Is This the Future of Lawn Mowing? OPINIONS WANTED!

What happens here

The presenter demonstrates engaging the blades of the electric mower and adjusts the blade speed settings on the digital display. He then uses a decibel meter to measure the noise level of his speaking voice (approx. 78 dB), the gas mower with blades engaged (approx. 100 dB), and the electric mower with blades engaged (approx. 90 dB). He also measures the noise of an old-school Kubota diesel mower (approx. 99 dB). He concludes that the electric mower is significantly quieter.

Goal: Quantify noise reduction and demonstrate blade controls

Tools and materials

  • Decibel Meter LONVOX — Measuring and comparing noise levels
  • Kubota ZD25 Diesel Mower Kubota — Testing noise levels for comparison

What they say

here is our setup. A lot of shadows here today. I'm sorry. So, we show we're in neutral. We've got a screen here that we can scroll through. Um 4 hours. This one has been ran. These are our blade speeds. Let's just go ahead and turn that on. Okay, so those are our blades. Our blades are active. I'm sorry, guys. The reflection is pretty bad right here. Uh, we'll scroll through again. This is our max traction speed, and you can go faster. You have to have it unlocked. There's a code that you can punch in, I'm told. I don't know a lot about it. I'll learn. This is our blade speed. So, right now, we're set in the very, very middle, but check it out. Watch this. [Laughter] That's how you engage your blades. Simply a switch. It's not a solenoid. It's just a toggle switch. We got our light switch right here. Got several other adjustments right here. This is how much battery we have left. And we are not going to run a full battery out of this machine today. We're just not going to do it. There's no way. Uh again, we're probably at about a 70% on our battery. Um has a super comfortable seat, very plush. Armrests are nice. I mean, this is just what you'd expect out of a commercial mower. Uh to adjust your blade height, and we've already got our blade height adjusted on the other one, and we'll put this one just to match it. So, adjust our blade height. We mash this nicely knurled foot pedal. Mash it up. This has a magnetic retention system in it. Very cool. And this is where we need to be pretty much. Now, when we raise our blade up cuz we got to go over curbs. Let's say we're a landscape contractor or there's some rocks like the Stony Ridge Farm. Then we can mash this and it locks our blade in the upright position. We want to fix that. We mash it and drop it all the way down. When we mash it all the way, it automatically flips that tab. There we go. So, the blade is in the up position. Now, we're in the down position. This mower is on. This mower is running. This mower is is I mean, it's on. So, um decibel meter wise, I think it's time we get the decibel meter and we engage the u blades on this and we see what it sounds like noisewise and we give you a full report on that. All this is fun stuff, but can you carry your water bottle? Mhm. We got a big old water bottle holder for tumblers and a regular water bottle holder for regular water bottles. And we've got USB charging right here. Got a little package tray and you can fit your phone in there also. Very, very…
