Buying Guide: What to Look For in a 40V Lawn Mower
When I started looking for a new mower, I knew I wanted to ditch the gas can and the extension cord. That’s how I ended up in the world of 40V lawn mowers. They offer a fantastic sweet spot of power and runtime for most suburban lawns. But not all 40V mowers are created equal, and figuring out what matters can save you a lot of hassle later. Here’s what I learned you should focus on when choosing one of the 10 best 40V lawn mowers for cordless power.
First, think about battery life and whether you need a second battery. The amp-hour (Ah) rating on a battery tells you its capacity. A 2.0Ah battery will run out much faster than a 6.0Ah one. If your yard is a third of an acre or more, a larger battery or a model that comes with two batteries is a smart move. There’s nothing worse than running out of juice halfway through the job. Some mowers even have a port for a second battery, letting you hot-swap without stopping.
Next, consider the cutting deck. A wider deck means you’ll finish mowing faster because you cover more ground with each pass. For small, intricate yards, a 19-inch deck might be perfect for maneuvering. For larger, open spaces, look for a 21-inch or even 22-inch deck. The deck material matters, too. Steel is durable but can rust, while polymer is lightweight and resists corrosion.
Don’t ignore the cutting options. A single-lever height adjustment is a huge time-saver, letting you change the height on all wheels at once instead of fiddling with four separate levers. Also, check how the mower handles grass clippings. Do you want to bag for a clean look, mulch to feed your lawn, or discharge to the side? The best mowers offer all three options, so you can choose what works for your lawn on any given day.
Finally, pay attention to the little things that make a big difference in usability. How does it fold for storage? Is it easy to push? Does it have a battery charge indicator? These features might not seem like a big deal on the showroom floor, but they contribute massively to your overall experience. A mower that’s a pain to store or that leaves you guessing about battery life can quickly become a source of frustration.
FAQ
How long does a 40V lawn mower battery last on a single charge?
This is the number one question I had, and the answer depends on a few things. The main factors are the battery’s Amp-hour (Ah) rating and your lawn’s condition. A larger battery, like a 6.0Ah, will obviously last longer than a 2.0Ah. On average, with a standard 5.0Ah battery, you can expect about 45-60 minutes of runtime. But remember, thick, wet grass will drain the battery much faster than dry, thin grass. If you have a larger yard, looking at models with two batteries is a great strategy for ensuring you have enough power.
Can a 40V mower handle tall or thick grass?
Yes, but with a major caveat. Modern 40V mowers have plenty of power for most tasks, but they aren’t invincible. If you let your grass get really out of control, you’ll need to take it slow. The best approach is to set the mower to its highest cutting setting for the first pass and then lower it for a second, cleaner cut. Trying to plow through foot-tall grass in one go will likely stall the mower and drain the battery extremely quickly. For regular maintenance mowing, they handle thick grass just fine.
Are 40V mowers as powerful as gas mowers?
This is a common comparison. While a high-end gas mower might still have a raw power advantage for the toughest conditions, for the vast majority of homeowners, a 40V mower is more than powerful enough. The technology has improved dramatically. You get instant start with the push of a button, much quieter operation, and zero emissions. You’re not giving up much practical power, and you’re gaining a ton of convenience and a cleaner environment. When you look at the list of the 10 best 40V lawn mowers for cordless power, you’ll find they are perfectly capable replacements for traditional gas mowers.
What is the main difference between 40V and 80V mowers?
Voltage generally relates to power, while Amp-hours (Ah) relate to runtime. An 80V mower will typically have more torque, which can be helpful for very hilly lawns or exceptionally thick grass. However, a 40V system is often more than sufficient for a typical flat or gently sloped quarter-to-half-acre lot. The 40V systems also tend to be lighter and sometimes more affordable. It’s a trade-off, but for most people, the 40V category offers the best balance of performance, weight, and cost.
How should I store my 40V mower battery during the winter?
Proper storage is key to making your battery last for years. I always remove the battery from the mower and store it indoors in a cool, dry place. Extreme heat or cold can damage the battery cells. It’s also a good idea to store it with a partial charge, around 40-80%, rather than fully charged or completely dead. Check the manufacturer’s instructions, as some brands have specific storage modes for their batteries.
