If you are looking for a simple way to cut your lawn without dealing with gas, oil, or loud engine noise, this ryobi 40v 20 self propelled lawn mower review will help you fast. After using this mower for weeks on thick grass, light hills, and regular suburban lawn care, I can say it feels far more powerful than most people expect from a battery mower. It is easy to use, quiet, and surprisingly strong for small to medium yards. If you want a low-maintenance mower that still feels capable, this Ryobi model deserves a close look.
What Makes the Ryobi 40V 20 Self Propelled Lawn Mower Different?
The biggest reason people buy this mower is convenience. This mower removes most of the annoying parts of lawn care. That alone makes it appealing for many homeowners in the USA.
Instead of pulling cords or filling gas cans, you push a button and start mowing. The self-propelled system also helps a lot on uneven yards or sloped driveways. I noticed this right away during my first mow.
This mower also belongs to the Ryobi 40V battery ecosystem. That matters because many people already own Ryobi outdoor tools like trimmers, chainsaws, and blowers. Being able to swap batteries saves money and space in the garage.

What I Like
- Easy Push Button Start: I loved not dealing with gas or pull cords anymore. I pressed one button and started mowing in seconds. That made yard work feel much less stressful.
- Self-Propelled Drive Feels Smooth: The rear-wheel drive system worked well on my slightly uneven lawn. I noticed far less arm fatigue compared to my old push mower.
- Quiet but Powerful Cutting: This ryobi 40v 20 self propelled lawn mower review would not be complete without mentioning the cutting power. It handled thick grass better than I expected while staying much quieter than gas models.
- Compact Storage: I fold the handle down and store it upright in my garage corner. That saved more space than my older gas mower ever did.
- Very Low Maintenance: No oil changes. No spark plugs. No fuel smell. That alone made ownership easier for me.
- Battery Compatibility: I already had another Ryobi 40V tool, so swapping batteries between tools was very convenient.
- Good for Neighborhood Use: In many suburban US neighborhoods, quieter battery mowers are becoming more common. I could mow early in the morning without feeling guilty about noise.
What Could Be Better
- Battery Runtime Can Feel Short: If your grass is tall or wet, battery life drops faster. I got about 35 minutes during heavier mowing sessions.
- Extra Batteries Are Expensive: A second battery almost feels necessary for larger lawns. Unfortunately, replacement batteries are not cheap.
- Plastic Deck May Worry Some Buyers: The deck feels solid enough, but it does not feel as rugged as steel gas mowers. I found myself being more careful around rocks and curbs.
- Bag Fills Quickly: The grass bag works well, but I had to empty it often during peak growing season.
- Self-Propelled Speed Takes Practice: At first, the drive speed felt slightly aggressive. After a few uses, I adjusted to it.
- Not Ideal for Large Properties: This mower works best for small and medium yards. If you own over half an acre, you may want a riding mower instead.
Ryobi 40V 20 Self Propelled Lawn Mower Performance Review
The overall performance surprised me in a good way. This mower feels stronger than many people expect from a cordless mower. That is the main takeaway from my testing.
I tested the mower on normal suburban grass, slightly damp patches, and thicker overgrown sections near my fence line. It cut cleanly most of the time. The brushless motor also adjusted power automatically when the grass became dense.
Cutting Power
The cutting power is honestly the biggest surprise. Many people still think battery mowers are weak. I thought the same before trying this model.
The mower handled:
- Tall grass
- Thick patches
- Dry leaves
- Pinecones
- Slightly uneven ground
The mower slowed slightly in very thick grass, but it never completely bogged down during my testing.
That makes this mower a realistic gas alternative for many homeowners.
Self-Propelled System
The self-propelled feature changed the entire mowing experience for me. It reduced effort a lot during longer mowing sessions.
The rear-wheel drive system helped especially on:
- Mild hills
- Side slopes
- Uneven ground
- Wet patches
I usually kept the speed closer to turtle mode instead of maximum speed. Slower movement also improved cut quality because the blades spent more time over each grass section.
Runtime and Charging
Battery runtime depends heavily on lawn conditions. That is important to understand before buying.
Here is what I experienced:
| Lawn Condition | Estimated Runtime |
| Dry Short Grass | 40-45 Minutes |
| Medium Grass | 35-40 Minutes |
| Thick or Wet Grass | 25-35 Minutes |
| Self-Propelled Heavy Use | Slightly Reduced Runtime |
Charging took close to one hour for me.
If you own a small suburban yard, one battery is usually enough. If your lawn is larger, I strongly recommend buying a second battery.
Build Quality and Design
The design feels very homeowner-friendly. Everything feels simple and easy to understand.
The folding handle system works quickly. I also liked how lightweight the mower felt compared to older gas machines.
Handle Controls
The controls are easy to learn. After one session, everything felt natural.
You get:
- Push-button start
- Adjustable self-propel speed
- Height adjustment lever
- Safety key
- Folding handles
The mower also feels balanced while turning around corners.
Height Adjustment
Changing cutting height is simple. One lever controls all four wheels. That saves time.
The mower offers seven height positions. That gives enough flexibility for:
- Bermuda grass
- Kentucky bluegrass
- Tall fescue
- Mixed suburban lawns
For most US homeowners, that range is more than enough.
Storage Convenience
Storage is one of the most underrated features. This mower folds vertically and takes up little room.
That matters if you:
- store tools in a small garage
- use a backyard shed
- live in a townhouse
- have limited storage space
I personally appreciated this more than expected.
Noise Levels and Comfort
The quiet operation completely changed how mowing feels. That is one of the strongest points in this ryobi 40v 20 self propelled lawn mower review.
Compared to my old gas mower:
| Feature | Ryobi 40V | Traditional Gas Mower |
| Noise | Much Quieter | Loud |
| Vibration | Low | High |
| Startup | Push Button | Pull Cord |
| Maintenance | Very Low | High |
| Smell | None | Gas Fumes |
| Weight Feel | Lighter | Heavier |
I could easily listen to music while mowing. I also did not feel exhausted afterward.
My Personal Experience with Ryobi 40V 20 Self Propelled Lawn Mower
When I first switched from gas to battery power, I honestly expected compromises. I thought I would lose cutting power or runtime. After several weeks of use, my opinion changed quite a bit.
The mower started instantly every time I used it. That alone made lawn care feel easier. I also noticed how much quieter my yard became during mowing sessions. My neighbors probably appreciated that too.
The self-propelled system helped a lot more than I expected. My backyard has a small incline, and my older push mower always felt tiring there. With the Ryobi mower, I finished faster and with less effort.
I also liked how clean the mower felt overall. There was no gas smell in my garage. No leaking oil. No dirty spark plug maintenance. It simply charged and worked.
The cut quality looked even across most of my lawn. Around thicker patches, I slowed down slightly and the mower handled it fine. I also tested bagging mode during fall cleanup, and it picked up leaves surprisingly well.
A few things did stand out during long sessions. The battery drains faster in heavy grass. That became noticeable during spring growth. I also found the grass bag slightly small for bigger cleanup jobs.
Still, the overall experience felt modern and simple. This mower made lawn care less frustrating for me.
Real Usage Results
- Finished my small yard on one battery
- Reduced mowing effort on slopes
- Easier startup compared to gas mower
- Garage stayed cleaner without fuel
- Much quieter than expected
- Compact storage saved space
- Cut quality looked clean and even
- Runtime dropped in thick wet grass
- Needed slower speed for best cut
- Battery charging felt fast enough
Comparing With Other Brands
I’ve also used Greenworks and Ego battery lawn mowers before trying the Ryobi model. Each brand has strengths, but they feel slightly different in daily use. Ryobi focuses heavily on simplicity and ease of use, while Ego usually pushes more raw power and Greenworks often competes on value.
For normal suburban lawn care, all three brands can work well. The biggest difference comes down to runtime, comfort, battery ecosystem, and price.
Ryobi vs Ego: Quick Comparison
| Feature | Ryobi 40V 20″ Self Propelled | Ego Power+ 21″ |
| Power | Very Good | Excellent |
| Runtime | 35-45 Minutes | 45-60 Minutes |
| Weight | Lighter Feel | Slightly Heavier |
| Noise | Quiet | Quiet |
| Price | More Affordable | More Expensive |
| Storage | Excellent | Excellent |
| Best For | Small-Medium Yards | Medium-Large Yards |
The Ego mower feels stronger overall, but it also costs more. Ryobi gives better value for many average homeowners.
Ryobi vs Greenworks: Quick Comparison
| Feature | Ryobi 40V | Greenworks 40V |
| Build Feel | More Refined | Simpler |
| Self-Propel System | Smoother | Decent |
| Battery Ecosystem | Large Tool Selection | Good Selection |
| Runtime | Moderate | Moderate |
| Ease of Use | Excellent | Good |
| Noise | Quiet | Quiet |
Greenworks is often cheaper, but Ryobi felt more polished during daily use.
Ryobi vs Gas Mower: Quick Comparison
| Feature | Ryobi 40V Self Propelled | Gas Lawn Mower |
| Startup | Instant Push Button | Pull Start |
| Maintenance | Minimal | High |
| Fuel Cost | None | Ongoing |
| Storage Smell | Clean | Gas Smell |
| Noise Level | Low | Very Loud |
| Power Consistency | Good | Excellent |
| Long Runtime | Limited by Battery | Better |
Gas mowers still win for huge properties, but battery convenience is hard to ignore once you experience it.
Who Should Buy the Ryobi 40V 20 Self Propelled Lawn Mower?
This mower works best for homeowners who want easy lawn care with less maintenance. That is the clearest answer after my testing.
Best For
- Small to medium lawns
- Suburban homes
- Homeowners tired of gas maintenance
- People wanting quieter mowing
- Older users wanting easier handling
- Buyers already using Ryobi 40V tools
If your yard is under half an acre, this mower makes a lot of sense.
Who Should Think Twice?
- Owners of very large properties
- Commercial landscapers
- Buyers needing over one hour runtime
- People who prefer steel deck durability
- Users mowing extremely thick fields regularly
Those users may want a stronger 60V or gas-powered mower instead.
Recommendation
After spending real time with this mower, I understand why so many homeowners are switching to battery power. The Ryobi mower removes many common frustrations tied to gas equipment.
I would personally recommend this mower to people who want easier lawn maintenance and quieter operation. It especially fits suburban homeowners with average-sized yards.
If you already own Ryobi 40V tools, the value becomes even better because you can share batteries across your equipment.
That said, I would still suggest more research if:
- your property exceeds half an acre
- your grass grows extremely thick
- you mow professionally
- you need maximum runtime every session
For normal weekly lawn care though, this mower performs better than many people expect.
Final Thoughts on This Ryobi 40V 20 Self Propelled Lawn Mower Review
The biggest strength of this mower is convenience. That is the main conclusion from my experience.

I also think this mower fits modern suburban lawn care very well. Quiet operation, battery convenience, and compact storage all matter more today than they did years ago.
The runtime and battery cost are the biggest drawbacks. Still, if your lawn size matches this mower’s strengths, it delivers a very solid overall experience.
