Frequently asked questions
- Is a petrol mower better than a cordless one?
- Petrol mowers offer more power and unlimited runtime for large lawns, but need fuel, oil and maintenance. Cordless models are quieter and cleaner for smaller gardens.
- What is a self-propelled mower?
- A self-propelled mower drives its own wheels, so you guide rather than push it. This reduces effort on larger lawns, slopes or when collecting heavy, wet grass.
- What maintenance does a petrol mower need?
- Regular tasks include changing the oil, cleaning or replacing the air filter and spark plug, keeping the blade sharp, and using fresh fuel each season for reliable starting.
