In addition to being compatible with other RYOBI machines, this mower's lithium-ion battery lasts up to 40 minutes on a full charge. If your lawn is well-maintained, this gives you plenty of time to mow your yard before you need to recharge the battery. The mower can house up to two batteries. This allows you to mow for an extended period, especially handy if you have a larger lawn. You may find the batteries drain more quickly when you mow long or thick grass. Fortunately, RYOBI's batteries recharge faster than others – you can charge a battery to full capacity in 90 minutes.

RYOBI 40-Volt Brushless RY40180: What you need to know

The RYOBI 40-Volt mower is best for lawns that are half an acre in size or less. The mower has a 20-inch cutting path and seven cutting-height positions, ranging from 1.5 to 3.75 inches. You can easily adjust the height with a lever located on the left side of the mower deck.

When you finish mowing, the handle folds down, which makes the mower easy to store. This is extremely helpful if you have limited space in your garage or shed.

RYOBI 40-Volt Brushless RY40180: Features & performance

Unlike gas-powered mowers, the RYOBI 40-Volt starts instantly with the press of a button and runs quietly without disturbing your neighbors or emitting noxious fumes. It isn’t self-propelled though, so you need to put some work into moving it around.

This is a good electric lawn mower if your goal is to be environmentally friendly. It comes with a mulching option that grinds down grass clippings so you can reuse them for gardening instead of throwing them away. It also frees you from the yearly maintenance and fuel and oil that traditional mowers require.

This mower weighs just 55 pounds with the battery installed. Because it’s lightweight, it’s somewhat easier on your back and knees. Still, it may be difficult for some to maneuver on hills or steep grades because it isn’t self-propelled. This RYOBI also does not have a side discharge. It comes with a rear bag that collects grass clippings as you mow.

Should you buy the RYOBI 40-Volt Brushless RY40180?

The RYOBI 40-Volt 20-inch cordless mower is one of the best electric lawn mowers for homeowners with small lawns who have limited storage but need efficient cutting power. The added value of being capable of using up to two batteries that work with other RYOBI lawn equipment makes this electric lawn mower well worth considering. The fact that it isn’t self-propelling could be a major drawback for some buyers though.

After three years of use, and extensive research on the competition, I believe the Ryobi 40-volt cordless lawn mower is the best mower for the money, for people with small lawns. My mower is the RY40170 20″ brushless mower. It came included with two 4 amp hour batteries, is capable of mulching and bagging, only weighs 44 lbs (plus battery), and comes with a 5 year warranty. It has seven cutting height adjustments (from 1.25″ – 3.75″) that you can easily adjust with a single lever and the handles fold down flat making it super easy to store. This is especially helpful if you have limited space in your garage or shed. Having two batteries included is a big bonus. Based on the reading I’ve done, with the included batteries, the Ryobi has the longest run time of any cordless mower (over 1hr). With a robust 40 volt ecosystem, its batteries can also be used to power other Ryobi lawn equipment, such as a string trimmer and blower.

PROS OF BATTERY MOWERS IN GENERAL

Three years ago, my Ryobi mower was among the first cordless electric mowers I had seen. Now, however, it seems that the cordless revolution has truly arrived. Battery operated mowers offer everything you like about mowing a lawn without all of the things you hate. No gas, oil, cords, or noise.

They are environmentally friendly and require none of the yearly maintenance that traditional mowers require. They start instantly with the press of a button, run much more quietly and, of course, do not emit exhaust fumes. Everyone I know who has made the switch has said that when they owned a gas mower they weren’t particularly offended by the noise and inconvenience of gas, however after switching, they couldn’t dream of going back.

PROS OF THE RYOBI

The main advantages of the Ryobi mower are that:

It’s very lightweight and maneuverable
Its folding design makes it very portable and easy to hang
Its runtime is very long, amongs the best on the market
Its rechargeable lithium-ion batteries can be used to power your other compatible Ryobi cordless lawn equipment.

CONS OF THE RYOBI

The main disadvangaes are as follows:

There is no option of a side discharge
It’s not self-propelled. Although it is lightweight, it may be difficult for some to maneuver on hills or steep grades . A self propelled version is now available, which I will hopefully get a chance to test
Its charge rate is good, however a ‘quick charge’ option would be good

POWER

Over a three year period, I’ve used this mower in wide range of conditions – super thick grass, wet grass, new sod, new seed, mulching leaves, bagging, different cut heights etc, and its power and performance did not disappoint.

It can handle tough grass without any issue, and given how light it is, it did well on newly seeded areas as well. When the mower hits a patch of lawn that is tougher it adds more power. You can hear the motor speed up to compensate. This is done automatically in order to conserve battery usage.

In my experience I get approximately 40 minutes from a full charge of one 4 amp hour battery. My lawn can usually be done in about 30 minutes, so I’m able to do it all with one battery. And that usually leaves enough juice left to do the trimming as well. Not that I need to use one battery for both. The mower and trimmer both came with 2 batteries, so I could easily do my neighbors lawns as well if I needed too. I bought the blower without batteries, when I realized how much extra capacity I had. I believe the current model of this mower now comes with a single 5.0 Ah battery.

Ryobi’s batteries charge to full capacity in 90 minutes. So technically, if you had three batteries, you could basically mow indefinitely. The batteries each have 4 led lights on them so you can check their power level and you can see their charge progress as they’re charging. Even though the mower could be used to mow 1/2 acre or larger; in my opinion, it is best suited for lawns that are between 1/3 of an acre to 1/2 an acre. That leaves you plenty of capacity for those days when the grass is super thick, or if you need to cut when it’s wet. And, truthfully, I think most people would want a self-propelled mower for lawns larger than 1/2 an acre.

DURABILITY

Over my three years of ownership I only had two things break on the mower. The first item was the plastic battery cover. One of the hinge pins broke when I was opening it. It doesn’t open quite far enough in my opinion. I was able to fix this simply by putting a bent nail in it’s place. The other item that broke, was the rear protective shield. See photo. It basically ripped off. This item receives a lot of wear, so perhaps it should be made from metal instead of plastic and rubber. I called Ryobi about this problem and they mailed me a new one free of charge, so that wasn’t too big of a deal. It was fairly easy to swap out.

ALTERNATIVES

The starting price of the Ryobi is comparable to gas mowers, while also having comparable power. It cuts just as good as a gas mower. In fact, it is the same style blade. Similarly sized gas push gas mowers, however, weigh between 60 and 70 lbs. So the Ryobi pushes a bit easier than a push gas mower in my opinion. In comparison to other battery powered mowers, it’s main competitor is the more espensive EGO mower. The design of the Ryobi isn’t quite as refined as the EGO, however it offers a more appealing value proposition in my opinion. Other 36V cordless mowers look like reasonably good alternatives, but their power and feature sets just don’t compare.

Conclusion

In conclusion, I highly recommend this mower. Ryobi offers a great combination of features at a reasonable price. It’s perfect for a small to medium-sized lawns, and especially attractive if you plan to buy other tools that can use the 40-volt battery architecture. It’s very light, very portable, does an excellent job cutting, and has ample run time. On top of that, it has all the benefits of a cordless electric mower – ie. quiet, no maintenance, easy storage, easy to start, etc.
