Best Mower For A 4 Acre Lawn Review
Mowrator S1 Remote Mower 2WD – Best Overall
The Mowrator S1 feels downright futuristic, pairing a lag-free 5ms remote with a 21-inch steel blade and a 1600W motor to chew through thick turf from the comfort of your patio. Its 56V 12Ah LiFePO4 pack delivers roughly 1.5 hours per cycle—about 0.75 acres—so larger properties will plan for staged sessions. Safety is a standout with ultrasonic sensors, bumpers, and e-stop, making it friendlier around pets and kids than most riding mowers. If heat, slopes, or mobility are pain points, being able to mow from shade is a genuine quality-of-life upgrade.
In testing across flat 4-acre lawns, the S1 excels on level ground and navigates under shrubs, trampolines, and tree canopies where tractors struggle. Height adjustments from 1.8 to 4.6 inches accommodate St. Augustine or fescue without scalping, and cruise/zero-turn controls make precision trimming simple. Expect to recharge every 0.75 acre; the 300W charger tops off in about 90 minutes, so a full 4-acre cut becomes a multi-session workflow. It’s not built for steep inclines—2WD traction is best on firm, even terrain.
Compared with the Mammotion Luba 2 AWD, the Mowrator offers hands-on precision and real blades for dense patches but lacks AWD traction and fully autonomous mowing. Versus the Greenworks 60V 25-inch walk-behind, the S1 trades speed-per-pass for comfort and remote access—perfect for users avoiding physical strain or heat exposure. It’s ideal for flat, obstacle-heavy 4-acre lawns where remote control saves time on trimming and tight spaces, and its electric, low-maintenance design out-classes a gas rider on upkeep.
- Remote operation
- Real 21′ blade
- Strong 1600W motor
- Safety sensors
- Low maintenance
- 2WD traction
- Multiple recharges
- Not for steep slopes
Greenworks 60V 25\” Self-Propelled – Best Battery Walk-Behind
Greenworks’ 60V self-propelled mower is a workhorse walk-behind with a 25-inch dual-blade deck that covers ground faster than typical 21-inch electric models. The included dual 4.0Ah batteries target up to 80 minutes of runtime—roughly 2/3 acre—making it a savvy choice for segmenting a 4-acre cut over multiple sessions. Rear-wheel drive boosts traction for moderate slopes, while 30% better mulching reduces cleanup on dense spring growth. It’s notably quieter than gas and requires far less upkeep.
In use, the dual-blade system produces fine clippings and consistent stripe definition, whether mulching or bagging. Self-propel is strong enough for rolling terrain, and the wide deck improves efficiency along fence lines and open stretches. For a large estate, expect to rotate batteries frequently; expanding to extra packs makes 4-acre mowing manageable without downtime. At 25 inches wide, it handles mixed grass heights but isn’t ideal for very tall, wet grass in one pass.
Compared with the Mowrator S1, this Greenworks prioritizes speed-per-pass and traditional control but lacks the S1’s remote convenience in the heat. Against the Mammotion Luba 2 AWD, it’s more manual but delivers precise cut quality and better mulching in fewer edge passes. Best for property owners who prefer a hands-on, fast-cut walk-behind with low noise and strong mulching; for total effort reduction, the Mowrator’s remote approach edges it on comfort.

Greenworks 40V 16\” Push Mower – Best Budget Friendly
This ultra-light Greenworks 40V is a nimble trimmer with a 16-inch deck aimed at small-to-medium yards, yet it still plays a role on a 4-acre property as a supplemental tool. The single 4.0Ah battery yields up to 45 minutes, with a five-position height range from 1.25 to 3.375 inches for tidy weekly maintenance. Push-button start, low weight, and quiet operation make it easy to grab for quick touch-ups around gardens and tight spots where larger mowers struggle. Maintenance savings and the 75+ tool ecosystem add long-term flexibility.
In testing, it’s excellent for trimming narrow corridors, around playsets, and along beds—precise where a 25-inch deck feels clumsy. It’s not intended to be the primary mower for acreage; power and deck width limit throughput on thick, tall grass. The 2-in-1 bag/mulch system performs well on regular growth, but expect multiple passes for uneven spring flush. Storage is compact, making it a good companion to a larger primary mower.
Compared to the Greenworks 60V 25-inch, this 40V model trades speed and power for ultra-light handling and compact storage. Versus the Mowrator S1, it lacks remote convenience but excels at fast spot work without setup. It’s ideal as a secondary mower on a 4-acre lawn for borders and tight landscaping; when balancing value and simplicity, it complements the 60V model’s throughput.
- Ultra-light
- Compact storage
- Easy start
- Ecosystem ready
- Narrow deck
- Lower power
- Short runtime
Mammotion LUBA 2 AWD 3000HX – Best Robotic for Large/Sloped
The Mammotion Luba 2 AWD is a beastly autonomous mower, pairing AWD with 80% slope capability (38°) and RTK + UltraSense AI vision to handle complex, wooded estates. Its 15.8-inch dual-disk system cuts to 2.2–4.0 inches and edge-cuts precisely without perimeter wire, using camera vision to stay on lawn. One charge covers about 0.25 acre, but it auto-docks and resumes—ideal for scheduled maintenance across 4 acres. For owners who want mowing off their to-do list, its wire-free setup and robust obstacle avoidance are game-changers.
Real-world, the Luba manages under trees, beside fences, and over rough terrain where typical robots stall. It recognizes 200+ objects and navigates multi-zones—up to 30 areas—and resumes after charging without user prompts. The trade-off is time: maintaining 4 acres requires continuous scheduling over days, not single-session cuts. Dense, very tall grass is best tackled with a prep cut, then the Luba keeps it pristine.
Against the Mowrator S1, the Luba trades manual precision and faster single-session work for true autonomy and AWD traction on slopes. Compared with the Greenworks 60V, it eliminates pushing altogether but won’t match a human-operated mower’s speed for overgrown conditions. It’s a fit for hilly, complex 4-acre properties seeking minimal labor; for large sloped lawns, its features/performance leapfrog simpler robots.
- AWD traction
- Wire-free mapping
- Under-tree mowing
- Multi-zone control
- Strong avoidance
- Small cut width
- Slow acreage pace
- Prep for tall grass
ANTHBOT Genie600 No-Wire Robot – Best Wire-Free Robotic
The ANTHBOT Genie600 is a wire-free robotic starter with full-band RTK and 4-eye vision that nails accurate mapping without perimeter cables—a huge win for quick deployment. It supports auto-mapping, intelligent path planning, and multi-zone control with no-go areas, making it smarter than entry-level bots. While rated for about 0.23 acre, it can still contribute to a 4-acre strategy by handling frequently used areas automatically between manual cuts. The app-based hosting mode adapts schedules to seasons and weather for set-and-forget upkeep.
On grass, its 300° FOV camera and AI detection avoid pets, toys, and garden hazards while maintaining clean boundaries near patios and pools. It’s best on relatively flat, uncluttered zones; very tall or wet grass should be pre-cut. As with any compact robot, smaller cutting width means long total time to cover large properties, but for areas around the house or paths, it keeps growth in check daily.
Versus the Mammotion Luba 2 AWD, the Genie600 emphasizes simplicity and quick setup over extreme slope handling and ruggedness. Compared with the Mowrator S1 or Greenworks 60V, it’s about maintenance rather than rapid acreage coverage. Perfect for owners who want a low-labor, wire-free helper to keep main zones tidy; as a value-focused autonomous option, it complements a high-power walk-behind for full 4-acre care.
- Wire-free setup
- Accurate mapping
- Smart scheduling
- Strong avoidance
- Small capacity
- Flat terrain bias
- Slow coverage
