Best 42 Inch Zero Turn Lawn Mower Review
EGO 42″ Zero Turn Riding Mower – Best Overall
This game-changing electric beast redefines what it means to mow without gas—delivering 22 horsepower-equivalent power and 8 MPH speeds with zero emissions. The 42-inch stamped steel deck slices through thick grass with surgical precision, while the four 56V 10.0Ah ARC Lithium batteries provide enough juice to tame up to 2 acres on a single charge. With an intuitive LCD interface, you can fine-tune your ride across three driving modes—Standard, Control, and Sport—making it a precision instrument for lawn perfectionists who hate noise, fumes, and maintenance.
In real-world testing, the ZT4204L handles uneven terrain and dense overgrowth like a champ, thanks to its responsive zero-turn steering and aggressive traction. The 10 cutting height positions (1.5” to 4.5”) offer granular control, and the 3-in-1 functionality (mulching, bagging, side discharge) adapts to any lawn condition. Recharging takes just two hours with the included Z6 wall charger, minimizing downtime—ideal for weekend warriors or property managers. However, while it conquers flat to moderate slopes with ease, steep or wet inclines demand cautious handling, and the heft of the mower limits storage options in compact sheds.
Compared to gas-powered rivals like the Husqvarna Z242F, the EGO ZT4204L trades raw fuel endurance for clean, quiet, and instant power delivery—perfect for eco-conscious homeowners with medium to large yards. It’s more refined than the Greenworks 80V models, offering better battery capacity and a smoother ride experience. While pricier than traditional mowers, its low maintenance and smart customization make it a future-proof investment. For those prioritizing performance, silence, and sustainability, this EGO model outshines others in both innovation and execution.
- Zero emissions
- 8 MPH speed
- 2-acre runtime
- Customizable drive modes
- Fast 2-hour recharge
- Heavy build
- Not ideal for wet slopes
- Limited tight-space storage
Greenworks 80V 42″ Zero Turn Mower – Best Power
Meet the muscle car of electric mowers—the Greenworks 80V ZTR doesn’t just match gas; it aims to dominate it with 32 horsepower-equivalent output and a 17,000 FPM blade tip speed that never dips, thanks to Cyclone Cut Technology. The reinforced 12-gauge steel 42-inch deck powers through tall grass without bogging down, while the dual-port rapid chargers keep battery downtime minimal. With 8 MPH top speed and 15° hill-climbing ability, this mower tackles challenging terrain like a pro, making it the top pick for power seekers who refuse to compromise.
On test runs, the mower excelled on overgrown lawns and sloped yards, maintaining consistent cut quality even in thick patches where lesser mowers stall. The constant blade speed ensures clean, even cuts that promote lawn health, while the rear dump bed with hydraulic assist is a game-changer for hauling debris or mulch—no other electric model offers this. However, the 5.0Ah batteries provide only up to 2 acres per charge, which may fall short for larger properties without extras. And while the build is rugged, the ride can feel stiff on rocky or bumpy ground, lacking advanced suspension.
Against the EGO ZT4204L, this Greenworks model trades some refinement for raw cutting aggression and payload utility. It’s less about comfort and more about brute force, positioning it as the go-to for landscapers or serious DIYers with tough mowing conditions. While it lacks EGO’s customizable driving modes or fast recharge tech, its Cyclone Cut system and dump bed offer unique advantages. For users who need maximum power and hauling capability, this Greenworks mower delivers unmatched electric torque and utility—even if it sacrifices a bit of finesse.
- 32 HP equivalent
- Cyclone Cut Technology
- Rear dump bed
- 15° slope handling
- Rapid charging
- Stiff ride quality
- Limited battery life extension
- No drive mode customization
Greenworks 80V 42″ Zero Turn +Combo – Best Value
This package isn’t just a mower—it’s a complete power ecosystem, and the bonus 6-piece tool kit instantly elevates its value proposition. The core mower matches its sibling model with 32 horsepower-equivalent power, Cyclone Cut Technology, and a 17,000 FPM blade speed that slices cleanly through dense grass. Add in high-intensity LED headlights and a premium high-back padded seat with foldable armrests, and you’ve got a machine built for long mowing sessions in comfort and visibility, even at dawn or dusk.
Performance-wise, it mirrors the B0DD6JMGDS: excellent on flat to moderately sloped lawns, with consistent cutting power and 8 MPH speed, but limited to 2 acres per charge on the included 5.0Ah batteries. The 600W charger is slower than the dual-port version, meaning longer waits between mows for heavy users. Still, the rear dump bed with 200 lb. hydraulic assist remains a standout for hauling mulch or yard waste—a rare feature in this class. While the ride quality is firm, the added seat comfort helps absorb vibration better than most electric ZTRs.
What sets this model apart is the incredible bundle: getting a drill, impact driver, circular saw, tire inflator, and more for roughly the same price as the non-bonus Greenworks model (and only slightly above the EGO) makes it a no-brainer for tool collectors or home renovators. Compared to the EGO ZT4204L, it trades slightly slower charging and less refined controls for greater utility and tool value. If you’re building a cordless workshop or want maximum bang for your buck, this Greenworks combo delivers exceptional overall value with serious cutting power.
- Bonus 6-piece tool kit
- Rear dump bed
- LED headlights
- Comfortable high-back seat
- 32 HP equivalent
- Slower 600W charger
- Firm ride on rough terrain
- Battery life not expandable
Husqvarna Z242F 42″ Zero Turn – Best Traditional
For traditionalists who trust proven gas-powered reliability, the Husqvarna Z242F is a workhorse built for durability and smooth operation. Its 21.5HP Kawasaki engine delivers consistent power without the range anxiety of battery models, while the hydrostatic transmission ensures buttery-smooth zero-turn maneuvers and excellent responsiveness across varied terrain. The 42-inch fabricated deck handles mulching, bagging, and side discharge (with kits sold separately), offering long-term versatility for serious lawn care. Plus, the patent-pending auto park brake enhances safety—engaging when levers are released, a smart touch for busy yards.
In real-world use, this mower shines on larger properties (2+ acres) where refueling beats recharging. It powers through thick grass and uneven ground with ease, and the 3.5-gallon fuel tank supports extended mowing sessions. However, without included mulching or bagging kits, you’ll need to spend extra to unlock full functionality—making the upfront value feel incomplete. The ride is solid but basic, with minimal comfort features compared to premium electric models. And while it’s low-maintenance for a gas mower, it still demands oil changes, fuel storage, and seasonal prep.
Against the EGO ZT4204L, the Z242F wins on run time and fuel availability, but loses on noise, emissions, and tech features. It’s a no-nonsense, dependable performer—ideal for users who prioritize long-term reliability and low cost of ownership over eco-friendliness or quiet operation. For those with large, open lawns and a garage setup for gas equipment, this Husqvarna offers uncomplicated power and commercial-grade toughness at a competitive entry-level price.
- 21.5HP Kawasaki engine
- Hydrostatic transmission
- Auto park brake
- 3.5-gallon fuel tank
- Proven gas reliability
- Mulching kit not included
- Bagger sold separately
- Noisy and emits fumes
How to Choose the Best 42-Inch Zero Turn Lawn Mower
When selecting a 42-inch zero turn lawn mower, focus on these key features to ensure you get the right model for your needs:
1. Power & Performance
- Gas vs. Electric: Gas mowers (e.g., Husqvarna Z242F) offer traditional power, while electric models (e.g., EGO 42″) provide quiet, eco-friendly operation with battery life up to 2 acres per charge.
- Horsepower Equivalent: Electric mowers like Greenworks 80V deliver 32HP equivalent—ideal for heavy-duty mowing.

Why It Matters: Longer runtime reduces interruptions; quick charging keeps your mower ready.
3. Cutting Deck & Adjustability
- Deck Size: A 42-inch deck balances maneuverability and coverage.
- Cutting Height: Adjustability (1.5–4.5 inches, most models) suits different grass types.
- Deck Material: Stamped steel (EGO) or reinforced 12-gauge steel (Greenworks) for durability.
Why It Matters: A sturdy deck with flexible height options ensures a precise, even cut.
4. Comfort & Convenience
- Seat & Controls: Look for padded seats (Greenworks) and intuitive LCD interfaces (EGO).
- Extras: Rear dump beds (Greenworks) or LED headlights add utility for larger properties.
Why It Matters: Comfortable operation reduces fatigue during long mowing sessions.
Other Features to Consider:
- Transmission: Hydrostatic (Husqvarna) for smooth handling.
- Attachments: Mulching/bagging kits (sold separately on some models).
- Warranty: 3-year coverage (Husqvarna) vs. shorter terms.
Choose based on your yard size, terrain, and preference for gas/electric power. Budget-friendly options like Ariens IKON sacrifice extras but deliver core performance.
