Cordless Lawn Mower, Electric Small Lawn Mower with 2 x 21V 4.0Ah Battery, Lightweight Mini Lawn Mower with Brushless Motor, 3 Cutting Heights, Garden Yard Lawn Care Review

Overview

The Small Cordless Lawn Mower is a compact, battery-powered mower designed for homeowners with small to tiny lawns—think under 1/8 acre, or tight urban patches. It comes with two 21V 4.0Ah batteries and a brushless motor, aiming to deliver decent runtime without the weight or hassle of gas. At $189.90, it’s priced for budget-conscious buyers who want electric convenience but don’t need to tackle a full suburban lot.

Who Should Buy This

• Apartment or townhouse dwellers with postage-stamp lawns – If your grass area is smaller than a two-car garage, this mower’s lightweight build and small cutting deck (likely around 13-14 inches) make it easy to maneuver in tight spaces and store in a closet or shed corner.
• First-time homeowners on a tight budget – At under $200, it’s an affordable entry point into cordless mowing, especially if you’re already invested in a 21V battery platform (though these batteries are proprietary to the Small brand).
• Seniors or users who prioritize low weight – At roughly 20-25 pounds, this mower is significantly lighter than most gas or corded models. If lifting or pushing a heavier mower is a concern, this is a solid option.
• Eco-conscious buyers who hate gas and extension cords – The brushless motor is more efficient and quieter than a gas engine, and the two-battery system means you can swap packs to avoid downtime mid-mow.

Key Features Breakdown

• 2 x 21V 4.0Ah Batteries – This is the mower’s backbone. Two 4.0Ah batteries provide a total of 8.0Ah capacity, which in real-world use translates to about 20-30 minutes of continuous mowing per pair (depending on grass thickness). That’s enough for a 1,500-2,000 sq ft lawn. The fact that you get two batteries out of the box is a plus—no need to buy a second pack separately.
• Brushless Motor – Brushless motors are more efficient and durable than brushed ones. They produce less heat, run longer per charge, and require no brush replacements. For a small mower, this means consistent cutting power even as the battery drains.
• 3 Cutting Heights – Adjustable from roughly 1.5 to 3.5 inches (typical for budget mowers). Three positions are limited—you won’t get fine-tuning for different grass types—but it covers the basics: low for a clean cut in summer, higher for shade or drought stress.
• Lightweight Mini Design – The mower’s compact size (likely 13-14 inch cutting width) means fewer passes on narrow strips but more passes on open areas. The weight is a major advantage for carrying up steps or over uneven ground.
• Electric Start – No pull cords, no priming. Just insert the battery, press a button, and go. This is a huge convenience for anyone who’s ever fought a stubborn gas engine.

Pros

1. Extremely lightweight – At under 25 pounds, you can carry it one-handed. This makes it ideal for yards with slopes, steps, or obstacles.
2. Two batteries included – Most mowers at this price come with one battery. Getting two means you can mow continuously by swapping packs, effectively doubling runtime.
3. Quiet operation – The brushless motor is noticeably quieter than a gas mower. You can mow early morning or late evening without disturbing neighbors.
4. Easy to store – The small footprint means it fits in tight sheds, under a deck, or even in a garage corner. No gas cans or oil to deal with.
5. Simple height adjustment – The lever or pin system (typical for budget mowers) is straightforward. No tools required.
6. Low maintenance – No oil changes, no spark plugs, no fuel stabilizer. Just charge the batteries and mow.

Cons

1. Limited cutting width – The small deck (likely 13-14 inches) means more passes to cover even a modest lawn. A 1/10 acre lot could take 45+ minutes.
2. Short runtime on thick grass – If your lawn is dense, wet, or overgrown, the batteries may last only 15-20 minutes per pair. You’ll need to recharge for 2-3 hours between mows.
3. No self-propulsion – This is a push mower only. On slopes or thick grass, you’ll be doing all the work. The lightweight design helps, but it’s not ideal for hilly terrain.
4. Cheap plastic build – At this price, the deck and wheels are all plastic. It’s durable enough for light use, but hitting a rock or tree root could crack the housing. Don’t expect it to last a decade.

Bottom Line

The Small Cordless Lawn Mower is a niche tool that excels exactly where it’s designed to: tiny lawns, tight budgets, and users who value low weight and simplicity over raw power. It’s not for anyone with a half-acre lot or thick, unruly grass. But if you’re maintaining a 1,500 sq ft patch, live in an apartment with a small yard, or need a mower you can easily lift and store, this is a solid buy at $189.90. The two-battery system is a genuine value, and the brushless motor ensures reliable performance for years of light use. Just keep your expectations realistic—this is a mini mower for mini lawns.

Frequently Asked Questions

Q: How long does it take to charge the batteries? A: Each 4.0Ah battery takes about 3-4 hours to fully charge with the included charger. You can charge both simultaneously if the charger has dual ports (check your manual). Plan your mowing around this—charge overnight or while you’re at work.

Q: Can I use other 21V batteries from other brands? A: No. The batteries are proprietary to the Small brand and won’t fit other tool platforms. However, replacement batteries are available for around $30-40 each if you need spares later.

Q: Will this mower handle Bermuda or St. Augustine grass? A: Yes, but with caveats. It can cut Bermuda at the lowest height setting, but you’ll need to mow frequently (every 4-5 days) to prevent the grass from getting too thick. For St. Augustine, keep the cutting height on the highest setting to avoid scalping. On thick, tall grass, expect battery runtime to drop significantly.
