A gas-powered workhorse that laughs at thick grass and covers ground faster than any electric at this price.

If you have a quarter-acre or more, this is the mower that saves you the most time. The 21-inch steel deck cuts a noticeably wider path than the 16-inch models, and the 144cc 4-stroke OHV engine delivers reliable power without the cold-start fuss — buyers report it “starts right up” and cuts “long grass easily.” Unlike the cordless options that max out around 30 minutes, the PowerSmart keeps going as long as you have fuel, making it a true one-pass machine for larger lawns.

You get six cutting height positions from 1.5 inches to 3.9 inches, which covers everything from a tight summer trim to a taller spring cut. The 10-inch rear wheels and 7-inch front wheels (double ball-bearing) make pushing across uneven terrain smoother than the SENIX gas mower’s 7-inch wheels on all four corners. The 3-in-1 system — mulching, bagging, or side discharge — gives you flexibility that the bag-only cordless mowers can’t match. One reviewer noted the “foam grip arrived damaged” as a minor factory oversight, but the general consensus is that the build punches above its price.

At 61.6 pounds, it is notably heavier than every cordless option here, so you will feel it on steep slopes. But that weight also means a more stable cut on bumpy ground. If your yard demands raw power and you do not mind basic maintenance (oil changes, spark plugs), this gas mower is the most capable pick under.

A gas mower that matches the PowerSmart’s deck width and height range at an even lower price point.

The AMERISUN shares the same 21-inch cutting width and the same 144cc 4-stroke engine as the PowerSmart — and even the same 6-position height adjustment from 1.5 inches to 3.9 inches. That makes it a direct head-to-head competitor for anyone prioritizing coverage speed. Where it differentiates is the high-wheel design: the AMERISUN rides on 10-inch rear wheels and 7-inch front wheels, which gives it noticeably better glide over bumpy terrain and slopes compared to the SENIX gas mower’s uniform 7-inch wheels.

It also offers a 3-in-1 mowing system (mulch, side discharge, or rear bag), so you can choose how to handle clippings depending on the season. The heavy-duty steel deck feels built to last, and owners mention it “starts right up” and “cuts really well” even on neglected lawns. One reviewer raved that the self-propelled feature worked great and got the yard “done quickly,” though the engine itself is push-only — no power drive. The main downside reported is weight: at around 60 pounds (similar to the PowerSmart), it is a heavy machine for smaller or physically limited users. Another buyer mentioned a bent axle on arrival, which suggests packaging consistency could improve.

If you are comparing this against the cordless EWORK (which runs on 40V but has a 14-inch deck), the AMERISUN covers 21 inches per pass versus the EWORK’s 14 inches per pass and never runs out of battery mid-yard. It is not as quiet or as clean as an electric mower, but for raw cutting speed on a larger property, it is tough to beat at this price.

A nimble gas mower that handles hills and ditches better than heavier competition thanks to its lightweight body.

At 39.3 pounds, the SENIX is dramatically lighter than the PowerSmart (61.6 lbs) and AMERISUN gas mowers, making it the obvious choice if your yard has steep sections or awkward banks. The 20-inch cutting width still covers ground respectably — just an inch narrower than the 21-inch models — but the lighter frame means you can pivot and push uphill without feeling punished. Buyers confirm it is “perfect for ditches/slopes” and “pushes easily,” with a single-pull start that most owners found reliable.

The 144cc 4-cycle engine delivers the same 144cc displacement as the pricier gas mowers, but the SENIX only offers 3-position height adjustment (1.35 inches, 2.3 inches, and 3.15 inches). That is less flexibility than the 6-position PowerSmart or AMERISUN — you cannot make the fine seasonal tweaks those mowers allow. The 7-inch front and rear wheels are uniform, unlike the high-wheel design on the AMERISUN, so rough terrain feels bumpier. However, customers note it handles 6-8 inch wet grass “with a slower pace,” proving the engine has enough torque for overgrown conditions.

One assembly complaint stands out: the instructions lack labels for oil and gas fill points, which frustrated a novice buyer. But most owners found it “easy, 35-minute assembly” and praise the 2-year warranty. If slopes dominate your yard and you want gas power without the heaviness, this is your pick.

Infinite runtime and a 98% collection rate make this corded mower a surprising powerhouse for medium yards.

If you have a medium-sized lawn and do not mind dragging a cord, the DOVAMAN outperforms virtually every cordless option in its price class. The 13 Amp copper motor spins at 3500 RPM — higher than the MZK’s max of 3400 RPM — and delivers steady power without the runtime anxiety of battery mowers. The 13.2-gallon rear bag collects up to 98% of clippings under typical conditions, which means far less post-mow raking compared to the STEELITE’s bag or the EWORK’s 9-gallon catcher.

The 5-position single-lever height adjustment covers 0.98 inches to 2.95 inches, giving you a slightly wider low-end range than the MZK (which bottoms out at 1.3 inches). The 16-inch steel deck is a solid middle ground — wider than the MZK’s 13-inch deck by 3 inches, so you finish the job faster, but narrower than the 20-inch gas mowers if you have tight garden beds. Buyers rave about its performance, noting it is “lightweight, very easy to operate and eats weeds like hell” and that it “outperforms previous electric mowers.”

You do need a heavy-duty extension cord (100 feet recommended) and cord management around trees and obstacles can be tricky, as one reviewer pointed out. The blades also bend more easily on impact than a gas mower’s steel blade. But if you want the dependability of a plug that never dies and the cleanest collection on the list, this corded mower delivers.

A 17-inch cutting deck and dual batteries give this electric mower the widest battery-powered footprint on the list.

The STEELITE carves out a unique spot among the battery mowers by offering a 17-inch cutting width — noticeably wider than the MZK’s 13-inch and the EWORK’s 14-inch decks, which means you finish the lawn faster. It runs on two 20V 4.0Ah batteries wired for a 40V system, similar to the EWORK and Grelawner, and the brushless motor spins at 3400 RPM (matching the MZK’s high setting). The 6-step height adjustment ranges from 0.98 inches to 2.95 inches — the same low-end as the DOVAMAN corded mower but with more fine-tuning options.

Buyers consistently praise its lightweight feel — one reviewer called it “30 pounds if that” — and the 2-in-1 mulching and bagging design gives flexibility that the bag-only competition lacks. Another owner reported mowing “about twenty minutes in some fairly high thick grass before it shut down,” which aligns with the 25-minute advertised runtime. If you need more runtime for a bigger lawn, the reviewer suggested buying two extra batteries to rotate charges.

At 30 pounds, it is heavier than the Grelawner (25.13 lbs) and the MZK, but still easy to maneuver. The main complaint: battery life falls short of a full hour, and the “fast charge” is actually slow — some users report it taking all day to recharge both batteries fully. If your yard stays under a quarter-acre, the runtime is sufficient.

Lightest of the electric mowers at 25.13 lbs, with a 14.5-gallon bag that matches its runtime for fewer stops.

The Grelawner is the lightest battery mower on this list by a decent margin — at 25.13 pounds, it is noticeably easier to manage than the STEELITE (30 lbs) and far lighter than any gas mower. The 16-inch cutting deck is a useful upgrade over the 13-inch MZK and 14-inch EWORK, letting you cover 16 inches per pass compared to 13 inches on the MZK and 14 inches on the EWORK. The included 40V battery system powers a brushless motor that automatically adjusts output for thick or light grass, which is a smart feature you do not see on the cheaper MZK or EWORK models.

The 14.5-gallon collection bag is the largest among the cordless mowers here — the MZK holds 8 gallons and the EWORK holds 9 gallons — so you make fewer trips to the compost pile. The 5-position height adjustment (1.18 inches to 2.95 inches) covers a similar range to the STEELITE but with one fewer setting. Shoppers say the mower “mows great” and handles normal grass well, though one buyer mentioned the battery “does not last very long” and needs two charges to finish their lawn.

The headline drawback: replacement batteries are hard to find, so losing battery capacity over time is a genuine concern. The auto-choke system on the gas models is not relevant here, but the push-button start is genuinely instant and quiet. If you want the lightest possible electric mower with the biggest collection bag, the Grelawner is the one.

A lightweight 40V mower with a 3800 RPM motor that spins faster than any other electric on the list.

The EWORK stands out because its 3800 RPM copper motor spins faster than the MZK (3400 RPM max) and the STEELITE (3400 RPM), giving it an edge in cutting through dense grass despite its compact 14-inch deck. The 40V system (two 20V 4.0Ah batteries) powers the motor, and the 6-position height adjustment goes from 0.86 inches to 2.44 inches — the lowest minimum height on any electric mower here, beating the MZK’s 1.3-inch floor. That means you can scalp the lawn lower in early spring if you want a tighter trim.

The 9-gallon grass bag is smaller than the Grelawner’s 14.5-gallon bag but large enough for a small yard. Buyers confirm “two batteries last a full cut” for a 540 sq ft yard, and the mower handles “overgrown yard well” with the batteries lasting a full hour. At 29 pounds, it is heavier than the Grelawner (25.13 lbs) but lighter than the STEELITE (30 lbs) and DOVAMAN (28.9 lbs). The foldable handle makes storage easy, and the double safety switch adds confidence.

Comparing the height ranges directly: the MZK adjusts from 1.3 inches to 2.6 inches, while the EWORK covers 0.86 inches to 2.44 inches — so the EWORK goes 0.44 inches lower but tops out 0.16 inches shorter. That lower range is helpful for Bermuda grass owners who want a very short cut. The main downside: at 14 inches, the cutting width is narrow — you will make more passes than with the 16-inch Grelawner or 17-inch STEELITE. Also, owners complain that replacement batteries are hard to find, so future-proofing is a concern.

The smallest deck on the list at 13 inches, but the lightest weight and the most universally praised battery runtime.

The MZK is the entry-level battery mower that just works — and buyers love it. Despite its 13-inch cutting width (narrower than every other electric mower here), it earns near-perfect reviews for being “lightweight, cordless, convenient for small-medium lawns” and for offering “easy maneuverability.” The brushless motor delivers 2800 RPM on Low and 3400 RPM on High, matching the STEELITE’s peak speed, and the 4-position height adjustment (1.3 inches to 2.6 inches) is simple to operate.

Where the MZK really shines is runtime. Buyers report the two 4.0Ah batteries last “2 full mows” on a small yard — that is better than the STEELITE (25 minutes rated) and the EWORK (about an hour). The 30-liter (8-gallon) rear bag is on the smaller side, but it is removable and easy to empty. The 2-step safety start prevents accidental startup, which is a nice touch for family use. At 13 inches, the deck is 4 inches narrower than the Grelawner and 4 inches narrower than the STEELITE, so you will take more passes for the same area — but the trade-off is a mower that feels featherlight and easy to push.

The downsides are clear: the 13-inch cut is the smallest on this list, and the 4-position height adjustment offers less fine-tuning than the 6-position EWORK or STEELITE. It is best suited for very small, flat lawns where you want a quick, quiet, no-hassle mow. The MZK does not offer mulching — it is bag-only — so if you want to leave clippings on the lawn, look at the STEELITE or Grelawner instead.

No gas, no battery, no noise — just a clean scissor cut that is healthier for your grass and the planet.

The LawnMaster reel mower is a completely different animal from everything else on this list. It uses a manual push motion to spin 5 steel blades against a bed knife, creating a scissor-like cut that severs grass cleanly instead of tearing it like a rotary blade. The 20-inch cutting width is actually the second widest on the list — only the 21-inch gas mowers beat it — and the 9-position height adjustment (1.3 inches to 2.6 inches) offers more fine-tuning than any other mower here.

Buyers confirm it works “well on short, level lawns” and requires “frequent mowing” — the exact conditions a reel mower needs. One reviewer captured the limit perfectly: “only cuts grass under 4 inches; taller grass is pushed over.” That means you cannot let the lawn get shaggy and then expect the reel mower to save you; it demands a consistent weekly schedule. The 10-inch front wheels help with navigation, and the assembly takes about 5 minutes. The cut quality, when used correctly, is genuinely superior to a gas mower — the blades do not shred the grass tips, which means less browning and a healthier lawn.

Compared to the MZK (13-inch deck, 4 positions) or the EWORK (14-inch deck, 6 positions), the LawnMaster offers wider coverage and more height options. But it is physically harder work — you provide all the power. It is also less forgiving of rocks, sticks, and uneven terrain, as one owner reported: “jams easily on mulch, stems, or uneven terrain.” If you have a small, flat, well-maintained lawn and want zero emissions and zero fuel costs, the LawnMaster is the most honest pick on the list.
