Overview

Model # RY40180 Store SKU # 1000858337

Ryobi redefines cordless lawn mowers with the second generation 20-inch 40V Brushless Mower. Featuring gas-like power, this mower has an intelligent brushless motor with load-sensing technology, allowing it to detect and deliver the power needed to maintain an optimal cutting speed. This means the mower will not get bogged down in overgrown patches of grass and, when additional power is not needed, increases run time by saving the battery. The Ryobi Brushless Mower has a large 20-inch cutting deck, and with its mulching or bagging option, you can get the job done quickly and just the way you like. With its push-button start and 7-position single point height adjustment, you're ready to begin in seconds without having to mess with gas and oil. For easy and compact storage, the telescoping handle has quick-release knobs and the mower is designed to be stored vertically. If you have close neighbours or prefer mowing in the cooler evening hours, this whisper-quiet design with high-intensity LED headlights is the perfect solution. This mower is equipped with a 5.0 Ah 40V Li-Ion high capacity battery for extended run time. The included battery and charger are compatible with any Ryobi 40V tools.

Rated 3 out of 5 by from Eco expensive I purchased this item in April 2017 and it cuts the lawn very well. Unfortunately RYOBI's 40 volt batteries don't last. After about 5 years they won't hold a charge any more. While the initial purchase was only $298, a new battery is $199 and you can't get after market replacements. So while it's great to have a quiet lawn mower that doesn't produce CO2, you can buy a lot of gas for $199. Being Eco friendly shouldn't be so expensive. Also, if you can buy the complete lawn mower, battery and charger for $298, a replacement battery shouldn't cost $199 and should last more than 5 years.

Rated 1 out of 5 by from Disappointing Both this lawnmower at the start of summer last year along with the string trimmer. 2 batteries and this meant back and front mown and trimmed on one set of charges. Mower now suffering exactly the same problems as detailed in several other posts - mower lights up but won't mow for more than 5 metres and now won't even start. V disappointing, especially when I see the responses listed about service centres. Doesn't give me confidence I want to take the hour trip...... End of year, so I can decide whether I want to stay with Ryobi/Home Depot or go elsewhere next spring...any thoughts HD?

Rated 4 out of 5 by from Good for basic lawn mowing It’s a very good machine for basic mowing. Very light and easy to use (though turning needs a little more effort). Starting it up is absolutely effortless! But that’s all the mower does (and yes I know - all it really needs to do!). If you hope the mower will pick up anything more than the very light grass clippings from mowing (like dead leaves on the lawn or plugs from airing), that doesn’t happen - I don’t think it’s strong enough for that. The battery lasts (depending on how long and thick the grass is) about 1.5 hours and the collection bag fills up pretty quickly (but also of course depending on how long and thick the grass is). So if you have a well maintained and smaller lawn this really is the perfect machine for you!

Rated 1 out of 5 by from Problem mower I have had moderately good use of Ryobi in the past but this mower was disappointing. It worked fine for about 3 months, then the battery started behaving very strangely. It charged to full lights, plug it into the mower and start mowing, and 2 minutes later, down to half charge. The 5Ah battery is unavailable, so they took the whole mower back and gave me another. This one would start, and stop running as soon as it hit a few blades of grass. My guess is the overload protection was overloaded. I do recommend Ryobi in general for light to moderate duty work, but this mower was very problematic.

Rated 4 out of 5 by from Great lawnmower I really like this lawnmower. It has no problem cutting through long or wet grass. I like when it senses long tougher to cut grass the lawnmower speeds up on it's own to get through it. The downside to this lawnmower is it only comes with one 5ah battery.I don't have a big yard but I can't cut my front and back yard in one charge. Also it takes 3 hours to charge the battery from 0 to 100%. I've looked into getting another battery and it's $200. I would rate this lawnmower 5 stars if it came with two batteries or came with a coupon to get the second battery at a discount. It just feels incomplete with only one battery.

Rated 5 out of 5 by from Fantastic purchase Husband has used twice so far and he LOVES it. He's always been a fan of this brand and this is no exception. It has a lot of power and looks very sporty too, almost like a hot wheel disguising itself as a lawn mower. He loves it so much that we also just bought a same brand weed wacker with interchangeable battery to replace our non-compatible-battery which battery performance has been failing. So now we have 2 batteries which last a good while that he can interchange for both machines, we're thrilled because before it took multiple charging s just to complete our property. He loves the weedwacker too, thinks it has more power than a gas.

Rated 1 out of 5 by from No receipt , NO WARRENTY Bought my mower 2 years ago and misplaced the receipt.. Worked fine till the other day after cutting lawn. Tipped it on it's side to make sure clean then put it away. Now the lights comes on but that's it. Even my battery says July 2016 but with no receipt, NO WARRENTY from Ryobi. The only service center I can go to within 300 km and even they say it's made in China and it can take 3 hrs to find the problem due to all the wiring. Last repair on one was 3hrs $265 Even they don't like them. My mower looks brand new but now it's garbage. My gas mower lasted 15yrs and now guess what I'm going back too.

Rated 1 out of 5 by from Disappointing mower and customer service from Ryob I have had nothing but problems. I can't go more than 12' without the mower shutting itself off. I turn around, mower shuts off. Machine spent 3 weeks at a certified service outlet, they gave me a new battery. That battery didn't charge. Got a new battery from Home Depot. The latest battery charges, but the mower still shuts off every 12'. I have spoken, emailed, messaged Ryobi and it's frustrating every time. Today I was told they don't believe customers, only their technicians. Well, maybe they should listen to their customers. I sent them the serial number, it should have been registered as a warranty repair in my file, since they sent me a new battery. But the guy today said he would start a file. I am not going to take it back to the service centre. I can't sell it because it's a lemon. Home Depot, you need to do better.

This 40v battery is included and is rated at 5amp. Do the lesser amp 40v still fit this lawnmower? Ie; 40v 3amp or 40v 4amp?

Asked by: Darrald
Hi Darrald, Thanks for the question. All of our 40V batteries are compatable regardless of Ah rating. We hope this helps. Ryobi Canada Team.

The battery of this mower is good but the cut is not good. Usually need to mow it 2-3 times to cut the grass. This happens from day 1 when I purchased it. Does anyone has the same experience? Is there a way to solve this problem?

Asked by: Vincent
The cut has been above the norm, the battery the first year did a large front and back yard with one charge, the second season it took two charges, then the battery quit shortly after the start of the third season, contacted the manufacturer and had a new one battery from the States in a week, been great since, love the way it automatically speeds up when the going get tough

Had this lawn mower for a year. Now it cuts out when mowing. When I lift up the back wheel and try and try and mow it works. Ideas how to fix - I want to use it normally in 4 wheels.

Asked by: Sam777
Be sure all of the clips on the side of handles are fully locked in place. I had similar issue and it seemed to work after ensuring they are all securely locked in.

I don't want to use the bag, is there a side chute?

Asked by: RayG
No side chute no - but you can still mow without a bag - clippings just drop out the back.  There's a flap to stop clipping spraying all over you if you don’t use the bag.

Re 20-Inch 40-Volt Lithium-Ion Brushless Cordless Push Lawn Mower with 5.0 Ah Battery & Charge, is it okay to use extension cord to connect the charger to the electrical socket for recharging? For some battery, this is not allowed, as per its manual.

Asked by: Goodguy
I've had my 40v cordless lawnmower for two years now and because the battery is detached from the lawnmower all I do is move it when it needs to be recharged and plug the charger into an outlet in my house. It takes less than an hour to fully charge the battery and it's ready to go. Because of the portability I don't think one needs to worry about plugging in the charger with an extension cord. I also store my chargers and batteries inside my house for wintertime.

Is it harmful to the battery if it is left in the charger until the next time I cut the grass? And repeated?

Asked by: Gman
Hi Gman, Thanks for reaching out to us. If you leave the battery on the charger until next use it will not cause any harm or damage to the battery or charger. If will have a minor constant electrical flow running through it but will keep it at 100% charged. We hope this information helps. Thanks, RYOBI Canada.
