Best Ryobi Lawn Mower: Which One Will Transform Your Lawn Care?

Your old gas mower finally quit. Or maybe you’re tired of hauling extension cords across the yard. Either way, you’re staring at a lineup of Ryobi mowers and wondering which one actually fits your lawn.

A great cordless mower balances three things: cutting width, battery platform, and weight. Too wide, and you can’t maneuver around flower beds. Too narrow, and mowing takes forever. And the battery system matters more than most people realize, because it locks you into a whole ecosystem of tools.

We looked at five mowers that cover very different jobs. The Ryobi 40V push mower is the all-rounder for most suburban yards. The 18V OLM1833B is the budget pick if you already own Ryobi batteries. Worx offers two strong alternatives, including a 40V model built for half-acre lots. And the Ryobi 3-in-1 trimmer handles the edges your mower can’t reach.

Here’s a quick spec comparison to help you see the differences at a glance.

Ryobi Cordless Push Lawn Mower 40V

The one you buy when you want a quiet, no-fuss mower for a typical suburban yard.

This is Ryobi’s 20-inch, 40-volt push mower. It’s aimed at homeowners with quarter-acre to third-acre lots who want to ditch gas without spending a fortune. The 40V platform gives it enough muscle to handle regular weekly cuts on Bermuda, fescue, or bluegrass.

What sets it apart is the noise level. Ryobi built this with a whisper-quiet design, so you can mow early on a Saturday without waking the neighbors. The 20-inch deck hits a sweet spot too. It’s wide enough to finish a standard front yard in 30 to 40 minutes, but narrow enough to navigate around trees and garden beds without three-point turns.

The trade-off? It ships as a bare tool in some listings, so check whether a battery and charger are included before you buy. And the push design means you’re doing all the work on slopes. If your yard has steep hills, a self-propelled model would serve you better.

• 20-inch cutting deck for efficient coverage
• 40V battery system delivers gas-like power
• Whisper-quiet operation for early morning mowing
• Push design keeps the mower lightweight
• Compatible with other Ryobi 40V tools

Best for: Homeowners with flat or gently sloped quarter-acre lots who want a quiet, reliable cordless mower.

RYOBI OLM1833B Cordless Lawnmower

The smart pick if you already own Ryobi 18V ONE+ batteries and have a small yard.

Ryobi designed this mower for people already invested in the 18V ONE+ system. It runs on the same batteries as your drill, trimmer, and blower. That’s a big deal if you own several Ryobi tools, because you skip the cost of a new battery platform entirely.

The 33 cm cutting width makes it best for small lawns under a quarter acre. Five height settings from 25 to 65 mm give you decent control across seasons. The EasyEdge grass combs let you mow right up against fences and walls, which cuts down on trimming time. And the handle folds for storage, which matters if your garage is already crowded.

Here’s the honest catch: this mower ships without a battery or charger. If you don’t already own 18V ONE+ batteries, you’ll need to factor that into your total cost. Also, the 33 cm deck means more passes on anything larger than a postage stamp lawn.

• Runs on Ryobi 18V ONE+ batteries you may already own
• 33 cm cutting width suits small yards
• 5-stage height adjustment from 25 to 65 mm
• EasyEdge combs for close-to-edge mowing
• Foldable handle for compact storage

Best for: Ryobi 18V ONE+ owners with small lawns who want a bare-tool mower at a lower upfront cost.

Worx Cordless Lawn Mower WG733.1

The compact problem-solver for tight yards and narrow gate access.

Worx built this 14-inch mower for people with small, cluttered yards. It’s a 20V machine with a brushless motor, which means longer runtime and less maintenance than brushed motors. The compact frame slips through narrow gates and around tight landscaping features.

Two features stand out. First, the cut-to-edge design lets you trim right along fences and flower beds without a separate string trimmer pass. Second, the single-lever height adjustment switches between six positions from 1 to 3 inches. That’s more height options than most mowers in this size class. The 2-in-1 bag and mulch function covers the basics without overcomplicating things.

Downside: a 14-inch deck means more passes on anything beyond a small yard. And the 20V battery won’t match the runtime of a 40V system on thicker grass. It’s a niche tool, but for the right yard it’s hard to beat.

• 14-inch deck fits through narrow gates
• Brushless motor for longer runtime
• 6-position single-lever height adjustment (1-3 in)
• Cut-to-edge design reduces trimming
• 2-in-1 bagging and mulching

Best for: Homeowners with small, obstacle-heavy yards who need a maneuverable mower that fits tight spaces.

Worx Cordless Lawn Mower WG752

The one that handles half an acre without breaking a sweat.

This is Worx’s answer to larger lawns. The WG752 runs on two 20V 5.0Ah PowerShare Pro batteries that combine for 40V of power. It’s rated for lawns up to half an acre. The 21-inch deck covers ground faster than any other mower on this list.

Two technologies make it stand out. AeroDeck uses a vented cutting deck to boost airflow, which prevents clogs and improves bag collection. IntelliCut sensors automatically ramp up cutting speed in thick grass and dial it back in thin areas to save battery. The brushless motor 2.0 delivers 40% more power and 10% longer runtime than the first-gen version. And the 3-in-1 design lets you mulch, bag, or side-discharge depending on conditions.

The main trade-off is availability. This model is often scarce, so check stock before you get your hopes up. It’s also heavier than the smaller mowers here, which matters if you’re pushing uphill.

• 21-inch deck for fast coverage on large lawns
• Runs on two 20V PowerShare Pro batteries
• AeroDeck technology reduces clogs and improves bagging
• IntelliCut sensors adjust speed based on grass thickness
• 3-in-1 mulching, bagging, and side discharge

Best for: Homeowners with up to half an acre who want a powerful, smart cordless mower with long runtime.

RYOBI 3-in-1 18V Lawn Mower/Edger

The finishing tool that handles everything your mower can’t reach.

This isn’t a replacement for a push mower. It’s a 3-in-1 trimmer, edger, and mini-mower for small lawn maintenance. Ryobi designed it for bed borders, slope edges, and tight spots where a full-size mower won’t fit. It runs on the 18V ONE+ battery system, so it fits right into your existing Ryobi collection.

The 30 cm cutting width and 4-position central height adjustment (43-88 mm) make it surprisingly capable for light mowing. The ergonomic foot control lets you switch between trimmer and edger mode without bending down. A telescopic tube and adjustable front handle accommodate different heights and postures. The 3-position tilting cutting head reaches under bushes and along walls.

Battery life is the real limitation. Runtime ranges from 8 minutes on a 2.0Ah battery to 25 minutes on a 6.0Ah pack. That’s fine for edging and touch-ups, but not for mowing a whole lawn. It’s a companion tool, not a standalone solution.

• 3-in-1 trimmer, edger, and mini-mower
• 30 cm cutting width for tight areas
• 4-position height adjustment (43-88 mm)
• Foot-controlled mode switching
• Runtime varies from 8 to 25 minutes depending on battery

Best for: Ryobi 18V ONE+ owners who need a dedicated tool for edging, borders, and hard-to-reach spots.

How We Chose These Products

We focused on mowers that solve specific problems rather than trying to be everything to everyone. Cutting width, battery compatibility, and weight were the first filters. A mower that’s too wide for your gate or too heavy for your slope doesn’t help, no matter how good the specs look on paper.

We also weighed the battery ecosystem heavily. Ryobi and Worx both have large platforms, so your investment carries over to other tools. The mowers that ship without batteries got extra scrutiny, because the total cost changes depending on what you already own. For more options beyond this shortlist, this detailed Ryobi mower roundup covers additional models worth considering.

Buying Guide: What Really Matters

Deck size is the first decision. A 14-inch mower works for tiny yards with lots of obstacles. A 20 or 21-inch deck cuts mowing time significantly on open lawns. Match the deck to your yard’s layout, not just its square footage.

Battery voltage matters less than battery platform. A 40V mower has more power than an 18V or 20V model, but if you already own a stack of 18V batteries, the lower voltage might still be the smarter buy. The best mower is the one that doesn’t force you to start a new battery collection from scratch.

Think about weight and maneuverability too. Push mowers are lighter but require more effort on slopes. Self-propelled models cost more and weigh more, but save your back on hills. And check whether the mower includes a battery. Bare-tool listings look cheaper until you add the cost of a battery and charger. For a deeper comparison of 40V versus 18V systems, this breakdown of Ryobi’s voltage platforms is worth a read.

Our Top Recommendation

The Ryobi 40V 20-inch push mower is the best all-around choice for most homeowners. It hits the sweet spot between power, cutting width, and quiet operation. The 40V system gives it enough muscle for regular weekly cuts, and the 20-inch deck keeps mowing time reasonable without making the mower unwieldy.

If you already own Ryobi 18V ONE+ batteries and have a small yard, the OLM1833B is the smarter buy. You skip the battery cost entirely and get a capable mower for small lawns. For larger properties up to half an acre, the Worx WG752 is the strongest performer on this list, assuming you can find it in stock. And if edging and borders are your main pain point, the Ryobi 3-in-1 trimmer fills a gap no mower can cover.

Frequently Asked Questions

Can I use a Ryobi 18V battery in a 40V mower?

No. Ryobi’s 18V ONE+ and 40V systems use different batteries and aren’t cross-compatible. You’ll need to pick one platform and stick with it, or buy adapters, which Ryobi doesn’t officially recommend.

How long does a cordless mower battery last on one charge?

It depends on the voltage, battery capacity, and grass conditions. A 40V mower with a 5.0Ah battery typically runs 30 to 45 minutes on a moderate lawn. Thick, wet grass drains batteries faster.

Is a 14-inch mower too small for a quarter-acre yard?

Probably. A 14-inch deck is best for small yards under an eighth of an acre. On a quarter acre, you’ll make a lot of passes. A 20-inch deck would cut your mowing time roughly in half.

Do I need a self-propelled mower for a sloped yard?

If your slope is steep or you have back issues, yes. Push mowers work fine on flat ground and gentle slopes. But on anything steeper than about 15 degrees, a self-propelled model saves significant effort.
