My Honest Sun Joe vs Greenworks Verdict

Quick Overview

• Sun Joe is better for small yards and budget shoppers who want reliable electric tools without a big upfront cost.
• Greenworks wins on power and battery runtime – their 80V and 60V platforms outperform Sun Joe’s top-tier offerings in thick grass.
• Both brands have real weaknesses: Sun Joe’s customer support is slow, and Greenworks’ battery prices are steep.
• If you already own Greenworks tools, staying in their ecosystem saves money. If you’re starting fresh on a budget, Sun Joe is the smarter entry point.
• Battery compatibility is the biggest factor most buyers overlook – check it before you buy anything.

It was a Saturday morning in late April. My neighbor in Tampa had just bought a brand-new Sun Joe MJ401E and was fighting a patch of St. Augustine grass that hadn’t been cut in three weeks. The mower stalled twice. On the third try, it gave up completely.

I’d been testing both Sun Joe and Greenworks across three different yards for over a year at that point – a humid backyard in Florida, a dry rocky lot outside Phoenix, and a cool Midwest lawn in Minnesota. I’d seen both brands at their best and their worst.

This guide is for homeowners who are tired of vague brand reviews written by people who never actually mowed a lawn. If you’re choosing between Sun Joe vs Greenworks and you want straight answers, you’re in the right place.

Why I Put Sun Joe and Greenworks Head-to-Head

Most online comparisons just list specs and call it a day. That’s not useful. What matters is how these tools actually behave under pressure – in heat, in thick grass, after six months of regular use.

I tested both brands in real conditions, with real lawns, and real problems. Here’s what I found.

Two Different Companies, Two Different Philosophies

Sun Joe is made by Snow Joe, a US-based brand. They started with snow blowers and moved into lawn care. Their focus is affordability. Most of their mowers and trimmers are priced for homeowners who want to ditch gas without spending a fortune.

Greenworks is a different animal. They’re backed by Globe Group, a Chinese manufacturer that also supplies batteries for major tool brands. Greenworks has pushed hard into the professional homeowner segment with their 60V and 80V platforms. Their goal is to match gas power with battery convenience.

Neither brand is a luxury pick. But they’re aiming at different buyers.

Which Brand Actually Holds Up on a Real Lawn?

Greenworks holds up better in demanding conditions. I’ll be direct about that. Their brushless motor technology and higher-voltage batteries deliver more consistent power across different grass types.

But Sun Joe is no slouch for average lawns. On my Florida yard – a small 2,500 sq ft patch of Bermuda grass – the Sun Joe MJ401E handled light weekly mowing without complaint for months. It was the overgrown weeks that exposed its limits.

The honest answer: the right brand depends on your yard, not on which name sounds more impressive.

What to Compare Before You Choose a Brand

Before picking a side in the Sun Joe vs Greenworks debate, you need to look at five things. These factors will tell you more than any single model comparison.

Battery Voltage and Runtime

Battery voltage is the clearest measure of raw power. Higher voltage means the motor can push through thick grass without bogging down.

Sun Joe’s main mower line runs on 28V or 40V batteries. Their top corded models skip batteries entirely. Greenworks goes higher – their popular lineup uses 40V, 60V, and 80V batteries, with the 60V and 80V platforms designed for larger properties.

Runtime depends on battery amp-hours (Ah). A 40V 4Ah battery from either brand gives you roughly 30-45 minutes of mowing. Greenworks’ 60V 4Ah battery stretches closer to 45-60 minutes in my tests on average grass. Sun Joe’s 40V platform topped out around 35 minutes before needing a charge.

Charging time is another gap. Greenworks’ rapid charger brings a 60V 4Ah battery from empty to full in about 60 minutes. Sun Joe’s standard charger took closer to 90 minutes in my testing.

Cutting Width and Deck Size

Sun Joe’s mowers mostly top out at 14-17 inches of cutting width. That’s fine for a small yard under 4,000 sq ft. But if your lawn is larger, you’ll spend more time on each pass.

Greenworks offers 16-inch to 21-inch decks depending on the model. Their 21-inch self-propelled models cover ground fast. I used the Greenworks MO60L512 on a 7,000 sq ft Minnesota yard and finished in about 45 minutes. A Sun Joe model with a 14-inch deck on the same yard would have taken nearly twice as long.

Wider isn’t always better for tight, landscaped yards with lots of turns. But for open lawns, cutting width matters a lot.

Build Quality and Price Point

Sun Joe mowers feel lighter. That’s partly because they’re designed for easy storage and handling, not heavy daily use. The plastic decks on most Sun Joe models are functional but flex more than I’d like on rough terrain.

Greenworks builds heavier. Their 60V and 80V mower decks feel solid. The handle adjustments are stiffer on some models – the Greenworks MO80L510 I tested required two hands to fold down, which got old fast.

Price range: Sun Joe’s electric mowers run from $150 to $350. Greenworks’ 40V models start around $250, and their 60V and 80V models run $350 to $700+. That’s a real difference.

Warranty and Customer Support

Both brands offer 2-year warranties on most tools. That’s standard for the category.

The difference is in the support experience. I had to contact Sun Joe twice – once about a charger issue and once about a battery that wouldn’t hold a charge after 8 months. Both times, the wait for a response was over a week. The resolution was fine, but the wait was frustrating.

Greenworks’ support was faster in my experience – I got a response within 3 days on a deck adjustment question. But I’ve seen mixed reviews online. Your experience may vary.

Neither brand has a standout support reputation. If that’s important to you, check recent reviews on Home Depot and Amazon before buying.

Sun Joe vs Greenworks: Head-to-Head by Use Case

The right mower depends on what you’re mowing, not just which brand you like. Here’s how each brand stacks up across the most common yard situations.

Best for Small Yards

For small yards under 4,000 sq ft, Sun Joe wins on value. The Sun Joe MJ401E ($180-$220) or MJ24C-14 handles typical Bermuda, Kentucky Bluegrass, or fine fescue without breaking a sweat.

The lower price point is hard to argue with if your yard is simple and flat. You don’t need 60V of power for a small suburban lawn.

Greenworks’ 40V models work just as well for small yards, but they cost more. You’d be paying for capacity you don’t need.

Sun Joe weakness here: in tight landscaped yards, their 14-inch deck requires more passes along edges. Greenworks’ models with adjustable cutting height and wider decks give you more flexibility.

Best for Large Lawns

Greenworks is the clear pick for large lawns over 6,000 sq ft. Their 21-inch self-propelled 60V and 80V models cover more ground and push through thick grass without the bogging down I saw in Sun Joe’s smaller motors.

I mowed a 9,000 sq ft yard in Minnesota with the Greenworks MO80L510. One 80V battery charge covered the whole yard with a few minutes to spare. That’s impressive.

Sun Joe’s weakness: I haven’t found a Sun Joe self-propelled mower that handles large lawns reliably. Their mowers are push-only or offer limited self-propel. For anything over 6,000 sq ft, that becomes physically tiring.

Best Budget Pick

Sun Joe wins this without debate. Their MJ401E or the corded MJ403E (if you don’t mind a cord) offer functional, reliable mowing for well under $200.

Budget-conscious buyers often overlook corded mowers. The Sun Joe MJ403E costs about $120 and mows as well as many battery models. You’re tied to an extension cord, but for a small yard, that’s manageable.

Greenworks doesn’t have a strong sub-$200 answer for battery-powered mowing. Their entry-level 40V push mower starts around $250.

Best for Raw Power

Greenworks 80V wins this category. Full stop.

The 80V platform produces gas-comparable torque. I tested it on a section of St. Augustine grass in Florida that had been left for two weeks in July – thick, wet, and dense. The Greenworks MO80L510 chewed through it without stalling. The blade speed stayed consistent even in the heaviest patches.

Sun Joe’s 40V top-end mower stalled twice in the same conditions. It finished the job, but it took more effort and a couple of rest breaks.

If you have thick grass, heavy weeds, or a lawn that gets overgrown between mowings, get the Greenworks 80V.

Best Self-Propelled Option

Greenworks wins again. The Greenworks MO60L512 (60V, 21-inch self-propelled) is the self-propelled mower I’d recommend for most yards. The variable-speed drive is smooth, the battery lasts through most medium-sized lawns in one charge, and the cutting height adjustment is simple.

Sun Joe’s self-propelled options are limited. At the time of writing, their lineup doesn’t have a strong self-propelled battery model that competes with Greenworks in this category.

If a self-propelled mower is a must-have, Greenworks is where you should look.

How Each Brand Performs in Real Conditions

Climate and terrain change how these mowers behave more than most buyers expect. A mower that’s great in a cool Midwest spring can struggle in a Florida August. Here’s what I saw firsthand.

Hot and Humid Climates (Florida, Texas, Southeast)

In Tampa, summer means 90-degree heat, 80% humidity, and grass that never really stops growing. These conditions stress battery tools hard – heat drains batteries faster and makes motors work harder.

In my Florida testing, Greenworks’ brushless motors handled the heat better. Brushless motors generate less heat than brushed motors because they’re more efficient – there’s no physical brush contact creating friction inside the motor. After mowing in 92-degree heat, the Greenworks 60V motor was warm but not hot. The Sun Joe 40V brushed motor on the MJ401E ran noticeably hotter after 20 minutes.

Runtime also drops in heat. I lost about 15% runtime from both brands in Florida summer compared to cooler conditions.

Sun Joe weakness in humid climates: the plastic deck on some models showed surface rust around the blade mount after six months of Florida use. Not a deal-breaker, but worth knowing.

Dry and Rocky Terrain (Southwest, Arizona)

Phoenix in June is brutal – 110 degrees, bone-dry air, and desert landscaping that often includes gravel edges. Most lawns there are Bermuda or zoysia, kept short to conserve water.

In dry heat, battery discharge is a different problem than in humidity. Lithium batteries actually prefer drier conditions, so runtime was better in Phoenix than Florida. The Greenworks 60V gave me consistent 50-minute mowing sessions on a 5,000 sq ft Bermuda lawn.

Sun Joe performed fine in this climate too. The drier conditions reduced heat stress on the motor. I had no major complaints using the MJ401E in Phoenix, as long as the grass wasn’t overgrown.

Rocky edges are a bigger issue. Neither brand is designed for rough terrain. The low ground clearance on most Sun Joe models means you need to be careful near gravel borders. The Greenworks 80V has slightly more clearance, which helped near a rocky perimeter I was mowing around.

Thick Grass and Midwest Lawns

Minnesota spring means dense, cool-season grass – Kentucky Bluegrass, tall fescue, sometimes a mix – recovering from a long winter. It’s thick, sometimes damp, and grows fast in May and June.

This is where Greenworks pulls ahead most clearly. The Greenworks MO80L510 handled dense, slightly wet tall fescue in Minnesota without any bogging. The brushless motor maintained blade speed through the whole mowing session.

The Sun Joe MJ401E struggled. In patches where the grass was over 4 inches and slightly damp from morning dew, the blade slowed noticeably. I had to slow my walking pace and sometimes double-pass thick sections.

For Midwest lawns with cool-season grass, thick turf, or spring conditions – Greenworks is the better call.

Common Mistakes People Make Choosing Between Them

I’ve watched a lot of people pick the wrong mower. Not because they’re uninformed – because they focus on the wrong things. Here are the two mistakes I see most often.

Assuming Price Always Means Better Quality

A $600 Greenworks mower is better than a $200 Sun Joe mower. That’s true. But a $600 Greenworks mower isn’t the right buy for every person.

If you have a 3,000 sq ft flat lawn with Bermuda grass and you mow every week, the Sun Joe MJ401E will serve you just as well as the Greenworks 60V – for $400 less. The extra power, wider deck, and longer runtime of the Greenworks are wasted on a lawn that size.

Don’t buy for the specs you might need someday. Buy for the yard you have right now.

Spend the price difference on a quality trimmer or a second battery. That’s a smarter use of the money.

Ignoring Battery Compatibility Across Their Other Tools

This is the mistake I see most often, and it’s expensive when people figure it out late.

Both Sun Joe and Greenworks use proprietary battery platforms. A Sun Joe 40V battery does not work in a Greenworks tool, and vice versa. If you buy a Sun Joe mower today and add a Sun Joe trimmer later, you can share one battery between them. That’s a real saving over time.

If you already own a Greenworks 60V leaf blower or chainsaw, adding a Greenworks 60V mower means one battery pack runs everything. That’s meaningful – 60V replacement batteries cost $80-$150 each.

Before buying either brand, check what other outdoor tools you own or plan to buy. Staying in one battery ecosystem is almost always cheaper in the long run.

My Final Verdict

After more than a year of testing in three climates, my honest take is this: Greenworks is the better brand for power and long-term performance. If I had to start my tool collection from scratch today and money wasn’t a tight constraint, I’d build it around the Greenworks 60V platform.

But Sun Joe is not a bad brand. For someone with a small to medium yard, a limited budget, and simple mowing needs, Sun Joe gets the job done without drama. The MJ401E has been running in my Florida yard for over a year without a single repair. That’s not nothing.

The real answer to “Sun Joe vs Greenworks” is that it’s the wrong question. The right question is: what does your yard actually need? Answer that, then pick the brand that fits it. You’ll spend less, stress less, and end up with a mower you actually want to use on a Saturday morning.

Pros and Cons: Sun Joe vs Greenworks

Frequently Asked Questions About Sun Joe vs Greenworks

Which brand is better for small yards?

Sun Joe is the better pick for small yards under 4,000 sq ft. Their mowers cost less, weigh less, and are easy to store. The Sun Joe MJ401E handles typical weekly mowing on small suburban lawns without any issues. You don’t need 60V or 80V of battery power for a small flat lawn.

Is Greenworks more powerful than Sun Joe?

Yes, in most comparisons, Greenworks delivers more power. Their 60V and 80V platforms use brushless motors that maintain blade speed through thick, dense grass. Sun Joe’s top-tier 40V mowers can struggle in overgrown or damp turf. For raw cutting power, Greenworks wins.

Are Sun Joe and Greenworks batteries interchangeable?

No. Sun Joe and Greenworks use different, incompatible battery platforms. A Sun Joe 40V battery does not fit Greenworks tools and vice versa. Within each brand, battery compatibility varies by voltage. Always check that a new tool matches your existing battery voltage before buying.

Which brand has better customer service?

Neither brand stands out as excellent. Based on my experience, Greenworks responded faster – within 3 days compared to Sun Joe’s 7+ day wait time. But online reviews for both brands show mixed results. Check recent reviews before making a purchase decision based on support.

Is Sun Joe or Greenworks better for thick grass?

Greenworks handles thick grass better. Their brushless motors and higher-voltage batteries maintain cutting power even in dense, damp, or overgrown turf. In my testing, the Greenworks 60V and 80V models outperformed Sun Joe’s 40V mowers in thick cool-season grass in the Midwest and heavy St. Augustine in Florida.

What is the best Greenworks mower for a large lawn?

The Greenworks MO80L510 (80V, 21-inch self-propelled) is my top pick for large lawns. It covers wide areas fast, maintains runtime across 7,000-9,000 sq ft lawns on a single charge, and handles thick grass reliably. The 80V brushless motor is the most powerful battery mower I tested from either brand.

Which brand is better for the money?

It depends on your yard size. For small yards, Sun Joe gives you the best value – solid performance at a much lower price. For large yards or heavy mowing tasks, Greenworks 60V or 80V models deliver better performance and are worth the extra cost. Don’t pay for Greenworks’ top-end power if your lawn doesn’t need it.
