We test the electric lawn mawers by driving each through each test battery (no intention, because we run the actual battery test) and yes, we also mawa of goods. There are some product categories where we collect, at that time, tons of tons, but despite our best efforts, the data alone cannot give us a complete picture of which product performs the best. Taking them to the yard is the best way to help filter and understand through the data we have.
Battery test
Let's start with those battery tests. It is not very complex, but it can be a bit difficult to install physically. To measure the voltage and pull the grass cutting machine during the operation, we have to insert our measurement devices between the battery and the grass cutting machine. The physiological process varies slightly from grass cutting machine to grass cutting machine, but once set is set, we get a remedy for DC voltage and the Emps moving between the battery and grass cutting machine, which gives us an idea of motor power (in wats) of the grass cutting machine.
We take these measurements on zero load, which means that we are not cutting grass at that time or otherwise provide any resistance against the blade, which will change the numbers, making them higher to calculate the high boundaries of motor's power. Our next round of updates of the test will also include those upper power boundaries.
Rpm test
Yes, we completely measure the blade RPM in electric mawers. In CNET, the Eagle-Idered lab staff has developed the ability to count dozens of revolutions per second in super accurate fashion. I am joking, although we have a meter for him. In fact, we take a part of reflective tape and position that is on the grass cutting machine blade, then aims to the measurement equipment so that the laser light overlap the tape and we get an accurate reading on the blade RPM.
You can see our test meter in blue in the center under the security glass.
Now, if we combine those numbers with others such as the length of the blade and the weight and some of our motor power calculations, we can estimate things like force, in Newton, the blade is engraving on grass. Those numbers are not highly helpful. Most people will not have an idea that 5 newton is comparable to force. We are more familiar with some people to compare power output; In this case, horsepower.
Gas-operated push mawers differ in horsepower, but most of them land in 3 to 5-HP range. For our next update, we will have the upper limit number, but you can see that the lower limit in horsepower for the electric mawers we tested ranged from about 0.1 to 0.6hp. He is not much. Generally, you should expect the electric mawers triple to look at their upper borders, so we are looking at 1.75hp ballpark. You have to work hard to find retail gas-operated push mawers operated below 2HP.
noise level
We often talk about sound levels, especially with outdoor-type equipment. Historically these external gas-powered equipment have been very loud. (When all your neighbors are getting early in weekends, try to sleep.) With the advent of electric power tool platforms, it is all changing. When you remove the day, your neighbor can pay attention to the care of the lawn.
We tested the decibel level for the mawers from the perspective of a person operating a person. We stabilize and measure a decibel meter. The results were not very surprising, our cool grass cutting machine was the smallest, 13 inches of lieutenant on 68.6DB, and the most vigorous was the most powerful grass cutting machine, ego on 86.7DB.
Speed test
You can usually think of moving forward about mowers at a certain rate, in particular, at whatever rate you carry forward. The increasing number of mawers is now coming up with self-powered options. Many of these electric-quarters mover allow you to use the function when the blades are not running.
We measure how fast the motors move in miles per hour. You will not visit any on-ramp with these, but if you plan to use this mode, it can help you decide which one to take or pass. Ryobi had the most wide range to choose, but the fastest grass cutting a cutting machine was slightly reduced. At the top at Ryobi 3.03mph and Greenworks Pro on 3.33Mph.

Like this cobalt model, some mawers can hit grass clippings.
