The Ryobi 20″ 40v mower seems like a mower you will either love or hate. I think going into it with the right expectations is probably key. Let’s take a closer look.






Ease of Use



This mower is very light, weighing in at only 44.7 lbs so it is very easy to handle. It’s also very easy to fold up and store away.

The 20″ deck sits on 8 inch front tires and 10 inch rear tires. Deck adjustment happens with one lever and adjusts 7 positions between 1.5 and 3.75″.

The only options for this mower are either mulching or bagging the clippings, there is no side discharge for this mower.

A telescoping handle will make it easy for a person of any height to operate this mower.

One of the nicest features on this mower is the load sensing power. So when the mower detects thicker grass it will provide more power to the blade motor. Otherwise it will back off a bit to conserve batter life.

Speaking of, battery life seems to be the biggest pain point on this mower. The Ryobi 40v mower comes with a 5.0 Ah battery which is supposed to last 38 minutes. In reality it seems most people get about 20 minutes average.

While recommended for properties between 1/4 to 1/2 acre it seems like 1/8 to 1/4 acre properties would be more ideal. To fully charge the battery it takes 3.5 hours.

The quality of the cut seems to be on par with similar gas powered mowers.

Final Thoughts

The Ryobi 20″ 40v RY40180 is now on its 2nd generation so hopefully some of the kinks have been worked out with the battery life. There is a 5 year warranty on this mower but a lot of people have mentioned it is an absolute pain to deal with Ryobi support.

Also to note is it is backed by a 90 day no risk guarantee, so you can try it and if the mower doesn’t work for you just make sure to return it before the 90 days is up and get something different.
