What is a Self-Propelled Lawn Mower & Why Choose One?
For those with medium to large gardens, or those finding traditional push mowers a bit of a strain, a self-propelled lawn mower can be a real game-changer. Unlike a push mower, a self-propelled model uses a motor to drive the wheels, reducing the physical effort required to cut your lawn. This is particularly beneficial for larger gardens, those with slopes, or for individuals with limited mobility.
There are three primary drive types:
- Front-Wheel Drive: Generally more affordable and easier to manoeuvre on flat surfaces.
- Rear-Wheel Drive: Provides superior traction, making them ideal for slopes and uneven terrain.
- All-Wheel Drive: Offers the best traction and control, but is usually the most expensive option.
Types of Self-Propelled Lawn Mowers Available in the UK
Petrol Self-Propelled Lawn Mowers
Petrol mowers offer powerful performance and are suitable for large gardens where a power cable would be impractical. They typically have higher cutting speeds and can handle thicker, longer grass. However, they require more maintenance (oil changes, air filter cleaning) and produce emissions.
- Pros: Powerful, suitable for large gardens, no cable restrictions.
- Cons: Noisy, require maintenance, produce emissions, can be harder to start.
Electric (Corded & Cordless) Self-Propelled Lawn Mowers
Electric mowers are becoming increasingly popular, offering a quieter and more environmentally friendly alternative to petrol. Corded models provide consistent power but limit your range. Cordless models offer freedom of movement but rely on battery life.
- Pros (Corded): Quiet, low maintenance, environmentally friendly, consistent power.
- Cons (Corded): Limited range, cable can be cumbersome.
- Pros (Cordless): Quiet, low maintenance, environmentally friendly, freedom of movement.
- Cons (Cordless): Limited battery life, can be expensive.
Robotic Self-Propelled Lawnmowers
Robotic lawnmowers offer the ultimate convenience, automatically mowing your lawn on a pre-programmed schedule. They require initial setup (boundary wire installation) and are best suited for relatively flat, well-maintained lawns.
- Pros: Fully automated, quiet, consistent cut.
- Cons: Expensive, requires initial setup, not ideal for complex gardens or very long grass.
Key Features to Consider When Buying a Self-Propelled Mower
Cutting Width
Determines how much grass you cut with each pass. Wider cutting widths are faster for large lawns, but can be harder to manoeuvre in tight spaces.
Engine/Motor Power
For petrol mowers, measured in cc (cubic centimetres). Higher cc generally means more power. For electric mowers, measured in Volts (V). Higher voltage translates to greater power and longer run times.
Drive System
As discussed earlier, consider front-wheel, rear-wheel, or all-wheel drive based on your garden terrain.
Blade Height Adjustment
Allows you to adjust the cutting height to suit different grass types and conditions. Look for mowers with multiple height settings.
Grass Collection Capacity
A larger grass collection box means fewer trips to empty it.
Safety Features
Features like deadman’s levers, blade brake systems, and safety switches are essential for safe operation.
Mulching Capability
Mulching mowers chop grass clippings into fine pieces and return them to the lawn as fertiliser.
Foldable Handles
Makes storage easier, especially in smaller sheds or garages.

FAQs: Self-Propelled Lawn Mowers
Q: What is the difference between front-wheel and rear-wheel drive?
Front-wheel drive is generally more manoeuvrable and affordable, suitable for flat lawns. Rear-wheel drive offers better traction on slopes and uneven terrain.
Q: How long do cordless lawn mower batteries last?
Battery life varies depending on the voltage, amp-hour rating, and usage. Expect 30-60 minutes of runtime on a fully charged battery, but this can be extended with multiple batteries.
Q: Are robotic lawn mowers difficult to set up?
Initial setup requires laying a boundary wire around your lawn, which can be time-consuming. However, once set up, they are very easy to operate.
Q: How often should I sharpen my lawn mower blades?
Ideally, sharpen your blades at least once a year, or more frequently if you mow a lot of tough grass or encounter obstacles.
Q: Can a self-propelled mower be used on very uneven ground?
While self-propelled mowers are better suited to uneven ground than push mowers, extremely bumpy terrain may still be challenging. A rear-wheel or all-wheel drive model is recommended for moderately uneven ground.
