FAQ
What kind of lawns are these mowers best suited for?+
These 31L capacity lawn mowers excel on medium to large lawns, typically up to 75 square metres. They’re ideal for regular maintenance and provide a consistent cut across various grass types, including standard mixtures and some coarser varieties.
How often should I empty the 31L grass box?+
Emptying the grass box after each mowing session is recommended to maintain optimal cutting performance. A full box can impede airflow and reduce the effectiveness of the blades, leading to uneven cuts.
What type of fuel do these mowers use?+
Most models in this range utilize petrol (typically unleaded), however, specific models may vary – always check the product details for exact fuel requirements before purchase.
How do I adjust the cutting height?+
Adjusting the cutting height is usually done via a lever or dial located on the handle. This allows you to select your desired grass length and ensures a consistent cut across your lawn.
Are these mowers easy to start?+
Many models feature electric start, significantly reducing the effort required to start the engine. Manual starting options are also available on certain models – check the product specifications.
What safety features do these mowers have?+
Key safety features include a blade brake system which stops the blades immediately when the handle is released, and often incorporate high-mounted cutting decks to reduce the risk of pedestrian incidents.
How much maintenance do these lawn mowers require?+
Regular maintenance, including oil changes and spark plug checks, is crucial for optimal performance. Follow the manufacturer’s recommended schedule outlined in the user manual for best results.
What should I do after each mowing session?+
After each use, clean the underside of the mower with a damp cloth to remove grass clippings and debris. This prevents build-up and ensures efficient operation.
Are these mowers suitable for uneven terrain?+
While generally capable, these mowers may struggle on extremely uneven or steeply sloping ground. Consider a ride-on lawnmower if your property has significant variations in elevation.
Can I store these mowers over the winter?+
