Greenworks 40V 25" Brushless Cordless (Self-Propelled) Lawn Mower (75+ Compatible Tools), (2) 4.0Ah Batteries and Dual Port Rapid Charger Included Review

Overview

The Greenworks 40V 25" Brushless Cordless Self-Propelled Lawn Mower is a battery-powered machine designed for homeowners with medium-sized lawns—think a quarter to a third of an acre—who want to ditch gas, oil, and pull cords without sacrificing cutting performance. It pairs a 25-inch cutting deck (wider than the typical 20-21 inch electric mower) with a brushless motor and self-propulsion, all powered by two 4.0Ah batteries and a dual-port rapid charger. This is a solid workhorse for suburban yards where you need to cover ground efficiently but don’t want the hassle of gas maintenance or extension cords.

Who Should Buy This

• Homeowners with 1/4 to 1/3 acre lawns: The 25-inch deck and two 4.0Ah batteries give you enough runtime to handle these sizes in one go, especially if you don’t let the grass get too tall or thick. If your lawn is closer to a half acre, you might need a third battery or a faster pace.
• Gas-done buyers: If you’re tired of storing, mixing, and cleaning up after gas engines, this mower eliminates all of that. No more trips to the gas station, no more stale fuel, no more oil changes. Just charge and mow.
• Homeowners with gentle slopes: The self-propelled drive is rear-wheel, which works well on flat to mild hills. If you have steep terrain, you may want a front-wheel-drive or all-wheel-drive model, but for most suburban yards, this is perfect.
• Multi-tool Greenworks 40V users: This mower shares batteries with over 75 other Greenworks 40V tools—trimmers, blowers, chainsaws, etc. If you’re already in that ecosystem, this is a no-brainer upgrade.

Key Features Breakdown

• 40V Brushless Motor: Brushless motors are more efficient and durable than brushed ones. This means longer runtime per charge, less heat buildup, and more torque for cutting thicker grass. It’s the difference between a mower that struggles in wet grass and one that powers through.
• 25-Inch Cutting Deck: This is a big deal. Most battery mowers cap out at 21 inches. The extra 4 inches means fewer passes across your lawn, which translates to faster mowing and less battery drain. It’s a sweet spot for balancing maneuverability and coverage.
• Self-Propelled (Rear-Wheel Drive): Rear-wheel drive gives you better traction when the bagger is full or when going uphill, since the weight shifts to the back. The variable speed trigger lets you match your walking pace—slow for trimming near beds, fast for open stretches.
• Two 4.0Ah Batteries & Dual Port Rapid Charger: Greenworks includes two batteries, so you can swap mid-mow if needed (though one charge often handles a 1/4 acre). The dual-port charger charges both at once, cutting downtime significantly. A 4.0Ah battery is the sweet spot—enough capacity for real work without being overly heavy.
• 7-Position Single-Point Height Adjustment: A single lever adjusts all four wheels at once, from 1.5 to 4 inches. That’s easy to use and covers everything from a close cut for Bermuda grass to a taller cut for fescue in summer heat.
• 75+ Compatible Tools: This is a long-term value play. The same batteries work with trimmers, blowers, edgers, and even a chainsaw or hedge trimmer. If you build out your tool set, you’re never buying another battery platform.

Pros

1. Wide cutting deck for an electric mower: At 25 inches, this mower covers ground noticeably faster than the standard 20-21 inch electric models. You’ll finish your lawn in fewer laps.
2. Brushless motor delivers consistent power: Unlike some older brushed mowers that bog down in thick grass, the brushless motor cuts cleanly even when the grass is a bit damp or overgrown. It doesn’t lose speed under load.
3. Self-propulsion is smooth and responsive: The variable-speed trigger is intuitive—squeeze more for faster, less for slower. It’s not jerky or overly aggressive, which makes it easy to control around obstacles.
4. Two batteries included with rapid charger: Most competitors give you one battery and a slow charger. Greenworks includes two 4.0Ah packs and a charger that can fill both in under an hour. That’s real value.
5. Single-lever height adjustment: No bending over to adjust each wheel individually. One lever, seven positions, done. It’s a small thing that saves time every mow.
6. Ecosystem compatibility: If you already own Greenworks 40V tools, you’re set. If you don’t, this mower is a great entry point to a whole lineup of yard gear.

Cons

1. Battery run time is just adequate for 1/4 acre: With two 4.0Ah batteries, you’ll typically get 45-60 minutes of total runtime. For a 1/4 acre lawn, that’s usually enough. But if your grass is thick, wet, or tall, you may need to recharge one battery while using the other. A third battery is a smart investment for larger yards.
2. Self-propulsion can be finicky on steep hills: Rear-wheel drive is good for traction, but on very steep inclines (over 15-20 degrees), the drive wheels can slip, especially if the grass is wet. This isn’t a hill-climber—it’s a suburban slope mower.
3. Plastic deck feels a bit light duty: The deck is durable composite, but it’s not steel. Over time, hitting rocks or roots can cause cracks or stress marks. It’s fine for typical use, but if you have a rocky yard, consider a steel-deck model.
4. No mulching plug included: The mower comes with a bag and a side-discharge chute, but the mulching plug is sold separately. For a $480 mower, that’s an annoying omission. You’ll need to buy it ($15-20) if you want to mulch.

Bottom Line

The Greenworks 40V 25" Brushless Self-Propelled Mower is a strong choice for homeowners with medium-sized, relatively flat lawns who want to break free from gas and extension cords. The wide deck and brushless motor make it a fast, capable cutter, and the included two batteries and rapid charger are a genuine value-add. It’s not perfect—the plastic deck and missing mulching plug are real downsides, and the run time is tight for larger yards. But for its price point, it’s one of the best battery-powered mowers in this class. I’d recommend it confidently to anyone with a 1/4 to 1/3 acre lawn who’s ready to go cordless.
