7 Best Self-Propelled Lawn Mowers for Large Decks 2025

Commanding and refined, the EGO Power+ LM2200SP flexes with up to 11.1 ft-lbs of torque and blade speeds to 3,350 RPM, giving a crisp cut that rivals premium gas. The 22-inch cast aluminum deck is not only rigid and rust-proof—it’s backed by a lifetime deck warranty, a rarity in cordless. EGO’s Select Cut multi-blade system lets you swap lower blades for high-lift bagging or high-performance mulching, solving the usual ‘electric can’t bag well’ complaint.

In testing across thick fescue and slightly overgrown Bermuda, it maintained blade speed reliably and didn’t surge, a common issue with smaller decks. The Touch Drive self-propel dial allows fingertip pacing, while a recommended 56V 10Ah battery nets up to about 70 minutes in ideal conditions—expect less in tall or wet growth. The 22-inch deck covers ground fast, though the aluminum chassis adds heft that’s felt when maneuvering in tight beds.

Against the Greenworks 40V 21-inch, the EGO offers more cutting torque, a larger deck, and better bagging thanks to its dual-blade stack, but it’s heavier and requires separately purchased batteries. Compared with the Yardmax 22-inch gas, EGO trades endless runtime for quieter operation and near-zero maintenance. It’s ideal for owners seeking a large-deck self-propelled cordless that truly replaces gas; feature-for-feature, it outmuscles Greenworks with superior runtime potential and cut quality.

Punchy and practical, the Yardmax 22-inch brings 201cc of grunt with an industry-first CVT 6-speed that syncs pace to your stride. The 16-gauge stamped steel deck and Maxflow spiral design aid airflow, improving mulch dispersion and bag fill. Big 11-inch rear wheels and spiked rubber tread deliver confident traction on flat, sloped, and uneven yards.

In real-world mowing, the Yardmax powers through thick spring growth without bogging and keeps a consistent line thanks to RWD. The single-lever height adjust spans 1.38–3.55 inches, making it easy to flip between manicure and drought-friendly heights. Cleaning is straightforward with the deck wash port; noise and vibration are higher than electric, but the double ball-bearing wheels smooth out rolling.

Compared to the PowerSmart 22-inch (150cc), Yardmax’s larger 201cc engine and CVT drive offer better hill performance and speed control, though it’s a touch heavier. Versus the SENIX 22-inch models, Yardmax emphasizes traction and deck airflow over ultra-light maneuverability. For shoppers wanting a large-deck self-propelled mower that balances control, durability, and cut efficiency, it delivers stronger performance than the smaller-engine PowerSmart at similar feature depth.

Nimble yet capable, the SENIX LSSG-H2 pairs a Briggs & Stratton 163cc EXi675 with a 22-inch steel deck for quick coverage without feeling cumbersome. The rear-wheel drive and variable speed help you maintain momentum over bumpy ground, while the ergonomic handle keeps fatigue in check. Vertical storage and a fold-down handle cater to garages where space is tight.

On tall ryegrass and patchy, uneven yards, it holds speed and produces a clean cut from 1.25 to 4 inches with a simple single-lever adjustment. The included 19-gallon bagger fills evenly; mulching is effective, though wet clippings benefit from a slower pace. A washout port makes cleanup painless, but front-wheel-drive would be easier for frequent pivoting around beds.

Versus the SENIX RWD single-speed sibling, this model’s variable pace offers better control on mixed terrain. Compared to the Yardmax 201cc, it sacrifices raw torque for lighter handling and easier storage. Ideal for homeowners who want a large-deck mower that threads between obstacles and tackles small-to-medium yards efficiently; in feature balance, it’s more maneuverable than Yardmax but not as forceful in dense growth.

Surefooted and steady, this SENIX 22-inch leans on rear-wheel drive and a 163cc Briggs & Stratton EXi675 for consistent traction on slopes. The 3-in-1 deck supports mulching, side discharge, and rear bagging, and the 19-gallon bagger comes in the box. Its single-speed self-propel is simple and reliable, appealing to users who prefer set-and-forget operation.

In use, the mower tracks well on gradients and churns through weekly trims without needing multiple passes. Height adjustment from 1.25 to 4 inches suits seasonal shifts, and the 8-inch front/11-inch rear wheels roll confidently over ruts. The washout port speeds cleaning; mulching dense, damp patches may require slowing down, and single-speed pacing won’t fit every stride.

Compared to the SENIX LSSG-H2 variable-speed, this model is better on slopes thanks to predictable traction but gives up pacing flexibility. Against the Yardmax 201cc, it’s lighter and easier to manage, though not as powerful in overgrowth. It’s a smart pick for users prioritizing hill stability and straightforward controls; relative to the LSSG-H2, you trade customization for surefooted slope performance.

Compact bruiser energy: this PowerSmart 22-inch couples a 150cc Briggs & Stratton EX625 with RWD to push through thicker lawns better than its size suggests. The heavy-duty blade and 3-in-1 setup handle mulching, bagging, or discharge, while the single-lever 1.5–3.9-inch height range makes quick adjustments easy. No-tool assembly and straightforward controls get you mowing fast.

In real-world cuts, it finishes a suburban quarter-acre efficiently, and the deck’s airflow produces fine clippings for healthier mulch layers. On steeper inclines, RWD keeps traction, though the smaller engine can slow in very tall, wet grass—manageable with a slower pace. The 1.4-bushel bag empties easily; noise and vibration are typical for its class.

Compared to the Yardmax 201cc, PowerSmart gives up torque but wins on maneuverability and lighter feel, making it easier around landscaping. Versus the SENIX 163cc units, it’s similar in deck size but slightly less forceful in overgrowth. Best for homeowners seeking a large-deck value mower with capable RWD and simple operation; it’s easier to handle than Yardmax, though not as muscular in dense turf.

Quiet confidence defines the Greenworks 40V 21-inch, packing a brushless motor and durable steel deck into a remarkably approachable package. The included 5.0Ah battery supports up to about 45 minutes in ideal conditions, and RWD self-propel boosts traction on uneven lawns. Vertical storage frees up garage space, and maintenance is nearly zero—no gas, no oil, instant starts.

In testing across mixed turf, the 7-position single-lever height adjust dials a neat cut, and the 3-in-1 design mulches or bags reliably at moderate growth. It’s a touch narrower at 21 inches, so coverage is slightly slower than 22-inch decks, and heavy, wet grass can tax runtime. Noise is pleasantly low, making early-morning mowing neighbor-friendly.

Compared to the EGO LM2200SP, Greenworks is lighter and easier to stash, but it can’t match EGO’s torque, 22-inch deck, or Select Cut bagging performance. Against gas units like Yardmax, it trades endless runtime for ease and serenity. Ideal for buyers wanting a budget-friendly electric self-propelled with strong everyday performance; feature-for-feature, EGO delivers more cutting power and deck size, while Greenworks wins on simplicity and included battery.

Efficient and straightforward, this 21-inch PowerSmart uses a 140cc Briggs & Stratton with rear-wheel drive to keep traction over rough patches. The 3-in-1 deck and single-lever height range of 1.5–3.9 inches make it adaptable for seasonal growth. Its 10-inch rear wheels help it roll smoothly while staying compact for smaller sheds.

In practice, it’s a tidy weekly cutter, handling typical suburban turf without bogging, though very tall or damp grass may require a second pass. The steel deck feels sturdy, and bagging performance is solid for its size. It’s a touch narrower than 22-inch models, so larger lawns will take longer—balanced by easier maneuvering around beds and fences.

Compared to the PowerSmart 22-inch 150cc, this model is lighter and more maneuverable but covers less ground per pass and has slightly less cutting force. Versus Greenworks 40V, you gain unlimited runtime and stronger dense-grass performance at the cost of noise and maintenance. It suits budget-minded buyers who want reliable self-propelled traction in a manageable footprint; relative to the 22-inch PowerSmart, you trade speed for agility.
