Greenworks 40V 16" Brushless Cordless (Push) Lawn Mower (75+ Compatible Tools), 4.0Ah Battery and Charger Included Review

Overview

The Greenworks 40V 16" Brushless Cordless Push Mower is a compact, lightweight electric mower designed for small to medium lawns (up to 1/4 acre) and homeowners who want to ditch gas, oil, and pull cords without sacrificing cutting performance. It’s ideal for tidy, manageable yards where maneuverability and low maintenance matter more than raw power—think urban lots, tight side yards, or anyone tired of wrestling a heavy gas mower around flower beds.

Who Should Buy This

1. Suburban homeowners with 1/4 acre or less – This mower’s 4.0Ah battery handles a typical 6,000–8,000 sq ft lawn on a single charge, making it a perfect fit for smaller suburban lots without the hassle of extension cords.

2. First-time lawn care buyers or renters – If you’re new to lawn care or living in a rental with a small yard, this mower’s low price, simple operation (push-button start, no gas or oil), and included battery and charger make it an easy, low-commitment entry point.

3. Homeowners who hate gas cans and carburetors – Anyone tired of winterizing engines, dealing with stale gas, or cleaning spark plugs will love the zero-maintenance electric experience. Plug in the battery, press a button, and mow.

4. Those with narrow gates or tight storage – At just 16 inches wide and roughly 30 pounds, this mower slips through standard garden gates and stows easily in a shed corner or garage shelf—no wrestling a 50-pound behemoth.

Key Features Breakdown

• 40V Brushless Motor – Brushless motors are more efficient and last longer than brushed motors. This means more torque per charge, quieter operation, and no brushes to replace. It’s a meaningful upgrade over older electric mowers, especially for cutting thicker grass.

• 16-Inch Cutting Deck – This is a narrow deck by modern standards. The trade-off: you’ll make more passes on a larger lawn, but you gain exceptional maneuverability around flower beds, trees, and tight corners. Best for yards under 1/4 acre.

• 4.0Ah Battery & Charger Included – The 4.0Ah battery is a solid mid-capacity pack. On a typical lawn 6,000–8,000 sq ft, you’ll get a full mow on one charge. If your lawn is closer to 10,000 sq ft or very thick, you may need a second battery (sold separately). The charger refills in about 1.5–2 hours.

• Single Lever 7-Position Height Adjustment – A single lever controls all four wheels simultaneously, with heights from 1.5 to 4 inches. This is a time-saver over adjusting each wheel individually, and the range covers everything from a tight 1.5-inch cut to a tall 4-inch setting for hot weather or Bermuda grass.

• 75+ Compatible Tools – Greenworks’ 40V platform includes trimmers, blowers, chainsaws, and more. If you already own Greenworks 40V tools, this mower shares the same battery—a huge perk for reducing clutter and cost.

• Push Mower (No Self-Propulsion) – This is a manual push model. On flat, small lawns that’s fine, but on hills or for anyone with mobility concerns, the lack of self-propulsion can be a workout.

Pros

1. Incredibly quiet operation – At around 75 decibels, you can mow early Saturday morning without waking the neighbors or needing ear protection (though I still recommend it for comfort).

2. Lightweight and easy to push – At 30 pounds (battery included), it’s one of the lightest cordless mowers on the market. Great for seniors, smaller-framed users, or anyone who dreads pushing a heavy mower.

3. No gas, oil, or spark plugs – Zero maintenance beyond blade sharpening and cleaning the deck. Store it for winter with no prep—just pull the battery.

4. Instant start with no pull cord – Press one button and go. No priming, no choking, no yanking a cord 15 times. This is a game-changer for anyone who’s ever struggled with a stubborn gas engine.

5. Excellent maneuverability – The narrow 16-inch deck and light weight let you pivot around trees, navigate tight flower beds, and cut along fences with ease. It feels more like a precision tool than a brute-force machine.

6. Battery compatibility across Greenworks 40V tools – If you already own a Greenworks 40V trimmer or blower, you’re set. If not, you’re buying into a solid, expandable battery ecosystem.

Cons

1. Small cutting deck – 16 inches means more passes. On a 1/4-acre lawn, expect 30–40 minutes of mowing versus 20 minutes with a 21-inch mower. It’s a deliberate trade-off for maneuverability.

2. No self-propulsion – On flat ground, it’s fine. But if your lawn has any incline, you’ll feel the push. Not recommended for hilly properties.

3. Battery life is just adequate – The 4.0Ah battery will do a standard 1/4-acre lawn, but if your grass is thick or damp, you might run out before finishing. A second battery is almost a necessity for larger or tougher lawns.

4. Plastic deck feels less durable – The deck is high-impact plastic, which is light and rust-proof, but it doesn’t inspire the same confidence as a steel deck. Over time, it can crack if you hit a large rock or stump. That said, it’s common at this price point.

Bottom Line

The Greenworks 40V 16" Brushless Cordless Mower is a fantastic choice for small-lot homeowners, renters, or anyone tired of gas mower headaches—provided you’re realistic about its limitations. The narrow deck and lack of self-propulsion make it a poor fit for large or hilly lawns, but for a tidy 1/4-acre or less, it delivers quiet, instant-start convenience at a price that’s hard to beat. If you value maneuverability and low maintenance over raw speed, this is a solid buy. I’d recommend it confidently for anyone with a flat, small yard who wants to leave gas cans in the past.

Frequently Asked Questions

Q: Can this mower handle thick or wet grass?
A: It handles moderately thick grass well thanks to the brushless motor, but wet grass can bog it down quickly. For best results, mow when the grass is dry and don’t let it get too tall (cut no more than 1/3 of the blade height at a time). If you have very thick St. Augustine or Bermuda, consider a mower with a wider deck and more torque
