Ryobi 20″ RY40190 40-Volt Brushless Lithium-Ion Cordless Battery Self Propelled Lawn Mower
I found the Ryobi RY40190 to be a remarkably quiet operator that takes the physical strain out of backyard maintenance. This unit features a brushless motor that automatically adjusts its power output based on the thickness of your grass, which helps preserve your battery charge. The rear-wheel drive system provides consistent uphill assist without requiring you to muscle the machine around corners. The package arrives brand new in its original box, complete with a 5.0 Ah 40-Volt battery and a dedicated charger. I particularly appreciate the telescoping handle design because it allows you to fold the entire machine flat for vertical storage in a crowded garage.

- Rear-Wheel Self-Propelled Drive: Maximizes traction on slopes and reduces pushing effort on uneven terrain.
- Single-Point Height Adjustment: Allows you to change the cutting height of all four wheels simultaneously with one simple lever.
- 2-in-1 Mulching and Bagging: Easily switch between recycling nutrients back into your lawn or collecting clippings.
- Vertical Storage Capability: Fold-flat handles reduce the mower footprint by up to seventy percent in your shed.
Pros
- Whisper-quiet operation does not disturb your neighbors during early morning cuts.
- No gas, oil, spark plugs, or winterization maintenance required.
- Lightweight plastic deck makes the machine highly maneuverable around tight flowerbeds.
- Battery is fully compatible with over eighty other Ryobi 40V garden tools.
Cons
- Plastic deck feels less durable than traditional steel alternatives when hitting stray rocks.
- Wet or overly tall grass can deplete the single 5.0 Ah battery faster than expected.
- Battery recharge time can halt your progress mid-job if you have a larger yard.
Best for: Homeowners with quarter-acre suburban lots who want a quiet, zero-maintenance mowing experience without dealing with fuel cans.
Expert Opinion: The Ryobi RY40190 excels at delivering hassle-free, push-button starts every single time, making it the perfect replacement for finicky small gas engines on manicured lawns.
PowerSmart 21″ Self-Propelled Gas Lawn Mower
The PowerSmart gas mower is a traditional workhorse designed for those who value raw cutting power and runtime endurance above all else. This machine centers around a 170cc OHV gas engine that tears through dense, overgrown weeds without bogging down. The heavy-duty 21-inch steel deck provides a wide cutting path that significantly reduces the number of passes you need to make on larger lawns. With its 3-in-1 capability, you can bag, mulch, or use the side discharge chute depending on your lawn care strategy. The combination of 10-inch rear wheels and rear-wheel drive makes navigating bumpy, sloping terrain feel almost effortless.
- 170cc OHV Gas Engine: Provides high torque and consistent cutting power to handle tall, wet, or thick grass varieties.
- 21-Inch Steel Deck: Offers a wide cutting path for faster completion times and superior long-term durability.
- 3-in-1 Grass Management: Includes options for rear bagging, mulching, and side discharge straight out of the box.
- 6-Position Height Adjustment: Dual levers allow you to easily customize your cutting height from 1.5 to 3.9 inches.
- 10-Inch High Rear Wheels: Large rear tires improve stability, traction, and maneuverability over rough ground.
Pros
- Unmatched cutting torque tackles thick weeds and damp grass without stalling.
- Unlimited runtime as you can simply top off the gas tank to keep working.
- Heavy steel deck resists impacts from gravel, roots, and hidden debris.
- Large rear wheels roll smoothly over molehills and uneven soil patches.
Cons
- Requires regular engine maintenance including oil changes, spark plug checks, and air filter cleanings.
- Loud operating volume requires you to wear hearing protection during use.
- Heavy overall weight makes the mower harder to lift into a truck bed or maneuver when the self-propelled drive is disengaged.
Best for: Owners of medium to large properties with tough terrain, thick grass varieties, or slopes who need reliable, continuous cutting power.
Expert Opinion: The PowerSmart gas mower is a rugged, budget-friendly powerhouse that dominates overgrown yards where battery-powered alternatives tend to struggle and stall.
Ryobi Self Propelled Lawn Mower vs Push: Key Differences That Matter
Performance Comparison
When comparing the cutting performance of the ryobi self propelled lawn mower vs push gas models, the differences become obvious in thick turf. The PowerSmart gas engine relies on high-torque combustion to slice through thick, overgrown weeds without losing blade speed. The Ryobi cordless mower uses smart electronics to boost its motor speed when it senses resistance, but it will stall sooner than the gas model in dense, damp clover. If you cut your grass every week, the Ryobi performs beautifully. If you frequently let your grass grow too tall before cutting, the PowerSmart engine is much more forgiving.
Price and Value Analysis
The initial purchase price of these two machines is relatively close, but their long-term cost structures differ. The Ryobi includes the expensive battery and charger upfront, which saves you money on gas, oil, and spark plugs over the life of the machine. The PowerSmart mower has a lower entry cost, but you must budget for fuel, stabilizer, and annual maintenance kits.
Build Quality Comparison
The PowerSmart model features a heavy-duty steel deck that can withstand impacts from small rocks, pinecones, and tree roots without cracking. The Ryobi utilizes a lightweight composite plastic deck. While this plastic deck will never rust or corrode, it does flex slightly when pushed over rough terrain and feels less rugged than the steel chassis on the gas mower.
User Experience Differences
Operating these two mowers offers completely different sensory experiences. The Ryobi starts with the simple push of a button, runs quietly enough to allow for conversation, and emits no exhaust fumes. Storage is simple because you can fold the handles down and stand the mower upright against your garage wall. The PowerSmart requires a pull-cord start, creates significant engine noise, and gives off exhaust emissions. It also requires flat storage to prevent engine oil and gasoline from spilling onto your floor.
Which Should You Choose?
Your choice between these two self-propelled mowers depends primarily on the size of your property and your willingness to perform engine maintenance.
If you own a typical suburban yard of a quarter-acre or less, value a quiet backyard environment, and prefer to skip gas station trips, the battery-powered Ryobi is the logical choice. It offers simple operation, folds away neatly, and runs long enough on a single charge to handle standard lawns.
If you have a medium to large yard with steep slopes, rough terrain, or stubborn weed growth, the PowerSmart gas mower is the better tool for the job. It provides the sustained power and durability needed to tame neglected lawns without waiting around for batteries to recharge.
Frequently Asked Questions
Q: Can I use the Ryobi battery in other lawn tools?
A: Yes. The 40-Volt battery included with the Ryobi mower is fully compatible with all other tools in the Ryobi 40V lineup, including string trimmers, leaf blowers, and chainsaws.
Q: How long does the battery last on the ryobi self propelled lawn mower vs push gas models?
A: The Ryobi 5.0 Ah battery generally provides up to 35 to 40 minutes of runtime under normal conditions. Gas models like the PowerSmart have virtually unlimited runtime because you can instantly refill the fuel tank to keep mowing.
Q: Is the Ryobi composite deck as durable as the PowerSmart steel deck?
A: The Ryobi plastic deck will never rust, making it highly durable against moisture. However, the steel deck on the PowerSmart is much better at resisting cracks and damage from impacts with rocks or thick tree roots.
Q: How loud is the ryobi self propelled lawn mower vs push gas mower during operation?
A: The Ryobi battery mower operates at a much lower decibel level, allowing you to cut your grass in the early morning without disturbing your neighbors. The PowerSmart gas mower is significantly louder and requires operators to wear hearing protection.
Q: Can the PowerSmart gas mower be stored vertically?
A: No. Storing the PowerSmart gas mower vertically will cause engine oil and gasoline to leak into the air filter and carburetor, which can ruin the engine. The Ryobi is specifically designed for space-saving vertical storage.
Q: What kind of fuel does the PowerSmart mower require?
A: The PowerSmart 170cc engine runs on standard unleaded gasoline. It is highly recommended to use fuel with an octane rating of 87 or higher and an ethanol content of 10 percent or less to prevent fuel system clogs.
