electric-start Self-propelled Petrol Lawnmower is a robust choice for medium to large lawns, thanks to its powerful 196cc 4-stroke petrol engine that promises easy starting and low fuel consumption. Its 20-inch cutting width ensures efficient mowing, while the six adjustable cutting heights allow you to achieve the perfect lawn finish. Being self-propelled, it offers great convenience with selectable walking speeds, making it easier to maneuver without the need for pushing.

The electric start feature adds convenience, although it also has a recoil backup. The large 70-liter grass collector bag reduces the frequency of emptying, and the mulching option is a bonus for those who prefer to recycle grass clippings. Foldable handles make it compact and easy to store, and the inclusion of cup/can holders is a thoughtful detail for user comfort. Weighing 43.8 kilograms, it's relatively heavy which might affect maneuverability for some users.

Durability is assured with its alloy steel build, and the peace of mind from a 3-year home-use warranty further adds to its appeal. However, the heavier weight and larger size could be a downside if you have limited storage space or smaller lawn areas. This lawnmower is an excellent choice for those needing a powerful and feature-rich mower for larger lawns, with durability and convenience at the forefront.

The Mountfield HP41 Petrol Lawnmower is a hand-propelled, fuel-powered mower with a 39cm cutting width that makes it suitable for small to medium-sized gardens, covering up to 250m². It features a 123cc ST120 Autochoke petrol engine, which ensures reliable starting and efficient operation. The 40L grass collector is a convenient addition for managing grass clippings, and its lightweight design (19kg) coupled with a rust-proof polypropylene chassis enhances maneuverability and durability.

The adjustable cutting height with five positions (25-70mm) provides flexibility in maintaining different lawn conditions. However, since it is hand-propelled, it may require more effort compared to self-propelled models, especially on uneven terrains. The 0.75L fuel tank may need frequent refilling for larger lawns. The mower's light weight and foldable handles facilitate easy storage and transportation.

Its performance and ease of use are commendable, but it may not be ideal for very large gardens or for users who prefer a self-propelled model. Nonetheless, it remains a strong choice for those with small to medium-sized lawns seeking a reliable and user-friendly petrol mower.

Buying Guide for the Best Petrol Mowers

Choosing the right petrol mower can make a significant difference in maintaining your lawn efficiently and effectively. Petrol mowers are known for their power and ability to handle larger lawns with ease. When selecting a petrol mower, it's important to consider various specifications to ensure it meets your specific needs. Here are some key specs to look out for and how to navigate them.
Engine PowerEngine power, measured in horsepower (HP) or cubic centimeters (cc), determines the mower's ability to cut through thick and tall grass. Higher engine power means more cutting strength and efficiency. For small to medium lawns, an engine with 125-150cc is usually sufficient. For larger lawns or tougher grass, consider engines with 190cc or more. Choose based on the size of your lawn and the type of grass you have.
Cutting WidthCutting width refers to the width of the mower's cutting deck and determines how much grass is cut in a single pass. Wider cutting widths (20-22 inches) are ideal for larger lawns as they reduce mowing time. Narrower cutting widths (16-18 inches) are better for smaller lawns or areas with tight spaces. Select a cutting width that matches the size of your lawn and the amount of maneuverability you need.
Cutting Height AdjustmentCutting height adjustment allows you to change the height at which the mower cuts the grass. This is important for maintaining the health of your lawn, as different grass types and seasons require different cutting heights. Look for mowers with multiple height settings (usually 1-4 inches) to give you flexibility. Choose a mower that offers easy and precise height adjustments to suit your lawn care routine.
Self-Propelled vs. PushSelf-propelled mowers have a drive system that moves the mower forward, reducing the effort needed to push it. This is especially useful for larger lawns or hilly terrain. Push mowers, on the other hand, require manual effort to move and are better suited for smaller, flat lawns. Decide based on the size and topography of your lawn and your physical ability to push the mower.
Grass Clipping ManagementGrass clipping management refers to how the mower handles the grass clippings. Options include bagging, mulching, and side discharge. Bagging collects clippings in a bag for easy disposal, mulching finely chops clippings and returns them to the lawn as fertilizer, and side discharge ejects clippings to the side. Choose a mower with the clipping management option that best fits your lawn care preferences.
Fuel Tank CapacityFuel tank capacity determines how long the mower can run before needing a refill. Larger tanks mean longer mowing sessions without interruption, which is beneficial for larger lawns. Smaller tanks are lighter and may be sufficient for smaller lawns. Consider the size of your lawn and how often you want to refuel when choosing the fuel tank capacity.
Weight and ManeuverabilityThe weight of the mower affects how easy it is to maneuver, especially around obstacles and on slopes. Lighter mowers are easier to handle but may have less power. Heavier mowers are more stable and powerful but can be harder to push. Balance the weight with the power and consider your physical ability to handle the mower when making your choice.
Durability and Build QualityDurability and build quality determine how long the mower will last and how well it can withstand regular use. Look for mowers with sturdy construction, preferably with metal decks and high-quality components. A durable mower will save you money in the long run by reducing the need for repairs and replacements. Choose a mower that is built to last, especially if you plan to use it frequently.
