Key Factors to Consider
Choosing the best cordless lawn mower for large gardens requires careful consideration of several factors to ensure you get the right tool for your needs. Here are some key points to keep in mind:
-
Battery Life and Power: For large gardens, you’ll need a cordless lawn mower with a long-lasting battery. Look for models with high-capacity batteries, preferably lithium-ion, which offer longer run times and quicker charging. Also, consider the mower’s power output; a more powerful motor can handle tougher grass and provide a cleaner cut.
-
Cutting Width and Height Adjustability: A mower with a wider cutting width will cover more ground in less time, making it ideal for large gardens. However, ensure that the cutting width isn’t too wide for any narrow spaces you might have. Additionally, choose a mower that offers adjustable cutting heights. This feature allows you to tailor the grass length to your preference and the season’s growth.
-
Maneuverability and Weight: Since you’ll be using the mower over a larger area, ease of manoeuvrability is crucial. Opt for a lightweight design that’s easy to push or self-propelled models to reduce fatigue. Check the handle design too; ergonomic handles can make mowing more comfortable, especially for prolonged periods.
-
Durability and Build Quality: For large gardens, the mower will be in use for longer periods, so choosing one built to last is important. Look for models made from robust materials such as steel or heavy-duty plastic.
-
Noise Level: While cordless lawn mowers are generally quieter than petrol models, some still produce noticeable noise. If you prefer a quieter option for your garden, look for models specifically designed with noise reduction features.
How long does a cordless lawn mower battery last on a single charge?
The battery life of a cordless lawn mower varies depending on the model and the battery’s capacity. For large gardens, you’ll want a battery that lasts at least 50 minutes on a single charge. Some high-end models can provide up to 90 minutes of run time. It’s also worth considering mowers with interchangeable batteries, allowing you to continue mowing while the first battery charges. The run time will also depend on the mowing conditions, such as the length and thickness of the grass.
Can lawn mowers cut wet grass?
Yes, lawn mowers can cut wet grass, but it is generally not recommended. Cutting wet grass can be challenging for several reasons. Wet grass tends to clump together, which can clog the mower deck and affect performance. It can also be slippery, increasing the risk of slips or accidents.
Additionally, mowing wet grass can lead to an uneven cut, as the grass blades tend to bend under the weight of the water, preventing a clean, precise trim. For the best results, it’s advisable to wait until the grass is dry before mowing. If you must mow wet grass, consider raising the cutting height to prevent clogging and strain on the mower.
How do I maintain a cordless lawn mower to ensure it lasts?
Maintaining a cordless lawn mower involves a few simple steps. After each use, remove grass clippings from the mower deck to prevent build-up that can affect performance. Regularly check the blades for sharpness and replace or sharpen them as needed to ensure clean cuts. Store the mower in a dry place, especially the battery, to prevent damage from moisture.
Follow the manufacturer’s instructions regarding battery care, such as avoiding full discharges and keeping it charged during long periods of inactivity.
