3-in-1 (mulching, bagging, side discharge)
Power Source
Brushless 36V (18V X2)

This zero-emission powerhouse redefines what a commercial-grade electric mower should be—delivering gas-like performance without the noise, fumes, or maintenance. At its core, the Makita XML07PT1 runs on a dual 18V LXT battery system (36V total), with a 4-bay slot design that allows for two additional batteries, effectively doubling runtime. The commercial-grade steel deck stands up to daily abuse, while its 3-in-1 versatility—mulching, bagging, and side discharge—makes it a true workhorse for landscapers and serious homeowners alike.

In real-world testing across half-acre lawns with thick grass and uneven terrain, the mower delivered consistent cutting power and smooth handling, thanks to its well-balanced frame and efficient brushless motor. The 60–75 minute runtime with four 5.0Ah batteries is best-in-class for cordless models, and recharging is painless with Makita’s fast-charging ecosystem. However, while the brushless motor delivers strong torque, it can hesitate slightly when tackling wet, overgrown grass—something gas-powered rivals handle more effortlessly. Still, the low decibel output and instant start make it ideal for noise-sensitive areas like neighborhoods or early-morning jobs.

Compared to the Greenworks 82V model, the Makita trades a bit of peak power for superior battery modularity and brand reliability—a big win for pros who already use Makita tools. It’s not as budget-friendly as lower-voltage options, but if you demand professional durability, extended runtime, and seamless integration with an existing LXT battery fleet, this is the gold standard. For those weighing performance against ecosystem compatibility, the Makita offers unmatched synergy and long-term value.

Pros
  • Brushless motor
  • 4-battery support
  • Commercial steel deck
  • 3-in-1 mowing
  • Zero emissions
Cons
  • Heavy without batteries
  • Slight lag in wet grass
  • Higher upfront cost

21″ Steel
Acreage
1.5 acres
Runtime
60 Minutes
Charge Time
60 minutes

Step into the future of mowing with the Greenworks Commercial 82V, a battery-powered beast that boldly claims to outmuscle a 160cc gas engine—and largely backs it up. Its high-torque brushless motor generates exceptional cutting power, slicing through dense, tall grass with authority rarely seen in cordless mowers. With a 21” commercial steel deck and 60-minute runtime, it’s engineered for up to 1.5 acres per charge, making it a top pick for large residential or light commercial use.

On test runs across mixed terrain—dry lawns, damp patches, and mixed weeds—the mower maintained consistent blade speed and clean cuts, thanks to its intelligent load-sensing motor. The dual-port charger replenishes the 5.0Ah battery in just 60 minutes, minimizing downtime between jobs. While the single-battery system limits runtime flexibility, the sheer efficiency of the 82V platform compensates by maximizing output per charge. That said, pushing through thick, uncut grass for extended periods does drain the battery faster, and steep inclines can slightly reduce performance.

When stacked against the Makita XML07PT1, the Greenworks delivers more raw power on a single charge, but lacks the modular battery expansion that pros love. It’s also lighter and simpler to operate, making it ideal for landscapers who want gas-level performance without the noise or emissions. For users prioritizing peak cutting strength and fast recharge cycles over battery scalability, this model sets a new benchmark in electric mowing—offering more muscle per volt than any other 21-inch contender.

Pros
  • 82V brushless power
  • 60-min fast charge
  • 1.5-acre capacity
  • Commercial steel deck
  • Quiet operation
Cons
  • Single battery
  • No self-propel
  • Limited runtime expansion

The Greenworks 40V self-propelled mower is a game-changer for homeowners who want professional-grade features without the pro-level price tag. Its brushless motor delivers surprising torque for a 40V platform, offering clean, consistent cuts across medium-sized lawns with minimal user effort. The rear-wheel self-propel system is a standout, providing excellent traction on slopes and damp ground, while the 7-position single-lever height adjustment makes changing cut heights a breeze—no bending or guessing.

In real-world use, the mower handled a quarter- to half-acre lawn on a single 5.0Ah battery, though runtime dipped to 35–40 minutes in thick grass. The vertical storage design saves 70% space, a huge perk for garage or shed owners with tight quarters. While it doesn’t match the raw power of 82V or dual-battery systems, it excels in user comfort and ease of maintenance—starting instantly, running quietly, and requiring zero oil, gas, or emissions checks. It’s not built for daily commercial use, but for weekend warriors and eco-conscious mowers, it’s nearly perfect.

Compared to the Makita or Greenworks 82V models, this mower sacrifices peak power and runtime for affordability and self-propelled convenience. Yet, it outshines budget gas mowers in long-term cost of ownership and ease of use. For those seeking a low-maintenance, self-propelled electric mower that integrates with a growing 40V tool ecosystem, this model offers exceptional value and smart design—making it the most user-friendly entry into serious electric mowing.

Pros
  • Self-propelled
  • Vertical storage
  • Brushless motor
  • 7-position adjust
  • Eco-friendly
Cons
  • Shorter runtime
  • 40V power limit
  • Not for heavy duty

Speed Range
1.5 – 3 MPH
Deck Material
Commercial-grade steel
Run Time
Extended with 4 bay system

Meet the ultimate cordless workhorse for professionals: the Makita XML08Z, a self-propelled titan built for landscapers who demand maximum runtime and zero downtime. With a 4-bay battery system, it supports up to four 18V LXT batteries (36V total), delivering unmatched endurance—easily covering 1+ acres on a single charge cycle. The variable speed self-propel (1.5–3 MPH) adapts to your pace, reducing fatigue during full-day mowing sessions, while the commercial steel deck shrugs off rocks, roots, and daily abuse.

Field tests on uneven, overgrown lawns confirmed its superior traction and cutting consistency, even at top speed. The brushless motor maintains blade RPM under load, though performance dips slightly when all four batteries aren’t fresh. Unlike single-battery systems, the modular power design lets you hot-swap batteries mid-job, a huge advantage for pros managing multiple properties. However, the tool-only package means you must buy batteries separately, which can inflate the total cost—especially if you don’t already own Makita LXT packs.

Against the Greenworks 82V, this mower trades instant peak power for superior runtime flexibility and self-propel convenience. It’s heavier and pricier than most, but for landscaping crews already invested in Makita’s ecosystem, it’s a no-brainer upgrade from gas. If you need a durable, self-propelled electric mower with marathon runtime and pro-grade build, this model delivers the longest continuous operation in its class—making it the top choice for all-day commercial use.

Pros
  • Self-propelled
  • 4-battery support
  • Variable speed
  • Commercial steel deck
  • Hot-swap capable
Cons
  • Tool-only (no batteries)
  • Heavy build
  • High system cost

AMERISUN 21″ Gas Lawn Mower – Best Gas Option

AMERISUN 21
Engine Size
144cc 4-cycle
Deck Size
21″ steel
Mowing Modes
Mulching, side discharge, bagging
Height Adjustments
6 settings (1.5″ to 3.9″)
Wheel Size
7″ front, 10″ rear

For those who trust gas when the job demands reliability, the AMERISUN 21″ push mower delivers no-nonsense power and rugged simplicity. Its 144cc OHV 4-stroke engine with auto choke fires up quickly—no priming or yanking—and sustains steady performance across thick, dry grass and uneven terrain. The 21” high-efficiency steel deck cuts fast and clean, while the 3-in-1 system (bagging, mulching, side discharge) gives you full control over lawn cleanup. It’s a no-frills, ready-to-mow machine that gets the job done without app integrations or charging hassles.

In testing, the mower excelled on overgrown lawns and sloped yards, where electric models often struggle. The 10” rear wheels with dual ball bearings roll smoothly over bumps and curbs, reducing push resistance. The 1.4-bushel grass catcher fills quickly on long jobs, requiring frequent emptying, and the lack of self-propel makes it tiring on larger properties. Still, for users who need unlimited runtime and gas-powered dependability, it’s a solid performer—especially those in rural areas or with spotty electricity access.

Compared to the SENIX LSSG-M9, it offers similar engine size but better wheel design and easier starting, though it lacks self-propel. Against electric models like the Makita or Greenworks, it’s noisier and requires more maintenance, but wins on continuous runtime and raw power. For budget-conscious buyers who want a durable, gas-powered workhorse that starts every time and handles tough mowing days, this mower offers old-school reliability with modern touches—making it the best gas option under $350.

Pros
  • 144cc OHV engine
  • Large rear wheels
  • 3-in-1 mowing
  • Ready to use
  • Foldable design
Cons
  • No self-propel
  • Manual push only
  • Gas maintenance

Cutting Height Adjustment
6-position (1.25-inch to 3.75-inch)
Mower Type

The SENIX LSSG-M9 is a compact powerhouse tailored for small to medium yards where convenience and self-propelled ease matter most. Powered by a Briggs & Stratton 140cc engine, it delivers smooth, vibration-free starts thanks to the Prime N’ Pull ignition system, and maintains consistent power across moderate terrain. The front-wheel self-propel takes the strain out of mowing, while the 6-position dual-lever height adjustment (1.25”–3.75”) lets you fine-tune your cut with precision—ideal for patchy or seasonal lawns.

Real-world use showed strong performance on quarter- to half-acre lawns, with the 16-gallon bagger needing emptying every 15–20 minutes in dense grass. The 11” rear wheels provide excellent maneuverability, making tight turns and slopes manageable, though the mower can feel slightly top-heavy when bagging. It’s not built for heavy commercial use, but for homeowners with uneven lawns or light slopes, it’s a dependable, low-maintenance option—especially with its 2-year warranty adding peace of mind.

Against the AMERISUN model, it offers self-propel and better ergonomics at a slightly higher price, but with a smaller engine and lower cutting deck clearance. Compared to electric models, it lacks instant start and quiet operation, but wins on unlimited runtime and zero charging anxiety. For those with small yards who want gas reliability with self-propelled comfort, the SENIX delivers smooth operation and trusted Briggs & Stratton performance—making it the best choice for effortless, everyday mowing.

Pros
  • Self-propelled
  • Briggs & Stratton engine
  • 16-gallon bagger
  • 2-year warranty
  • Easy start
Cons
  • Smaller engine
  • Top-heavy when full
  • Not for large lawns

How to Choose the Best Commercial Lawn Mower

When selecting a commercial lawn mower, focus on power, runtime, durability, and ease of use to match your specific needs. Below are the key factors to consider:

Power & Performance

Durability & Cutting Features

  • Deck Material: Steel decks (e.g., Makita, Greenworks) resist wear and handle heavy use.
  • 3-in-1 Functionality: Mulching, bagging, and side-discharge options (all listed models) add versatility for different lawn conditions.

Ease of Use

  • Self-Propelled vs. Push: Self-propelled mowers (e.g., Makita XML08Z) reduce fatigue on slopes or large properties.
  • Adjustability: Single-lever height adjustments (e.g., Greenworks 40V) simplify customization.

Other Features:
Storage: Vertical designs (Greenworks 40V) save space.
Wheel Size: Larger wheels (e.g., SENIX’s 11″ rear wheels) improve traction on rough terrain.
Warranty: Check coverage (e.g., SENIX’s 2-year warranty) for long-term reliability.

Choose based on your yard size, terrain, and preference for maintenance (gas vs. electric) to maximize efficiency.

Data-Driven Analysis of Commercial Lawn Mowers

Evaluating the best 21 commercial lawn mower requires moving beyond specifications and leveraging available data. We analyzed performance metrics reported by landscaping professionals and independent review sites, focusing on runtime for electric models and fuel efficiency for gas-powered options. Comparative data reveals Greenworks 82V mowers consistently achieve high user ratings for runtime, capable of covering significant acreage (up to 1.5 acres) per charge – a crucial factor for commercial use.

Research indicates brushless motors, like those found in Makita and Greenworks models, offer superior torque and longevity compared to brushed motors, impacting long-term total cost of ownership. We examined warranty data; SENIX’s 2-year warranty suggests a strong manufacturer confidence in durability. Analyzing user feedback regarding deck material (steel vs. aluminum) shows steel decks, commonly found in Makita and Greenworks mowers, provide increased resilience in demanding professional environments. This research, combined with the factors outlined in our buying guide – power, durability, and ease of use – forms the basis of our recommendations.

FAQs

What size lawn is a commercial lawn mower best suited for?

A commercial lawn mower, like the best 21 commercial lawn mower options discussed, is ideal for lawns ranging from medium to large sizes – typically a half-acre or more – or for professionals maintaining multiple properties. However, even smaller lawns benefit from the durability and power these mowers offer.

What are the main differences between gas and electric commercial mowers?

Gas mowers provide more raw power, suitable for very tough conditions, but require more maintenance. Electric commercial lawn mowers—like those from Makita and Greenworks—offer quieter operation, zero emissions, and lower maintenance, with comparable power for many tasks.
