Ryobi vs EGO Mowers

We have recently reviewed the Ryobi 40 volt 20″ Brushless Push mower and the Ryobi 40 volt 20″ Brushless Self-Propelled mower and in all the comments on YouTube, there were multiple people who asked for the mower to be compared the EGO 56 volt Self-Propelled 21″ mower.  We sat down and came up with a plan to compare the two brands in a fair manner.

First, The EGO 21″ Self-Propelled mower comes with a 7.5Ah 56 volt battery that would give EGO an edge on run-time, but the 21″ EGO Push mower comes with a 5.0Ah battery, so we decided to even the playing field and use a 5.0Ah battery when comparing the EGO to the Ryobi.  

NOTE:  Because of our battery change, the run-time of the EGO 21″ Self-Propelled mower will be less than normal. If you buy the kit, you will get better results.

They Almost Look The Same!

When you place the Ryobi 20″ 40 volt mower next to the EGO 21″ 56 volt mower, they look very similar.  LED lights seem odd on a mower and both of these units have them.  The battery compartments on each have a see through cover.  Both models fold up pretty close to the same and also have a single lever that adjusts the mowing height.  Although the mowers seem to share some of the same features, they do not seem to share the same build quality.

The EGO mower has a dual wall plastic deck while the Ryobi has a deck that is reinforced around the front and back, but the sides are left as a thin single layer of plastic that is flexible.  We have rubbed up against a tree and had the blade gouge the inside of the deck on the Ryobi.  The Ryobi also has some loose wires where EGO has wires in a wire loom.

How Long Do The Mowers Run?

The battery run-time on any tool can vary, but on mowers we see a large swing in the run-time due to the height of grass cut, thickness of grass, species of grass, amount of weed, moisture content and temperature.  In our tests, we used open lots to allow for a constant speed of mowing along with cutting the same height and moisture content of grass.  One lot was recently cut with a normal amount of grass that needed to be cut and the other lot was let go an extra week, providing a lot of grass to cut along with some weeds.

In the first round, while cutting normal grass one would if they keep up on their yard, the Ryobi was able to cut about a 1/4 acre of lawn and the EGO was able to cut just over a 1/2 acre of grass on a single battery charge. (Remember we used a smaller battery in the EGO)  This test was performed with no obstacles so more lawn would be cut in this test than a normal lawn.

In the second round, we started mowing the taller grass that had not been mowed in two weeks.  Neither mower had issues cutting the grass, but both seemed to ramp up the speed of the blade to keep up.  Since the amount of grass cut decreased, we found it best to count the numbers of passes that were cut by each mower.  While cutting the taller grass, the Ryobi was able to make 14 passes and the EGO was able to make 41 passes.  There was again a significant difference.

Batteries & Charge Time

While testing, we worked hard to create a very fair situation, going so far to reduce the size of the EGO battery to compare a 5.0Ah battery to a 5.0Ah battery.  To keep the grass the same moisture and height, we mowed on the same days at very close to the same times.  What made this hard in this test and in the general review of the Ryobi is the charge time needed on the 40 volt 5.0Ah battery.  Most of the time when the Ryobi battery was removed from the mower it was very hot.  We would place it on the charger and it would need about 45 minutes to cool before it started charging.  Once it started charging, it took about 3 hours for it to charge fully.  That slowed the mowing down as it was nearly a 4 hour wait time between cuts.

The EGO battery charger had an integrated fan and is able to charge the battery in 45 minutes without any wait time for cooling.  The 7.5Ah battery that comes with the EGO would charge in about 60 minutes.  Either way, if one had two batteries they could keep mowing without stopping as one battery would be charging while you used the other.

Cost of Ownership

If you watched our YouTube reviews on the Ryobi mowers you would have seen us recommend an extra 5.0Ah battery when purchasing the Ryobi mower so you were sure to get 40 minutes of run-time because the charge time was so long.  While the Ryobi mower might be less expensive initially, after the second battery purchase, the prices become much closer.  But since both of these companies have other outdoor power equipment, one could pick up any other tool with a large battery and save money and gain more tools.  Our point here is to look at more than just the purchase price.


Both the EGO and Ryobi mowers have their customer base.  EGO has better build quality and much more run-time with a great charge time.  Not everyone needs the run-time, so if you live in the city with a very small yard, the Ryobi mower will work for you with a single battery.  Therefor the cost savings on the Ryobi makes a lot of sense.  But if you have a lot that is over a 1/4 acre and you are going to try to save money by purchasing the Ryobi, you might end up spending the same amount or more on the mower and batteries than if you would have purchased the EGO.  Our recommendation for people with a 1/4 acre lot or larger is to purchase the EGO because of the run-time and build quality.  Making these decisions are never easy, especially when talking about mowers that cost 4-500 dollars.
