The Mountfield HP41 petrol lawnmower features a 123cc ST120 Autochoke petrol engine, providing reliable power for small to medium-sized gardens up to 250m². With its 39cm cutting width, it’s appropriate for covering moderate lawn areas efficiently. The hand-propelled nature of the mower means you’ll need to push it, which can be good for maneuverability but may require more effort compared to self-propelled models.

The mower includes a 40L grass collector, which is quite convenient for gathering clippings without frequent emptying. Adjustable cutting heights ranging from 25mm to 70mm in five positions allow versatility depending on your grass length preference. The lightweight chassis (19 kg) with grooved wheels enhances its maneuverability across different terrains, making it user-friendly.

The rust-proof polypropylene body adds durability, while the foldable handles make for easy storage and transportation. However, the 0.75L fuel tank might need frequent refilling for larger tasks. If you’re looking for a straightforward and efficient mower for a medium-sized garden, this model offers solid performance.

Buying Guide for the Best Petrol Lawn Mowers

Choosing the right petrol lawn mower can make maintaining your lawn a much easier and more efficient task. When selecting a petrol lawn mower, it's important to consider the size and type of your lawn, as well as your own physical capabilities and preferences. Petrol lawn mowers are known for their power and ability to handle larger lawns with ease, but they also require more maintenance than electric models. Understanding the key specifications will help you make an informed decision that best suits your needs.
Engine PowerEngine power in petrol lawn mowers is measured in horsepower (HP) or cubic centimeters (cc). This spec is important because it determines how effectively the mower can cut through thick or tall grass. Generally, more power means better performance, especially for larger lawns or tougher grass. For small to medium-sized lawns, an engine with around 125cc to 150cc should suffice. For larger lawns or more challenging terrain, consider a mower with 160cc or more. Choose based on the size of your lawn and the type of grass you have.
Cutting WidthThe cutting width refers to the width of the strip of grass that the mower can cut in a single pass. This is important because it affects how quickly you can mow your lawn. A wider cutting width means fewer passes are needed, which can save time on larger lawns. For small lawns, a cutting width of 30-40 cm is usually adequate. Medium lawns might benefit from 40-50 cm, while large lawns may require 50 cm or more. Consider the size of your lawn and how much time you want to spend mowing.
Cutting Height AdjustmentCutting height adjustment allows you to change the height at which the grass is cut. This is important for maintaining the health of your lawn, as different grass types and seasons may require different cutting heights. Most mowers offer several height settings, typically ranging from 20mm to 70mm. If you want flexibility in lawn care, look for a mower with a wide range of height adjustments. Choose based on the type of grass you have and the desired appearance of your lawn.
Self-Propelled vs. PushSelf-propelled mowers have a drive system that moves the mower forward, reducing the effort needed to push it. This is important for larger lawns or if you have physical limitations. Push mowers require more effort but can be more maneuverable and are often lighter. If you have a large or hilly lawn, a self-propelled mower can make the task much easier. For smaller, flat lawns, a push mower might be sufficient and offer more control.
Grass Collection OptionsGrass collection options refer to how the mower deals with the clippings. Common options include bagging, mulching, and side discharge. This is important for lawn maintenance and cleanliness. Bagging collects clippings for disposal, mulching finely chops them to return nutrients to the lawn, and side discharge expels them to the side. If you prefer a tidy lawn, bagging might be best. For a more eco-friendly approach, consider mulching. Choose based on your lawn care preferences.
Fuel Tank CapacityFuel tank capacity determines how long the mower can run before needing a refill. This is important for uninterrupted mowing sessions, especially on larger lawns. A larger tank means fewer stops to refuel, which can be convenient. For small lawns, a smaller tank may be sufficient, while larger lawns might benefit from a larger capacity to avoid frequent refueling. Consider the size of your lawn and how often you want to stop for refueling.
