FAQ

What size lawn mower should I buy for a small garden?+

For gardens under 50m², a lightweight petrol or electric rotary mower is usually sufficient. Rotary mowers offer better cutting performance on uneven lawns, while smaller electric models are quieter and easier to maintain – consider a 32cc petrol or equivalent wattage electric motor.

What materials are lawn mowers typically made from?+

Most small garden lawn mowers use steel for the deck and chassis, providing durability. Some have plastic components for lighter weight and cost-effectiveness, but ensure any plastic is UV resistant to withstand sun exposure.

How much do small lawn mowers generally cost?+

You can find basic electric rotary mowers starting from around £150, while more powerful petrol models range from £250 to £500. Higher-end electric self-propel models with features like variable speed can exceed £600.

How much maintenance do lawn mowers require?+

Petrol mowers need regular oil and air filter changes (every 25-50 hours of use) and spark plug checks. Electric mowers require minimal maintenance, typically just cleaning the blades after each use and checking the battery charge.

Are there any safety regulations I should be aware of?+

All lawn mowers must comply with European Machinery Directive 2006/42/EC, including safety features like a blade guard and audible warning signal. Always wear appropriate PPE – safety glasses and sturdy footwear – when operating.

When is the best time to mow my lawn?+

Avoid mowing during extreme heat or very wet conditions which can damage the grass. Generally, aim to mow in the cooler parts of the day, like early morning or late afternoon, to reduce stress on your lawn.

What’s the difference between a rotary and cylinder mower?+

Rotary mowers use a spinning disc with blades to cut the grass, suitable for uneven lawns. Cylinder mowers use a fixed blade that ‘slices’ through the grass, producing a cleaner finish but struggling on taller or longer grass.

How often should I sharpen my lawn mower blades?+

Sharpen your blades whenever you notice them pulling or bogging down – typically every 6-12 mowing sessions for petrol mowers and more frequently if using an electric model with long grass.

Can I use a cordless electric lawn mower?+

Yes, cordless electric mowers are increasingly popular due to their convenience and reduced emissions. However, battery life can be limited by weather conditions (cold temperatures reduce performance) and the size of your garden.

Are there any legal restrictions on using petrol lawn mowers?+

Check local council regulations regarding noise levels – many have permitted hours for operation, typically between 8am and 8pm. Also, be mindful of pedestrian access when mowing near roads or pavements.
