Product Overview
The MZK 20V 13″ Electric Lawn Mower is a cordless, battery-powered push mower with a compact 13-inch cutting deck. It uses a brushless motor, which is generally a better sign of durability and efficiency than brushed alternatives in lower-cost cordless tools. It runs at 2800 RPM on Low and 3400 RPM on High, giving you two power settings depending on grass conditions.
The mower offers 4 cutting-height positions ranging from 1.3 inches to 2.6 inches, making it suitable for basic seasonal lawn maintenance. An 8-gallon removable rear grass bag keeps clippings contained and cleanup manageable.
One of its biggest selling points is that it ships as a complete kit: 1 mower, 2 x 20V 4.0Ah batteries, 1 single-port charger, and 1 grass bag. Many battery mowers are advertised at a low price but require additional battery purchases to be useful. Here, you get the essentials in the box.
The manufacturer claims up to 30 minutes of runtime on a full charge, though actual runtime depends on grass thickness, terrain, and power mode. For small yards, that’s typically enough. For larger properties, it may be limiting.
Pros & Cons
Pros
- Affordable complete kit: At $149 with two batteries and a charger included, it undercuts most cordless competitors that charge extra for batteries.
- Brushless motor: A meaningful upgrade at this price — brushless motors run more efficiently, generate less heat, and last longer than brushed designs.
- Two 4.0Ah batteries included: A backup battery reduces downtime, so you can finish mowing in one session. Many budget mowers only include one.
- Lightweight and maneuverable: The compact 13-inch deck is easy to push, turn, and store — ideal for narrow yards, tight corners, and small sheds.
- Simple height adjustment: Four cutting positions handle common seasonal mowing needs without fuss.
- Cleaner than gas: No fuel mixing, no oil changes, no pull cord. Charge it, mow, empty the bag, store it.
- Beginner-friendly safety: The 2-step safety start reduces accidental activation — a nice touch for households with kids or first-time users.
Cons
- Limited cutting width: A 13-inch deck means more passes on anything beyond a small lawn, adding time to medium-sized yards.
- Runtime constraints: 30 minutes is fine for small spaces but will require recharging breaks on larger properties.
- Basic cutting range: With a maximum height of 2.6 inches, it can’t handle taller grass preferences or overgrown lawns well.
- Small grass bag: The 8-gallon bag fills quickly and needs frequent emptying on thicker grass.
- Not for large properties: If you have more than a quarter acre, a wider-deck mower is a better fit.
Who Should Buy the MZK 20V 13″ Mower?
This mower is a great fit if you:
- Have a small yard, patio lawn, townhome greenspace, or garden strips
- Want to ditch gas, oil, and pull-cord maintenance entirely
- Need a lightweight mower that’s easy to carry and store
- Are buying your first mower and want a low-risk entry point
Look elsewhere if you have a medium-to-large property, need to cut grass taller than 2.6 inches, or want self-propelled drive and advanced features. In those cases, a 17″–21″ deck mower is the better investment.
Frequently Asked Questions
How long do the batteries last on a single charge?
The manufacturer claims up to 30 minutes of runtime across the two included 4.0Ah batteries. Real-world runtime varies with grass thickness, terrain, and power mode — expect closer to 20–25 minutes on thick or damp grass, and closer to the full 30 minutes on light, dry lawns.
Is the MZK 20V mower good for small yards?
Yes — that’s exactly what it’s designed for. The 13-inch deck and lightweight build make it ideal for lawns up to roughly a quarter acre, tight corners, and narrow side yards. Larger properties will require more passes and recharging breaks.
What cutting heights does it offer?
It offers 4 cutting-height positions ranging from 1.3 inches to 2.6 inches. That covers standard cool-season and warm-season lawn maintenance, though it can’t cut higher than 2.6 inches for those who prefer a longer lawn.
Does it come with batteries and a charger?
Yes. The kit includes 1 mower, 2 x 20V 4.0Ah batteries, 1 single-port charger, and 1 grass bag — everything you need to start mowing out of the box, with no extra purchases required.
Why does the brushless motor matter?
Brushless motors are more efficient than brushed motors because they eliminate friction-generating brushes. That translates to longer runtime per charge, less heat buildup, and a longer overall lifespan — a notable advantage at this budget price point, where most competitors still use brushed motors.
Is it hard to start or operate?
No. It uses a 2-step safety start — a deliberate design that prevents accidental activation, which is especially useful around kids or for first-time mower owners. Beyond that, operation is as simple as inserting a charged battery and pushing. No pull cords, priming, or fuel required.
Final Thoughts
The MZK 20V 13″ Cordless Brushless Lawn Mower, 2 Batteries delivers exactly what budget-minded small-yard owners need: a complete cordless kit with a modern brushless motor, dual batteries, and zero gas maintenance — all at $149. It won’t replace a wide-deck mower on a big property, but for small lawns, it’s one of the most complete and convenient packages in its price range. With a 4.5/5 rating from verified buyers, it earns our recommendation as a top budget pick.
