8 Best Electric Lawn Mowers for Long Grass 2025

The EGO POWER+ LM2101 isn’t just another electric mower—it’s a game-changer for long, unruly grass. With a 56V brushless motor and 45-minute runtime on the included 5.0Ah battery, this mower slices through thick overgrowth like butter, delivering clean, consistent cuts even in the most challenging conditions. Its 4-inch maximum cutting height and 6-position single-lever deck adjustment make it ideal for tackling tall, matted grass without bogging down—exactly what sets it apart from lesser models. Say goodbye to multiple passes and uneven patches; this machine was built for dominance over neglected lawns.

In real-world testing, the LM2101 handled dense, 6-inch-high grass with ease, maintaining blade speed and power thanks to its high-torque motor. The 1.5 to 4-inch height range gives flexibility for everything from a crisp summer trim to a deep spring cleanup. The 21-inch cutting deck covers ground quickly, reducing mowing time by nearly 30% compared to 18-inch models. While the foldable handle saves storage space, the mower’s 60-pound weight makes it less ideal for steep slopes or tight corners. It excels on flat to moderate terrain but demands a bit more effort on uneven ground.

When stacked against the Greenworks 60V or YARDCARE 36V, the EGO stands tall—not just in power, but in overall polish and performance consistency. It’s the premium choice for homeowners with larger yards and persistent long-grass challenges, offering reliability that cheaper cordless models simply can’t match. While it lacks a smart display or dual batteries, its battery ecosystem and rapid charging ensure minimal downtime. Compared to the Greenworks 60V, it delivers superior power and cut quality at a higher investment, but for those serious about lawn care, the payoff is undeniable.

If you’re battling thick, fibrous grass and want long-term reliability, the Greenworks 60V 17-inch mower is a silent powerhouse you can’t ignore. Its brushless motor delivers consistent torque even under load, allowing it to chew through damp, overgrown turf without stalling—a common flaw in budget mowers. With 40 minutes of runtime and a 60V platform, it’s part of a robust 75+ tool ecosystem, making it a smart long-term investment for serious DIYers. The 1.5 to 3.15-inch height range may fall short for extreme overgrowth, but for regular maintenance of long grass, it’s impressively capable.

During testing, this mower showed excellent blade responsiveness on wet, tangled grass, thanks to the brushless motor’s efficiency. The 17-inch deck is nimble in tight spaces, though it requires more passes on larger lawns. It handles slight inclines and uneven terrain well, and the rear bag fills evenly without clogging. However, in extremely tall grass (over 5 inches), it occasionally struggles to maintain speed, requiring a second pass. The 80-minute recharge time is acceptable but not class-leading, and the lack of a runtime extension option limits marathon mowing sessions.

Compared to the EGO LM2101, the Greenworks trades cutting width and max height for lightweight agility and ecosystem value. It’s not the most powerful, but it’s one of the most future-proof—perfect for homeowners who want a scalable cordless system. For those already using Greenworks tools, this mower integrates seamlessly. It offers better long-term value than the YARDCARE 36V despite a narrower deck, thanks to its higher voltage and motor efficiency.

For those dealing with consistently thick, coarse grass, the American Lawn Mower 51319 is a no-nonsense workhorse that refuses to quit. Its 13-amp motor delivers uninterrupted power—no battery fade, no recharging—making it a beast in long-grass scenarios where cordless models tap out. The 19-inch cutting deck and 1 to 3-inch height range strike a smart balance between coverage and precision, and the mulch plug and rear bag give real flexibility in lawn care strategy. It’s built for durability, not flash, and that’s exactly why it excels where others falter.

In real-world use, this mower powers through damp, tangled fescue and crabgrass without hesitation. The constant power supply means blade speed never dips, even in the thickest patches. It’s easy to maneuver around flower beds and trees, though the cord limits range and requires vigilance to avoid tripping or cutting. On flat lawns under half an acre, it’s incredibly efficient. However, on larger or irregularly shaped yards, managing the cord becomes a chore. The 3-inch max height is a limitation for spring cleanups, but for regular long-grass maintenance, it’s more than adequate.

Versus the LawnMaster MEB1216K, it offers similar power but a wider deck, giving it an edge in productivity. It’s not as portable as cordless options, but for budget-conscious users with smaller, accessible yards, it’s a reliable, low-maintenance solution. Compared to the EGO or Greenworks cordless models, it lacks convenience but wins on raw, sustained power and zero runtime anxiety. For tackling thick grass without breaking the bank, it’s a standout.

The MightyMow 2x20V is a surprise powerhouse in the budget cordless segment, packing dual 20V batteries and a brushless motor that spins at 4200 RPM—a rare combo at this price point. It’s built to conquer long grass with confidence, delivering 40 minutes of combined runtime and a 1.5 to 3-inch cutting range that handles most overgrowth with ease. The 18-inch deck and 40L grass bag make it efficient for small to medium yards, and the single-lever height adjustment ensures quick changes on the fly. It’s the definition of value-driven performance.

In testing, the mower maintained strong blade speed through moderately tall grass, though it began to strain in very wet, dense patches. The dual batteries are a major plus—swap one while mowing or combine for full power—but they’re 20V, not 40V+ like premium models, so raw torque lags behind the EGO or Greenworks 60V. The adjustable handle improves ergonomics, but the build feels slightly plasticky compared to higher-end models. On flat terrain, it’s a joy to use; on slopes, it can feel tippy due to weight distribution.

Against the YARDCARE 36V, the MightyMow offers better motor speed and dual batteries, but lacks a digital display or fine-tuned feedback. It’s not as refined, but for users who want maximum runtime and power per dollar, it’s hard to beat. It doesn’t match the cut quality of the EGO, but for budget-focused buyers needing real performance, it strikes a near-perfect balance.

The YARDCARE 36V isn’t the most powerful mower on the list, but it wins with smart design and user-centric features—especially its LED digital display, a rare gem in this price range. It shows real-time battery life, speed, and error alerts, eliminating guesswork during mowing. Powered by two 18V 4.0Ah batteries, it offers up to 60 minutes on low, making it ideal for small to medium lawns with long grass. The 3200 RPM brushless motor runs quietly and efficiently, though it lacks the punch for extremely thick or wet growth.

In real use, the mower performs well on dry, moderately tall grass, but slows in dense patches over 4 inches. The 5-position height adjustment (0.98″ to 2.56″) is limiting for serious overgrowth, but fine for regular maintenance. The 8-gallon bag is generous, and the 3-step safety start adds peace of mind for families. Charging takes about 2 hours, which is slow compared to competitors. While it’s light and easy to push, the smaller deck means more passes on larger lawns.

Compared to the MightyMow, it trades motor speed and dual-battery convenience for better usability and feedback. It’s not built for heavy-duty mowing, but for beginners or light-duty users, the display and safety features make it a standout. It offers more tech than the Greenworks 40V, though less power. For those who value information and ease of use over brute force, it’s a compelling pick.

The LawnMaster MEB1114K is the ultimate budget warrior, offering gas-like cutting power at a fraction of the cost. With a 14-inch deck and 3,300 RPM motor, it slices through long grass with surprising authority—no battery anxiety, no recharging. At just 28 lbs, it’s incredibly lightweight, making it a top pick for seniors or those with small, overgrown yards. The 7-gallon bag is compact but functional, and the 5 height settings allow decent customization. It’s not flashy, but it gets the job done reliably.

In testing, it handled dry, medium-height grass well, though it struggled in damp, matted patches due to the narrow deck and lower amp draw. The cord is a limitation, but for small, flat lawns, it’s manageable. The 7.75-inch wheels roll smoothly on even terrain but can dig in on soft soil. It’s not built for heavy-duty mowing, but for occasional use or light overgrowth, it’s impressively capable.

Against the LawnMaster MEB1216K, it loses in deck width and power, but wins in weight and affordability. It’s not as powerful as the American 51319, but it’s easier to store and maneuver. For first-time buyers or urban yards, it offers solid performance without the cordless price tag. It lacks the cutting width of the Greenworks 60V, but delivers better value for tiny lawns.

The Greenworks 40V 16-inch mower is the lightest contender here, and that’s its superpower. Weighing 35% less than average, it’s a dream for seniors, renters, or anyone with a small, patchy yard. Its 4.0Ah battery delivers 35 minutes of runtime, enough for lawns up to ½ acre, and the 5-position height adjustment (1.25″ to 3.375″) handles most long-grass scenarios. The 2-in-1 mulching and bagging system adds versatility, and the push-button start is instant and reliable. It’s quiet, clean, and effortless—perfect for low-impact lawn care.

In real use, it performs well on dry, medium-tall grass, but bogs down in wet or dense patches due to the small deck and lower torque. The 16-inch width means more passes, and the 3.375-inch max height is decent but not class-leading. Battery recharge takes 2 hours, which is slow. It’s not built for heavy mowing, but for weekly maintenance, it’s ideal. The ergonomic handle reduces fatigue, and the foldable design saves space.

Compared to the EGO or Greenworks 60V, it’s less powerful, but more portable and user-friendly. It’s not for large, overgrown lawns, but for small yards needing gentle, quiet mowing, it’s unmatched. It offers better ecosystem value than the YARDCARE, though less runtime. For light-duty users who prioritize comfort, it’s the best lightweight design.

The LawnMaster MEB1216K is a step up from basic corded mowers, combining 12 amps of power with a 16-inch deck for efficient cutting in long grass. It delivers 3,500 RPM—enough to handle moderate overgrowth without stalling—and the 8-gallon bag reduces emptying frequency. The 5 height settings and 8.86-inch rear wheels make it easy to maneuver, even on slightly uneven ground. At under 33 lbs, it’s light enough for most users and folds for storage.

In testing, it performed well on dry, tall grass, though it struggled in wet, matted areas. The cord limits range, but for small to medium yards, it’s manageable. It’s more powerful than the MEB1114K, with better wheels and a larger bag. However, like all corded models, it’s not ideal for large or complex lawns.

Versus the American 51319, it has less deck width and power, but is lighter and more maneuverable. It’s a solid mid-tier corded option—not the strongest, but reliable and affordable. For homeowners wanting a balance of power and ease, it’s a smart pick. It doesn’t match the runtime of cordless models, but offers better sustained power.
