Unboxing the Ryobi One+ mower is straightforward. The packaging is robust, and everything is well-secured. Here’s the complete inventory you’ll find inside:

• Main Mower Unit: The deck, handle, and wheels are partially assembled. The build quality feels solid, with a metal deck and durable plastic components.
• 45-Liter Grass Collection Bag: This is a semi-rigid tray-style bag with a sturdy handle. It attaches securely to the mower’s rear.
• Mulching Plug/Shutter: A simple plastic insert that blocks the rear discharge chute to enable mulching mode.
• ONE+ 18V 5.0Ah Lithium-Ion Battery: This is the high-capacity battery that provides the claimed runtime.
• ONE+ 18V Fast Charger (2.0A): A standard charger that will replenish the 5.0Ah battery in about 2.5 hours.
• Instruction Manual & Warranty Information: The manuals are clear, with multiple languages and helpful diagrams.

How to Use RYOBI One+ RY18LMX37A-150 Cordless Brushless Lawnmower: Complete Guide

Step 1: Initial Setup and Installation

Assembly is refreshingly simple. Unfold the handle from its shipping position until it clicks into place. You may need to tighten a couple of knobs or levers to secure it. Next, attach the grass collection bag by sliding it onto the mounting brackets at the rear until it clicks. If you wish to mulch, insert the mulching plug into the same chute instead. Insert the fully charged 5.0Ah battery into the compartment on top of the mower. Use the central lever to set your desired cutting height. That’s it—you’re ready to mow.

Step 2: First-Time User Guide

To start, ensure the battery is clicked in securely. There’s no key or complicated ignition. Simply press and hold the safety button on the handle with one hand, then squeeze the start lever with the other. The brushless motor will spin up quietly. Release the lever to stop the blade. It’s intuitive and much safer than a gas mower’s recoil start. Familiarize yourself with the easy height adjuster and the bag-full indicator window on the collection tray.

Step 3: Core Functions and Daily Use

For daily mowing, the process is standard. The push maneuverability is good on flat terrain. The 2-in-1 system is its core function: Use it with the bag attached for a clean, striped-lawn look, or with the mulching plug to return fine clippings to the turf as fertilizer. Switching takes less than a minute. The EasyEdge deflector works as advertised for getting close to fences and garden beds.

Step 4: Advanced Techniques

For the best cut, overlap your passes slightly. If the grass is tall or damp, use the bagging function to prevent clumping. The hot-swap battery compartment is an advanced user’s best friend. Keep a second high-capacity Ryobi 18V battery charged and in the storage slot to instantly double your runtime without walking back to the garage.

Step 5: Maintenance and Care

After each use, tip the mower on its side (with the battery removed) and use a brush or blower to clear grass clippings from under the deck and the air vents. This prevents corrosion and maintains optimal airflow. Periodically check the blade for nicks and sharpness. Wipe down the handle and body with a damp cloth. Store in a dry place. For detailed seasonal care, see our lawn mower maintenance checklist.

Step 6: Troubleshooting Common Issues

Mower won’t start: Check battery charge and connection. Ensure the safety start lever and button are being pressed simultaneously.
Poor cutting performance or uneven cut: Check that the blade is sharp and not bent. Ensure all wheels are set to the same height via the central adjuster.
Bag not filling: The chute or deck underside may be clogged with wet grass. Clean thoroughly. Ensure the mulching plug is not installed if you intend to bag.

Following this guide will ensure you get the most out of your decision to buy ryobi one+ 18v lawn mower.

Performance & Real-World Testing

Testing Methodology

We used the mower over three weeks on a 350 square meter lawn with a mix of Kentucky bluegrass and fescue. Testing conditions included dry, short grass; damp, morning grass; and one session with overgrown turf to simulate a missed weekend. We measured runtime, cutting quality, noise levels, and ease of use.

Performance Metrics

The brushless motor provides consistent power. In dry, standard-height grass, the cut was clean and even, rivaling a gas mower. The 45L bag filled up at expected intervals and was easy to detach and empty. Noise was significantly lower than a gas mower, allowing for conversation at normal volume—a major neighborhood-friendly benefit.

Real-World Scenarios

On damp grass, performance was good, though the underside required more frequent cleaning to prevent clumping. In the overgrown test, the mower handled it but demanded a slower pace and immediately filled the bag. This confirmed it’s best for regular maintenance, not reclaiming a jungle. The battery life was accurate: the 5.0Ah battery consistently delivered 35-40 minutes of runtime, enough for the advertised 300-400 m² lawn if you keep up with mowing.

Claims vs. Reality

Ryobi’s claims largely held up. The brushless motor is powerful and efficient. The battery runtime is realistic for the target lawn size. The EasyEdge feature is helpful but won’t replace a dedicated trimmer for tight spots. The central height adjustment is as convenient as promised. The core question of ryobi one+ lawn mower worth it is affirmed for its intended use case.

Pros and Cons

What We Loved (Pros)

• Silent, Fume-Free Operation: No noise pollution, no gas smells, and instant start every time.
• ONE+ Battery Ecosystem: Massive value if you own other Ryobi tools. One battery for everything.
• Excellent Cutting Quality: The brushless motor and sharp blade deliver a clean, even cut in normal conditions.
• Superior Convenience Features: Central height adjust, easy bag attachment, and secondary battery slot are well-executed.
• Low Maintenance: No oil, spark plugs, or air filters to deal with ever again.

What Could Be Improved (Cons)

• Push-Only on Slopes: With no self-propelled option, it can be a workout on hilly terrain.
• Battery Runtime for Large/Overgrown Lawns: While sufficient for its rated area, you’ll need a spare battery for anything larger or if the grass is very thick.
• Plastic Components: Some parts, like the bag, feel durable but are still plastic. Long-term ruggedness compared to all-metal commercial mowers is untested.

RYOBI One+ RY18LMX37A-150 vs. Competitors

The main competitors in the cordless space are EGO and Milwaukee. Here’s a quick comparison:

Feature	Ryobi One+ RY18LMX37A-150	EGO LM2102SP (56V)	Milwaukee M18 (18V)
Battery Voltage/Platform	18V ONE+ (Shared)	56V (Dedicated)	18V M18 (Shared)
Cutting Width	37cm (14.5″)	53cm (21″)	43cm (17″)
Self-Propelled	No	Yes	No
Typical Price Point	$$ (Mid-Range)	$$$ (Premium)	$$$ (Premium)
Ideal User	Ryobi ecosystem owner with a small/medium flat lawn.	Owner of a larger or sloped lawn wanting premium power & features.	Milwaukee M18 tool user needing a capable cordless mower.

When to Choose This Product

Choose this Ryobi if you already have Ryobi 18V tools, have a flat or gently sloped lawn under 400m², and value ecosystem convenience over maximum power. It’s the definition of a smart, integrated tool for the suburban homeowner.

When to Consider Alternatives

Consider an EGO if your lawn is large (over 500m²) or hilly, and you need self-propelled assistance and maximum runtime per charge. The ryobi vs ego lawn mower debate often ends with EGO for raw power, but Ryobi for system value. Consider Milwaukee if you’re already invested in their professional-grade M18 platform.

Who Should Buy RYOBI One+ RY18LMX37A-150?

Ideal For:

• Existing Ryobi ONE+ Tool Owners: This is a no-brainer addition. Leverage your existing batteries and charger.
• Urban/Suburban Homeowners with Small-Medium Lawns: If your yard is under 400m² and relatively flat, this mower is perfectly sized.
• Those Seeking Low-Maintenance & Quiet Operation: Perfect for anyone tired of gas engine upkeep and noise.

Not Recommended For:

• Owners of Large or Very Hilly Lawns: The lack of self-propulsion and battery limitations will be frustrating.
• Those Needing Commercial-Grade Durability: This is a homeowner-grade tool, not for daily commercial use.
• Anyone Without Any Ryobi Batteries: While it comes with one, the value is maximized within the ecosystem. If you own no batteries, compare total system costs.

Expert Tips for Maximum Value

Tip #1: Keep the Blade Sharp

A sharp blade is the single biggest factor in cutting quality and battery efficiency. A dull blade tears grass, leading to brown tips and requiring more power from the motor.

Tip #2: Mow When Dry

Always mow dry grass if possible. Wet grass clumps, clogs the deck, weighs down the bag, and drastically reduces effective battery runtime.

Tip #3: Invest in a Spare High-Capacity Battery

For peace of mind and to handle edge cases, buy a spare 6.0Ah or 9.0Ah Ryobi ONE+ battery. Use the storage compartment to keep it on the mower.

Tip #4: Use the Mulching Plug for Healthier Lawns

For regular mowing, use the mulching plug. The fine clippings decompose quickly, returning nitrogen and moisture to the soil, reducing fertilizer needs.

Tip #5: Clean the Deck After Every Use

Taking two minutes to brush off clippings prevents rust, maintains balance, and ensures proper airflow for cooling the motor.

Tip #6: Register for the Extended Warranty

Don’t forget to register your mower online within 30 days of purchase to activate the third year of warranty coverage—it’s free extra protection.

Common Mistakes to Avoid

1. Mistake: Letting the grass get too long between mows. → Solution: Stick to a regular schedule, never cutting more than 1/3 of the grass blade height at once.
2. Mistake: Mowing in wet conditions. → Solution: Wait for the dew to dry or for a sunny day after rain.
3. Mistake: Storing the mower with a dead battery. → Solution: Store the lithium-ion battery at around 50% charge in a cool, dry place.
4. Mistake: Using the wrong cutting height (too short). → Solution: For most grasses, keep the cutting height between 50-70mm (2-3 inches) to promote deep roots and crowd out weeds.
5. Mistake: Forgetting to check the bag fullness indicator. → Solution: Glance at the indicator window periodically. An overfull bag reduces suction and cutting efficiency.

Pricing & Where to Buy

The RYOBI One+ RY18LMX37A-150 has a current price of around $829.98.

It represents strong value within the Ryobi ecosystem. The best place to purchase is through authorized retailers to ensure you get a genuine product, full warranty, and reliable customer service.

Warranty & Support

Spare parts are guaranteed to be available for at least 5 years, which is a reassuring commitment for longevity.

Frequently Asked Questions

Is RYOBI One+ RY18LMX37A-150 Cordless Brushless Lawnmower worth the money?

Yes, especially if you are already invested in the Ryobi ONE+ 18V platform. The upfront cost includes a high-capacity battery and charger you can use across many tools. When evaluated as part of a system and against long-term gas and maintenance costs, it offers excellent value for homeowners with small to medium, flat lawns.

How does it compare to EGO mowers?

The ryobi vs ego lawn mower comparison often comes down to power vs. ecosystem. EGO’s 56V mowers generally offer more power, wider decks, and often self-propelled options, making them better for larger or tougher lawns. Ryobi wins on value and convenience if you already own their 18V batteries, offering capable performance for smaller yards at a typically lower entry price.

What’s the learning curve for beginners?

Virtually zero. If you’ve used a push mower before, you can use this. The assembly is minimal, it starts with a trigger squeeze (no pull cord), and the controls are intuitive. It’s arguably easier for a beginner than a gas mower due to the lack of complex starting procedures.

What accessories or additional items do I need?

The mower comes complete. The only essential accessory you might want immediately is a spare high-capacity battery (6.0Ah or 9.0Ah) for larger lawns. A blade sharpening kit is a good long-term investment. A leaf blower from the same ONE+ line is perfect for cleaning the mower deck and your driveway afterward.

What warranty and customer support does it offer?

Ryobi offers a 3-year warranty (2 years standard + 1 year extended upon registration). This covers both the tool and the battery against defects in materials and workmanship. Customer support is available through their website and phone lines, with a network of authorized service centers.

Where can I buy it at the best price?

We recommend purchasing from this authorized retailer for competitive pricing, authentic products, and reliable shipping. Always check for bundle deals that might include an extra battery or other tools.

Can it handle slightly wet or dewy grass?

It can handle light dew or slightly damp grass, but performance will suffer. The deck is more likely to clog, the bag will get heavy quickly, and battery life will be reduced. It’s always best to mow when the grass is completely dry for optimal results.

Is the battery interchangeable with all Ryobi 18V tools?

Yes, absolutely. This is the core of the ONE+ system. The included 5.0Ah battery (and any other ONE+ 18V battery) will work in every tool bearing the ONE+ logo, from drills and saws to leaf blowers and inflators.
