Pros & Cons

Pros

  • Powerful brushless motor exceeds the performance of gasoline engines
  • Versatile 3-in-1 functionality for mulching, bagging, or side discharge
  • User-friendly self-propelled system with variable speed fingertip control
  • Includes two high-capacity ARC Lithium batteries for maximum runtime

Cons

  • Premium price point reflects the advanced battery technology and bundle
  • Self-propel system usage can reduce the total runtime of the batteries
  • Large 21-inch deck may be bulky for very small or highly landscaped yards
Detailed Review

The EGO POWER+ LM2135SP represents a significant leap in battery-powered lawn care, specifically designed to replace gas mowers without sacrificing performance. At the heart of this machine is a brushless motor delivering 7.0 ft-lbs of torque, providing the muscle needed to tackle thick grass that often stalls lesser electric models. This specific bundle is a high-value package for those with larger residential lots, as it includes both a 7.5Ah and a 5.0Ah battery.

The standout feature is the Select Cut Multi-Blade System. Unlike standard mowers with a single blade, this unit uses an interchangeable lower blade system combined with a fixed upper blade to slice grass into fine fragments. Whether you are focused on pristine mulching or high-suction bagging, the specialized blades ensure professional-grade results. The Touch Drive self-propel system further enhances the experience, allowing you to engage the drive with palm pressure and adjust speed via a convenient dial.

Build quality is robust yet thoughtful. The mower features bright LED lights for those who prefer to work during cooler dawn or dusk hours. When the job is done, the handle folds down easily, allowing the unit to be stored upright to save floor space. While the initial cost is higher than some competitors, the inclusion of two premium batteries and a rapid charger provides a comprehensive ecosystem for the EGO 56V platform.

In terms of drawbacks, the self-propel feature is a power draw; users who rely heavily on maximum speed may see the 60-minute runtime decrease. Additionally, the sheer power and size mean it might be overkill for tiny urban patches. However, for the average homeowner looking to ditch the noise, fumes, and maintenance of gas, the LM2135SP is one of the most capable cordless options on the market.

Detailed Review

The Greenworks 80V 21 inch Self-Propelled Mower is a heavy-duty solution for homeowners looking to transition away from gas without sacrificing power. It utilizes a high-efficiency brushless motor that generates impressive torque, making it capable of handling overgrown grass and stubborn weeds that often stall weaker electric mowers. The inclusion of a 4.0Ah battery and rapid charger ensures you have the necessary fuel to maintain a medium-sized yard on a single charge.

Design-wise, this mower stands out with its rugged steel deck and rear-wheel drive system. The self-propelled feature is particularly beneficial for those with uneven terrain or slopes, as the variable speed control allows the user to set a comfortable pace. The 4-in-1 functionality provides maximum versatility, allowing you to switch between mulching, bagging, side discharge, or utilizing the turbo leaf pickup mode for fall cleanup.

One of the most significant advantages of this model is its integration into the Greenworks 80V ecosystem. If you already own or plan to buy other 80V tools like trimmers or blowers, the batteries are fully interchangeable, providing excellent long-term value. While the steel deck adds some weight compared to poly-deck competitors, the durability and improved cutting vacuum it provides are well worth the trade-off.

Overall, the Greenworks 80V Self-Propelled Mower is a top-tier choice for those seeking a professional-grade cut with the convenience of cordless technology. It is quiet enough for early morning work without disturbing neighbors and powerful enough to replace a gas mower permanently.

Pros

  • Impressive 50-minute runtime on a single charge
  • Quiet brushless motor with low vibration

Detailed Review

The EGO POWER+ LM2114SP represents a significant leap in battery-powered lawn care, offering 6.0 foot-pounds of cutting torque. This power level is designed to compete directly with gas-powered mowers, ensuring it can handle thick grass without the typical noise, maintenance, or exhaust fumes associated with internal combustion engines.

Built around a high-efficiency brushless motor, this mower is optimized for durability and runtime. The included 56V 6.0Ah ARC Lithium battery provides up to 50 minutes of continuous use, which is generally sufficient for most suburban yards. The self-propel system is particularly user-friendly, featuring dual-toggle levers that allow for comfortable operation with either hand and a speed dial for precise pace adjustments.

Versatility is a core strength of the LM2114SP. It offers a 3-in-1 functional design, allowing users to switch between mulching, bagging in the included two-bushel bag, or using the side discharge. The cutting height is easily managed via a single-handed lever, offering seven distinct positions ranging from 1.25 to 4 inches to suit different grass types and seasons.

While this model lacks the 'Select Cut' multi-blade system found in EGO's premium tier, it remains a robust performer for the average homeowner. The addition of bright LED headlights and the ability to fold the unit flat for vertical storage makes it a practical choice for those with limited garage space or those who prefer to mow during the cooler hours of early morning or twilight.

Ultimately, the EGO LM2114SP is a top-tier choice for eco-conscious homeowners who refuse to compromise on power. It delivers a clean, efficient cut with modern conveniences that make lawn maintenance less of a chore and more of a streamlined experience.

Pros

  • Powerful brushless motor with quiet operation
  • Self-propelled drive makes mowing easy on slopes and uneven ground
  • Comes with both mower and trimmer for a complete lawn care package
  • Battery runtime up to 45 minutes covers most small to medium lawns

  • String trimmer line is .065" dual line, may require frequent advancement
Detailed Review

The Greenworks 40V 21" Brushless Cordless Self-Propelled Electric Lawn Mower with String Trimmer is a comprehensive lawn care solution for homeowners seeking a gas-free, low-maintenance alternative. This combo kit includes a 21" self-propelled mower and a 12" string trimmer, both powered by a single 5.0Ah battery and charger. The mower features a durable steel deck and a highly efficient brushless motor that delivers more torque, quieter operation, and extended lifespan compared to brushed motors.

This setup is best suited for small to medium-sized lawns up to about 5,000 square feet. The self-propelled rear-wheel drive provides excellent traction on slopes and uneven terrain, making mowing less physically demanding. The 3-in-1 design allows you to choose between rear bagging, side discharge, or mulching, giving you flexibility based on your lawn's needs. The single lever 7-position height adjustment ensures you can achieve the perfect cut in any condition.

One of the standout features is the vertical storage capability, which saves up to 70% more space in your garage or shed. The included 12" string trimmer with a .065" dual line auto-feed head and variable speed trigger allows for precise trimming around flower beds, fences, and other obstacles. The entire system is virtually maintenance-free with no gas, oil, or emissions, and it starts instantly with the push of a button.

However, there are a few drawbacks to consider. The 80-pound weight can be cumbersome when lifting the mower for vertical storage, especially for lighter users. Some customers report that the battery may not last for the entire lawn if the grass is thick or if you frequently stop and start the mower. In such cases, purchasing an additional battery is recommended. The trimmer line is on the thinner side and may need frequent advancement during use.

Overall, the Greenworks 40V combo offers excellent value for those looking to switch from gas to battery-powered equipment. It provides reliable performance, convenience, and space-saving storage, making it a solid choice for maintaining a neat and tidy lawn without the hassle of gas and oil.

Build quality is solid with a metal construction and durable PVC wheels that glide over rough ground.

Buying Guide for 2026

Power Source and Cutting Torque

All 5 models in this roundup run on rechargeable lithium-ion batteries, which means no gas, no oil changes, and no carburetor maintenance. The key differentiator is cutting torque. The EGO POWER+ 21″ Select Cut Self-Propelled Lawn Mower Bundle with 7.5Ah and 5.0Ah Batteries (LM2135SP) leads the group with up to 7.0 ft-lbs of torque, while the EGO POWER+ 21-Inch Self-Propelled Cordless Lawn Mower with 56V 6.0Ah Battery and 320W Charger – LM2114SP delivers up to 6.0 ft-lbs. The Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower with 4.0Ah Battery and Rapid Charger uses an 80V platform and a brushless motor, which gives it strong acceleration and consistent power in thick grass, though its 4.0Ah battery is smaller than the EGO bundles.

If you regularly cut dense or slightly overgrown grass, prioritize higher torque and a brushless motor. All three models here use brushless motors, but the EGO LM2135SP has the most headroom for demanding conditions. For lighter weekly maintenance, the lower-torque EGO LM2114SP is still more than capable and often feels easier to maneuver.

Cutting Width and Height Adjustment

A 21-inch deck is the standard for mid-sized residential yards, and all 5 picks here use that width. The larger deck reduces the number of passes needed compared with smaller 18-inch or 19-inch mowers, which is why these models are a strong fit for quarter-acre to half-acre lawns. If your yard is especially tight or has narrow gates, check out our best affordable lawn mowers guide for additional sizing context.

Height adjustment is another practical detail. The EGO LM2114SP offers 7-position cutting height adjustments from 1.25 to 4 inches, which covers everything from a close trim to a taller, healthier cool-season cut. The other two models also provide multi-position height settings, but the LM2114SP gives the clearest range for users who change cutting height frequently during the growing season.

Self-Propelled vs Push and Speed Control

Self-propelled mowers reduce the effort required on slopes and larger lawns, but the control style matters. The EGO LM2135SP uses Touch Drive technology, letting you engage the self-propel function with your palm and adjust speed with a dial. The EGO LM2114SP has a dual-toggle handleset, so you can engage the drive with either hand. The Greenworks model uses rear-wheel drive with variable speed control, which provides strong traction on uneven ground.

If you have a hilly yard, rear-wheel drive often feels more stable because the drive wheels stay planted when the front of the deck lifts over bumps. If you prioritize one-handed comfort and fine speed adjustments, the Touch Drive system on the LM2135SP is the most refined option in this group.

Bagging, Mulching, and Side Discharge

Versatility is important because grass conditions change throughout the season. The Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower with 4.0Ah Battery and Rapid Charger offers a 4-in-1 system: mulching, bagging, side discharge, and turbo leaf pickup. That makes it a useful option in fall when leaves accumulate quickly. The EGO LM2135SP includes the Select Cut Multi-Blade system with mulching, high-lift bagging, and extended runtime lower blades, so you can tailor the cut to the task. The EGO LM2114SP has a 3-in-1 function covering mulching, bagging, and side discharge.

If leaf pickup is a seasonal priority, the Greenworks model has an edge. If you want the most customizable cut quality, the Select Cut system on the LM2135SP is the stronger pick. For straightforward lawn maintenance, the LM2114SP covers all the basics without extra complexity.

Runtime and Battery Capacity

Battery runtime is one of the most common concerns for battery powered self-propelled lawn mowers shoppers. The EGO LM2135SP bundle includes a 56V 7.5Ah battery plus an extra 5.0Ah battery, giving you up to 60 minutes of runtime on the main battery and a ready backup when the first charge runs out. The EGO LM2114SP includes a 56V 6.0Ah battery with up to 50 minutes of runtime. The Greenworks model includes an 80V 4.0Ah battery and is rated for up to half an acre per charge, though actual runtime varies based on grass condition and terrain.

For larger lawns, the dual-battery EGO LM2135SP bundle is the most practical because you can swap batteries instead of waiting for a recharge. For smaller yards, the single-battery options are lighter and often more budget-friendly. If you plan to store your mower during the off-season, our best self propelled lawn mowers for hills guide covers the steps that help protect battery health.

Why Trust Our Reviews

We evaluate battery powered self-propelled lawn mowers by comparing manufacturer specifications, real-world user feedback, and the practical tradeoffs that matter most in residential lawn care. Our process focuses on torque, battery capacity, deck width, height adjustment range, and self-propel control rather than marketing claims. We also consider how each model performs across common tasks like mulching, bagging, and side discharge.

We do not claim hands-on testing of every unit. Instead, we aggregate patterns from verified user reviews and spec sheets to highlight consistent strengths and weaknesses. As an Amazon affiliate site, we may earn a commission from qualifying purchases, but that never influences which products we include or how we rank them. Our goal is to give you a clear, balanced view so you can choose the right mower for your yard.

Our Final Picks for 2026

Best Overall: EGO POWER+ 21″ Select Cut Self-Propelled Lawn Mower Bundle with 7.5Ah and 5.0Ah Batteries (LM2135SP)

The EGO LM2135SP bundle is the strongest all-around pick in this roundup because it pairs up to 7.0 ft-lbs of cutting torque with two batteries, giving you extended runtime and a backup power source. The Select Cut Multi-Blade system lets you switch between mulching, high-lift bagging, and extended runtime blades, while Touch Drive self-propel control makes speed adjustments feel smooth and responsive. This model is a natural fit if you want gas-like power without the maintenance, and it pairs well with the guidance in our best cordless self propelled lawn mowers comparison for buyers who are still weighing power source options.

View on Amazon.com

Skip this if you only mow a small, flat yard and do not need the extra battery or the Select Cut blade system.

Best Value: Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower with 4.0Ah Battery and Rapid Charger

The Greenworks 80V model offers a practical balance of power and versatility, with a brushless motor, rear-wheel drive, and a 4-in-1 system that covers mulching, bagging, side discharge, and turbo leaf pickup. Its LED headlight is a useful extra for early morning or late evening mowing, and the 80V platform is compatible with a wide range of Greenworks tools. For homeowners who want a capable self-propelled mower without paying for a premium dual-battery bundle, this is one of the most sensible choices in the battery powered self-propelled lawn mowers category.

View on Amazon.com

Skip this if you need the longest possible runtime from a single included battery, since the 4.0Ah pack is smaller than the EGO bundles.

Best for Simple, Reliable Cutting: EGO POWER+ 21-Inch Self-Propelled Cordless Lawn Mower with 56V 6.0Ah Battery and 320W Charger – LM2114SP

The EGO LM2114SP is the most straightforward option in this group, offering up to 6.0 ft-lbs of torque, a 7-position height adjustment range, and a dual-toggle handleset that works for left- or right-handed users. Its 3-in-1 mulching, bagging, and side discharge setup covers the core mowing tasks without extra blades or accessories to manage. If you want a dependable self-propelled cordless mower that is easy to operate and maintain, this model is a strong contender. For more context on how it fits into the broader market, see our best self propelled walk behind string trimmer guide, which compares gas and battery approaches.

View on Amazon.com

Skip this if you want the highest torque or a second battery included, because the LM2135SP bundle is stronger in both areas.

Frequently Asked Questions

Which battery powered self-propelled lawn mowers should I buy in 2026?

The right choice depends on your yard size and how much runtime you need. The EGO LM2135SP bundle is the best fit for larger lawns or anyone who wants a backup battery, while the Greenworks 80V model offers strong value and leaf pickup versatility. The EGO LM2114SP is ideal for simpler, reliable weekly mowing.

How long do battery powered self-propelled mowers run on a single charge?

Runtime varies based on battery capacity, grass thickness, terrain, and whether you use self-propel continuously. The models in this roundup range from roughly 50 to 60 minutes on their primary batteries, with the EGO LM2135SP bundle offering an extra battery for extended sessions.

Are battery powered self-propelled mowers powerful enough for thick grass?

Yes, modern brushless motors and higher-voltage batteries have closed much of the gap with gas. The EGO LM2135SP delivers up to 7.0 ft-lbs of cutting torque, which is enough for most residential lawns, including moderately thick or damp grass. For very overgrown conditions, mowing more frequently and using a high-lift blade helps maintain cut quality.

Can I use these mowers for mulching and bagging?

All three models support mulching and bagging. The Greenworks model adds a turbo leaf pickup mode, and the EGO LM2135SP includes interchangeable lower blades for different cut tasks. The EGO LM2114SP provides a straightforward 3-in-1 setup for mulching, bagging, and side discharge.

What maintenance do cordless self-propelled mowers require?

Battery mowers require far less maintenance than gas models. You should keep the deck clean, sharpen or replace blades as needed, and store the battery in a cool, dry place during the off-season. For a complete seasonal checklist, see our best self propelled lawn mowers for hills guide.
