8 Best Self-Propelled Electric Mulching Lawn Mowers 2025

Muscular yet refined, the Greenworks 60V 25-inch is a mulching powerhouse that finally makes going electric feel like an upgrade. The wide 25-inch deck and dual-blade system promise up to 30% better mulching, and the rear-wheel-drive self-propel makes hills feel lighter. With two 4.0Ah batteries and a dual-port rapid charger, it’s built for uninterrupted sessions and up to 80 minutes of runtime in ideal conditions. If you’re tired of gas noise and fumes, its 60% quieter operation is a relief.

In testing, the 25-inch deck covers ground noticeably faster than 21-inch models, ideal for 1/2–2/3 acre lots. The dual blades finely chop clippings, leaving a cleaner finish and fewer clumps in dense spring growth. Rear-wheel drive maintains traction on slopes, and the aluminum handles feel sturdy over uneven terrain. It can struggle a bit if you push max height in very wet, overgrown grass, but a slower pace solves it.

Against the EGO LM2134SP-2, the Greenworks 60V 25-inch trades ultimate runtime for wider swath and stronger mulching in one pass. Compared with the Greenworks 40V 21-inch, it’s heavier but notably more powerful and efficient on larger lawns. It’s ideal for homeowners who want premium mulching, bigger coverage, and confident hill handling; if you want the best cut-per-pass ratio, this edges out the 21-inch EGO on efficiency per stripe while staying more approachable in price-to-feature value than EGO’s premium kit.

The Greenworks 40V 21-inch strikes a sweet spot for budget-minded buyers who still want self-propel and mulching. Its brushless motor and steel deck deliver clean cuts with less vibration, and the 3-in-1 system handles bagging, mulching, or side discharge. You also get vertical storage to reclaim garage space and a 7-position single-lever height adjuster that makes dialing in cut height painless.

In the yard, expect up to 45 minutes from the included 5.0Ah battery depending on grass thickness and pace. The 21-inch deck suits small-to-medium lawns, and rear-wheel drive helps maintain line control on bumps. Mulching performance is solid for weekly cuts; if you routinely tackle tall, damp grass, it benefits from slower passes. The mower’s lighter weight makes it easy to maneuver around trees and beds.

Compared with the Greenworks 60V 25-inch, the 40V is more compact and easier to store, but has less power and coverage per pass. Versus the MightyMow 40V, Greenworks offers a more mature ecosystem and better refinement, though MightyMow includes a larger battery package. Best for first-time electric buyers or smaller yards who want self-propel convenience without overpaying; it undercuts the EGO LM2135SP on features-to-cost while remaining practical.

The EGO LM2134SP-2 feels athletically tuned for premium lawn care with its Select Cut multi-blade system and intuitive Touch Drive control. With two 56V 6.0Ah ARC batteries, it claims up to 100 minutes of runtime, making it a long-haul champ for larger properties. The adjustable speed range (0.9–3.1 MPH) and 8-position height adjuster provide precise control for different grass types and seasons.

On turf, the Select Cut system lets you prioritize mulching finish or bagging airflow, and the 21-inch deck excels in manicured lawns where cut quality is paramount. The high-efficiency brushless motor keeps noise down while delivering consistent torque through thick spots. It handles slopes competently, though the self-propel tug is gentler than some aggressive RWD systems. In heavy, wet, overgrown grass, a slower walking speed preserves blade RPM and finish.

Compared to the Greenworks 60V 25-inch, EGO’s cut quality and runtime lead, while Greenworks covers more ground per pass and has a stronger mulching bias. Versus the EGO LM2135SP, this dual-battery kit stretches runtime and reduces charging interruptions. It’s ideal for homeowners prioritizing premium finish and long sessions; in a features-versus-value lens, it offers more runtime headroom than Greenworks 40V while competing closely with Greenworks 60V for overall capability.

The Greenworks 60V 21-inch packs 4-in-1 versatility into a nimble frame that’s easy to live with. You get mulching, bagging, side discharge, and a turbo leaf pickup mode, backed by a quiet brushless motor and LED headlights for dusk sessions. With two 4.0Ah batteries and dual-port charging, it’s a practical step up from entry-level rigs without feeling overbearing.

In practice, the 21-inch deck is ideal for small-to-medium lawns with mixed terrain. Rear-wheel drive provides sure-footed traction on slopes, and the adjustable pace lets you fine-tune ground speed to maintain blade RPM in tougher patches. Mulching quality is strong for weekly maintenance, and the turbo pickup helps clear light leaf litter between bagging days. Runtime is solid, though thicker grass can shorten it, as expected.

Against the Greenworks 60V 25-inch, this model trades raw coverage for agility and storage friendliness while keeping the same ecosystem benefits. Compared with the Greenworks 40V 21-inch, it offers stronger torque and better performance in dense turf. It’s best for homeowners wanting an adaptable, quiet mower that handles leaves and grass in one tool; feature-for-feature, it balances versatility and power better than most 21-inch competitors here.

If your lawn laughs at ordinary electrics, the Greenworks 80V 21-inch brings muscle for thick/tall grass. Its 80V system, brushless motor, and durable steel deck push through overgrowth with fewer bog-downs, and RWD with variable speed keeps traction steady. The 4-in-1 system adds mulching, bagging, side discharge, and turbo leaf pickup, plus LED lights for early or late cuts.

In real-world mowing, the 21-inch deck isn’t the widest, but the torque makes up for it when grass is wet or overdue. The self-propel feels assertive on slopes, and the steel deck shrugs off knocks around borders. Expect around 1/2-acre coverage per charge depending on pace and grass conditions; for heavy mulching in dense turf, slower pacing elevates cut quality.

Versus the Greenworks 60V 21-inch, this 80V variant offers more grunt but similar deck width and slightly higher weight. Compared to EGO LM2135SP, the Greenworks 80V leans into raw power, while EGO emphasizes polish and runtime. Best for users with tough, fast-growing lawns who want a clean mulch finish without gas; power-to-performance stacks favorably over the 40V budget pick in heavy conditions.

The EGO LM2135SP nails the runtime-to-performance equation for demanding homeowners. With a 56V 7.5Ah ARC battery, you get up to 60 minutes per charge, and the Select Cut multi-blade system elevates mulching and bagging finish beyond typical single-blade designs. Touch Drive puts precise speed control at your fingertips, and LED headlights extend usable hours.

During testing, the 21-inch deck yielded tight stripes and a crisp mulch with weekly growth on cool-season grasses. The high-efficiency brushless motor holds RPM well through medium-thick patches, and the 0.9–3.1 MPH speed range suits flat and sloped sections alike. For taller or wet grass, drop a gear and let the blades do the work for consistent chop and airflow.

Compared to the LM2134SP-2 dual-battery kit, the LM2135SP is simpler to manage with one pack but offers shorter uninterrupted time. Against the Greenworks 60V 25-inch, EGO’s finish quality is a touch cleaner, while Greenworks covers more turf per pass. Ideal for users focused on cut quality and predictable runtime; for premium performance without going overboard, it hits a refined balance versus Greenworks 80V’s brute strength.

For EGO ecosystem owners, the LM2120SP is a smart body-only buy that still delivers serious torque—up to 6.0 ft-lbs—and EGO’s signature Touch Drive control. You get a 21-inch deck, LED headlights, and 3-in-1 functionality, with 7-position height adjust from 1.25 to 4 inches. Pair it with a 7.5Ah ARC battery for up to 60 minutes in ideal conditions.

On turf, this chassis mirrors EGO’s polished handling: smooth speed modulation, predictable RWD traction, and a tidy mulch for weekly maintenance. It’s quiet, easy to start, and holds RPM well through moderate-thick grass. For very tall or wet growth, pacing slower ensures clean discharge and prevents clumping.

Compared to the EGO LM2135SP, you’re sacrificing the included battery and charger but keeping the performance DNA—great if you already own packs. Versus the Greenworks 40V, it’s more powerful and refined, though total cost rises once you add batteries. Best for existing EGO users seeking to expand without duplicate chargers; as a platform play, it delivers higher performance than budget sets while letting you control total spend.

MightyMow’s 40V self-propel surprises with a value-packed kit: dual 8.0Ah batteries, dual charger, and a 21-inch steel deck spinning up to 3500 RPM. Its variable pace from 2.0–4.3 ft/s makes hill work manageable, and the 3-in-1 design covers mulching, bagging, and side discharge. For buyers prioritizing runtime per dollar, it checks the right boxes.

In the yard, the brushless motor keeps noise down while the boosted airflow improves bag fill and mulching uniformity on weekly cuts. Expect up to 60 minutes with self-propel on, or around 75 minutes pushing in lighter conditions. It handles typical suburban turf fine; dense, wet growth may require a slower pass to avoid clumping.

Against the Greenworks 40V, MightyMow wins on included battery capacity but lacks the broader tool ecosystem and long-term polish. Compared with EGO models, it can’t match Select Cut finish or Touch Drive finesse, but it’s far more accessible for first-timers. Ideal for budget-conscious homeowners who still want self-propel and solid mulching; feature for feature, it stretches runtime further out of the box than many entry rivals.
