GreenWorks Pro 80-volt System offers a range of commercial-grade tools for professionals and everyday homeowner who simply want more power from an eco-friendly tool. This 21-inch cordless lawn mower has a durable steel deck, large 10-inch rear wheels, and Smart Cut load sensing technology . It’s lightweight, easy to use, and has a single-lever height adjustment and 3-in-1 operation for mulching, bagging, and discharging. Designed with durability and heavy- duty jobs in mind, the Pro GLM801600 features a brushless motor that delivers the power and performance of a 160cc gas engine. And with an extra battery on hand, you can tear through your grass without the hassle and emissions of gas. Compatible batteries currently include a 2ah (model GBA80200) and 4ah (model GBA80400) battery and rapid charger (model GCH8040). The 2ah battery charges within 30 minutes, so you can get back to work and finish your job asap. The 4ah battery charges within one hour…not too shabby.

Ease of Use

There’s a chance that once you start using battery-operated lawn mowers with electric motors, you might say goodbye to messier, oil-based mowers. The GLM801600 is blissfully cordless and one of the more ergonomic models from Greenworks. Regarding height adjustment, it’s simple with the Pro GLM8011600 thanks to its seven variable cutting heights that range from 1.25 inches to 3.75 inches. You can easily adjust the height of the cutting blades while moving, and you don’t need to fumble around with multiple levers like on some lawn mowers. This easy-to-use machine has a single lever that operators can easily adjust based on the cutting height required–and you don’t have to turn off the machine while setting the height.

There’s not much to say regarding assembling parts because it only takes about 30 minutes. As many in the country are getting ready to mow this spring, they may notice a thick layer of winter weed wreaking havoc on their lawns. But thanks to this mower’s intuitive Smart-Cut Technology, any sprawling lawn (up to one-fourth of an acre) will be beautifully manicured in less than an hour. Sure, you may need to take a few passes over really frosted areas, but that’s not a huge hassle all things considered. If you want, wait to use this mower until it’s sunny and the wet patches are minimal. Weighing in at a slim 55 pounds, this mower can be used by many and doesn’t tire you out. What’s more, the handle is cushioned for comfort, and you can adjust it to three different heights, meaning hand cramps aren’t an issue.

Cut Quality & Options

Overall, the cut quality of the Pro GLM801600 Pro, with its 21-inches steel deck, is solid thanks to the revolutionary Smart-Cut Technology. And yet, if your lawn has major overgrowth, you know, tall grass that’s higher than 4 inches, you may run the risk of the cut grass getting entangled with the blades. What’s pretty cool, though, is that the machine will beep to signify for you to stop and untangle the mess.

If you’re sick of using bulky, oil-based, heavy-duty mowers because of their headache-inducing noise and emissions, then it pays to purchase this mower, even if it means you’ll struggle at times with taller grass. What you could do to rectify the situation is prune your lawn once a week to cut down on yard overgrowth and a possible messy lawn-cutting situation. This versatile machine also mulches, which is great for your lawn, or you can use the bagging or side discharge options.

The warranty coverage for household use of this power tool from GreenWorks is an impressive four years. That includes materials, parts, and workmanship. Since you’ll need to buy the battery separately, the coverage for that and the charger is limited to one year. Mowers could potentially face the issue of getting the blades entwined with a large chunk of grass and the mower not functioning at the same speed, even after removing the debris. Luckily, GreenWorks has a toll-free helpline for warranty service to assist with problems like that. Just dial the number and have professionals come over to replace the blade in the next few days. If all goes well, however, you won’t experience that many maintenance issues, especially since this machine is quite durable.

Typical maintenance on this mower includes replacing the cutting blade when needed, cleaning the mower, safely disposing of the batteries when they become unusable, and storing the mower properly.

Safety Features

The Pro mower has a safety lock-out button required for starting and a ball lever to stop the mower at once. A grass catcher bag, a side discharge chute, and rear chute cover also provide operator safety from debris.

Special Features

To some folks, the GreenWorks Pro might resemble a race car thanks to its angled design and large wheels. It may look a tad bulky, but once you hit the yard you’ll see that it’s simple to maneuver. The mower is made from a tough polymer that can take a beating while producing zero emissions, and it does this without tying operator’s down with an annoying electrical cord.

The wide cutting deck allows you to mow your lawn efficiently by cutting down on the number of passes required to mow it. There is also a height-adjustment lever that lets you choose from seven cutting heights, allowing you to give your lawn a smooth, polished, and even look.

Along with its long battery life, the Pro features GreenWorks’ automatic power-adjusting system, which monitors the power needed to cut your lawn and adjusts the battery accordingly to extend the mower’s run time. The engine also directs extra power to the dual blades to make quick work of thick grass.

Cost Effectiveness

The bad news is that this mower comes without a battery and charger. The good news is that once you purchase both, they’ll work with the Greenworks battery and charger models GBA80200, GBA80400 and GCH8040. So if you plan to buy a trimmer, chainsaw, or hedger when the weather starts to get warmer, you’ll definitely save money by using the same battery on several Greenworks Pro tools.

Additionally, as mentioned above, this mower does not require the usual parts, fuel, and maintenance of a gas-powered machine, saving you money in the long run.
