FAQ

What engine sizes are typically found in mid-range petrol lawn mowers?

You’ll generally see engines ranging from 140cc to 200cc in this price range. Larger engines provide more power for tackling thicker grass and larger lawns, while smaller ones are lighter and easier to manoeuvre.

How much maintenance do these mowers require?

Petrol lawn mowers need regular upkeep – primarily oil changes every 25-50 hours of use, air filter cleaning, and blade sharpening. Following the manufacturer’s recommendations in your owner's manual will ensure optimal performance and longevity.

What kind of cutting widths should I consider?

Cutting widths typically range from around 38cm to 51cm. A wider cutting width covers more ground with each pass, reducing the total time spent mowing, but a narrower one is easier to manoeuvre in tight spaces.

Are there any specific features I should look for?

Look for features like adjustable height settings, easy-access air filters, and durable wheels. Some mowers also include options such as collection trays or mulching capabilities – consider what suits your mowing style.

What kind of fuel should I use?

Mid-range petrol lawn mowers typically require unleaded petrol with an octane rating of 91 or higher. Using the correct fuel ensures optimal engine performance and prevents damage.

How often should I sharpen my mower blades?

Sharpening your blades every 5-10 hours of use is crucial for maintaining a clean cut and preventing strain on the engine. Dull blades tear the grass, leading to an uneven finish and potentially damaging the lawn.

What safety precautions should I take when using a petrol mower?

Always wear appropriate personal protective equipment (PPE) such as eye protection and sturdy footwear. Never operate the mower near children or pets, and always follow the manufacturer’s safety instructions carefully.

How do I store my lawn mower over winter?

Store your mower in a dry, sheltered location to protect it from the elements. Drain the fuel tank completely before storing, and consider adding fuel stabilizer to prevent the fuel from degrading.

What is the typical lifespan of a mid-range petrol lawn mower?

With proper maintenance, you can expect a mid-range petrol lawn mower to last for 5-10 years. Regular servicing and careful use will significantly extend its lifespan.

Are there any differences in performance between different brands?

Performance varies depending on the brand and engine quality. Researching reviews and comparing specifications can help you choose a model that aligns with your specific lawn size and grass type requirements.
