You’ll appreciate the ultra-lightweight frame, ergonomic handles, and push-button start that make chores feel communal, not solitary.

Blade material is durable steel for consistent cuts. Warranty and 40V tool compatibility reinforce value, so you’ll feel confident joining other smart, eco-conscious owners. This mower is ideal for homeowners who enjoy maintaining their outdoor spaces and want a reliable, easy-to-use tool for their yard self-propelled mowers.
How Long the Battery Lasts and Real‑World Runtime Performance
You’ll get a clear sense of real-world battery life after that full kit runs through a few lawns: the included 4.0Ah 40V battery typically delivers about 35–45 minutes of mowing per charge, which usually covers small yards and many medium lawns up to roughly half an acre if you mow efficiently. In runtime testing I found consistent times on flat, trimmed turf; heavy grass or hills shortens that. You’ll want to plan for gradual battery degradation over years, and you can swap batteries between tools to stay productive. Overall, runtime fits most homeowners who value convenience and tool compatibility. The mower is part of a broader range of battery-powered mowers designed for homeowners who enjoy their outdoor space.
Cut Quality, Height Adjustment, and 2‑in‑1 Mulching vs. Bagging
Although the 16″ deck is compact, it delivers a clean, even cut on regular turf, and the Smart Cut Adjustment System lets you dial blade height precisely from 1.25″ to 3.375″ with a single lever. You’ll notice consistent stripe-free results when blades stay sharp—blade sharpness matters for tear-free edges and healthier grass. The 2-in-1 design switches quickly between mulching and rear-bagging, so you can choose fine clippings for soil feed or collect for a tidy finish. Mulching shows minimal clumping behavior when grass is dry and trimmed regularly. Overall, it’s predictable and community-minded lawn care you can count on. The mower pair well with essential push mower accessories and maintenance items to keep performance reliable over time.
Noise, Weight, Handling, and Ease of Use During Mowing
After appreciating the cut quality and quick switch between mulching and bagging, you’ll notice the Greenworks mower stays quietly in the background while you work. Its quiet operation (under 75 dB) means you can mow without shouting or disturbing neighbors. At roughly 35% lighter than rivals, you’ll lift and store it with less strain. The ergonomic balance and comfortable handles make turns and long passes feel natural, reducing fatigue. Push-button start and simple height adjustments keep things effortless. Overall, you’ll find mowing quicker and more pleasant—accessible for new owners yet dependable for seasoned weekend warriors. This makes it a strong choice for homeowners who value cordless mowers and easy yard care.

Some Questions Answered
Can I Expand Runtime With a Larger-Capacity Battery?
Yes — you can get longer runtime with a battery upgrade. If you swap the included 4.0Ah for a higher‑capacity Greenworks 40V battery, you’ll extend mowing time and cover more yard in one charge. You’ll want a compatible pack from their 40V line to avoid issues. Upgrading feels empowering, saves recharge stops, and helps you belong to the tool ecosystem while keeping performance consistent and maintenance simple.
Is the Mower Compatible With Third-Party Batteries?
No — you shouldn’t rely on third-party batteries. For safe battery compatibility you’ll want Greenworks-approved packs that meet the 40V voltage limits and connector standards; third-party cells can mismatch voltage, fail safety circuits, or void warranties. If you want longer runtime, stick with larger-capacity Greenworks batteries or a matched OEM higher‑Ah pack. That keeps performance consistent, preserves your warranty, and helps you feel confident and included in the Greenworks ecosystem.
How Do Replacement Blades and Parts Cost and Where to Buy Them?
Replacement pricing for blades and parts is generally modest: expect blades around $15–30 and small parts $5–50. You’ll find parts sources at Greenworks’ official site, authorized dealers, and major retailers (Amazon, Home Depot, Lowe’s). You’ll also locate compatible third-party blades—compare specs and reviews. You’ll save time by buying kits or bundled hardware, and you’ll feel supported using authorized channels that honor the warranty and offer reliable returns.
Can It Be Stored Outdoors or Left Attached to the Battery?
No, you shouldn’t store it outdoors or leave the battery attached. You’ll want to remove the battery for safe battery storage and keep both mower and battery in a dry, temperature-controlled spot to avoid outdoor exposure damage and reduced battery life. Store battery partially charged per the manual, away from direct sun and freezing temps. Doing this protects performance, extends life, and helps you feel confident your gear’s ready when you need it.
Is the Mower Safe for Slopes and Steep Driveways?
Yes — you can use it on gentle slopes, but you should follow tilt precautions and avoid steep inclines. You’ll get decent traction control from its lightweight design, yet it won’t match a heavy gas mower on very steep driveways. Stay with a downhill walking pattern, keep both feet stable, and don’t let the battery run low mid-slope. If you’re unsure, invite a friend to help for safety and confidence.
