Why I reached for this mower

I wanted a compact, battery-powered mower for small spaces that I could grab, cut, and put away without fuss. The MZK 13-inch cordless mower checked the right boxes on paper: dual 20V batteries (40V total), a brushless motor, a lightweight 24-pound chassis, and a modest 13-inch deck that would be easy to thread through narrow gates and around plantings. After several weeks of mowing small, suburban lawns and a few tight garden paths, I have a clear sense of where it excels and where it asks for compromise.

Setup and first impressions

Out of the box, setup was straightforward. Attaching the handle and fitting the grass bag took only a few minutes. The controls are simple: a safety interlock and a bail handle for the two-step start. Both batteries need to be seated for operation, which makes sense given the 40V system. The unit itself is compact and tidy, with a clean, rigid deck and a bag that clips on easily. There’s no pull cord to wrestle with, no fuel to store—exactly what I want for a quick midweek cut.

At 24.3 pounds, it’s genuinely easy to carry and lift. I could move it one-handed up short steps to a raised lawn. That light weight pays off during mowing too; it’s the kind of tool you can push with fingertips rather than leaning into it.

Cutting performance on small lawns

This mower is built for modest lawns and regular upkeep. In that scenario, it performs well. On a typical 1,600–2,000 square-foot cut, I was able to work steadily, keep a neat stripe, and leave a uniform finish without stalling. The brushless motor delivers consistent power for its size and helps keep noise and vibration low. It’s quiet enough that I didn’t feel self-conscious starting early in the morning.

Blade overlap is predictable, and the small deck actually helps around flower beds and tight edges. I could get closer to obstacles than with a 20-inch mower. If you’re mowing gated side yards, garden paths, or any space where a large deck is awkward, this size really shines.

If the grass gets away from you—say, past ankle height or very dense—you’ll need to slow down or take half-width passes. That’s typical for compact cordless mowers. It’s not a heavy-duty brush cutter. But for routine weekly trimming, it kept its pace and left a tidy cut.

Height adjustment: good mechanism, limited range

Adjustment is via a simple lever with four positions. The mechanism is positive and easy to operate, and it stays put. The limitation is the range itself. The listed range is low (around the low 1-inch mark up to the mid-1s), which is fine if you prefer a tight cut and mow frequently. For many grasses, especially in heat or during stress, I prefer a higher setting to protect the turf and reduce scalping. If you like mowing at 2.5–3 inches, you won’t find that here. In practice, I kept it on the highest setting and it still presented a short finish.

If you’re cutting cool-season turf in spring or maintaining a frequently clipped bermuda or zoysia, the lower range can look sharp. Just know that the mower favors a short lawn; it’s not ideal if you want a shaggy, drought-friendly height.

Battery life and charging

With two included 4Ah packs, I was able to finish a typical small-lawn session on one charge. Runtime varied with grass thickness and pace, but 30–45 minutes of continuous mowing is a fair expectation in average conditions. That’s enough for small yards; for anything larger, you can pause and swap, or simply plan to mow in sections.

Charging is painless. The included charger took the packs from low to full over a couple of hours, and I appreciated that I could top them up during a break and get back to work the same day. As with any battery tool, it’s worth charging both packs fully on day one and verifying they seat correctly in the tool.

Handling, balance, and ergonomics

Maneuverability is the standout. The mower glides with minimal effort and pivots easily around landscaping. The handle height felt natural; the controls were responsive; and the two-step start is quick once you get the rhythm. Because the unit is so light, it’s comfortable for users who might find a gas mower fatiguing. It also stores in tight spaces—compact enough to tuck along a garage wall or into a small shed without reorganizing everything else.

The bagger holds 25 liters. On a light clipping day, I emptied it once per small lawn. If the lawn is longer or you’re doing a first-of-season cut, expect to empty it more often. Bag attachment is simple, and the airflow is adequate for a mower this size. Without the bag, clippings disperse reasonably, though there’s no dedicated mulching mode listed and it doesn’t produce the ultra-fine clippings you’d get from a true mulcher.

Build quality and maintenance

The deck and housing feel solid for the weight class, and there’s nothing rattly or loose about the controls. The brushless motor is a plus from a maintenance perspective—no brushes to wear, and fewer moving parts overall than gas. Beyond keeping the blade sharp and knocking clippings out of the deck after use, there’s not much else to worry about. The safety start is well-implemented and reduces accidental activation when repositioning or emptying the bag.

As with all compact cordless mowers, avoid wet grass when you can. Wet clippings can clump and reduce bagging efficiency. If you do need to cut damp turf, slow your pace and keep an eye on the chute.

Where it fits best

• Small, flat yards and townhome lawns
• Frequent, light maintenance cuts
• Users who value low weight, low noise, and easy storage
• Tight spaces where a 13-inch deck is an advantage

Where it makes less sense:

• Larger lawns that benefit from a 19–21 inch deck
• Tall mowing heights (above roughly the mid-1-inch range)
• Infrequent cuts where grass gets long and dense

What I’d improve

• Height range: Four positions are fine, but a higher top setting would make the mower friendlier to more grass types and summer conditions.
• Deck size options: A companion 15–17 inch version would broaden appeal without losing the agility that makes this one nice to use.
• Clipping management: A mulching plug or improved fine-chop capability would reduce bagging for those who prefer lawn-cycling.

None of these are dealbreakers for the mower’s intended use, but they frame its best-fit scenario clearly.

The bottom line

The MZK 13-inch cordless mower is a thoughtfully balanced small-lawn machine. It’s quiet, genuinely lightweight, and easy to live with. The dual 20V system and brushless motor deliver steady, predictable performance for routine cuts, and the compact deck is excellent around obstacles and narrow spaces. The trade-offs are also clear: a narrow cutting path that extends mowing time on larger lawns, and a low height range that favors short, frequent cuts over taller turf.

Recommendation: I recommend this mower for small yards and regular maintenance where convenience, maneuverability, and low noise matter more than raw cutting width or tall cut heights. If your lawn fits that description and you want a simple, reliable battery mower that won’t wear you out—or take up much room in the shed—this one is a good fit. If you need higher mowing positions or you often tackle overgrown grass, consider a larger deck and a broader height range.
