EGO POWER+ 22" ALUMINUM DECK SELECT CUT™ SELFPROPELLED LAWN MOWER
Model: LM2206SP
Battery: 12Ah 56V

I love my new EGO!! I wanted to upload some footage of it blasting through every blade of grass in my backyard to show off TURBO mode power!!

I do NOT use self propel. I have always pushed the mower. I like the work out, lol. That being said, I have used the self propel and it does have a loud whine when engaged on this mower. I don't think it's annoying but a lot of people in reviews do.
