6 reasons to buy

  • The Greenworks MO80L510 starts easily and runs smoothly. It has a push-button start and is lighter and easier to move around than gas mowers. It also has extra features like an adjustable throttle for controlling speed. (40 reviews)

    • “Starts easily and runs very smoothly.”

    • “Happy with ease of start/stop and much lighter/easier to maneuver than my gas mower.”

    • “Push-button startup was easy”

    • “It is easy to use and has ample speed adjustment from very slow to a good pace for longer passes. Easy height adjustment for grass height and handle height for comfort.”

    • “Starts right up with no effort at all... The height adjustment is a single lever for all four wheels and it works incredibly well!”

    • “Taking care of my yard is way easier with this battery-operated mower.”

    • “Just hold down the mowing arm and push a button and it starts right up”

    • “a couple of twists and it's ready to mow out of the box. No fumbling putting together.”

    • “It is very well built and so easy to maneuver.”

    • “The self-propelled function is great.”

  • The mower is described as quite powerful and can easily cut through tall and thick grass. It also has an engine sensing feature that adjusts power when it hits heavier grass. (37 reviews)

    • “The mower works very well and was able to cut down dry 12” grass with ease.”

    • “my grass was very deep and overgrown because it hadn't been cut in over a month... but this mower plowed right through it just like our (now deceased) gas mower could.”

    • “The mower never bogged down, cut consistently and evenly, handled it like a champ.”

    • “The engine sensing feature that detects when you get to heavier, thicker or taller grass. The engine compensates and you hear it spool up to a higher rev and it never bogs down.”

    • “Like it’s power and clean cutting.”

    • “My main nervousness was with battery life, and cutting power and this mower delivers on both!...The grass was deep and a little wet... the motor didn't bog down even a little bit. Impressive!”

    • “Battery is good for almost an hour and a half for routine every week mowing. The 75 minutes battery life advertised is when the grass is extra high and thick and using the self propel feature 3/4 of the job.”

    • “battery lasted long enough for me to get my front yard cut and half of my backyard so their claim of battery life/sq ft coverage is accurate.”

    • “The charger got the battery from 0 to 100% in about half hour.”

  • It's about half as loud as gas mowers, so you can listen to music without turning up the volume too much. (22 reviews)

  • The mower is electric. This eliminates the need for gas, plugs, oil, and pull starting. It also does not produce exhaust smell. (19 reviews)

    • “No fuel or oil to bother with, no smelly exhaust, storing with it's space saving set up is great.”

    • “I could not be happier with it, and would never go back to a gas mower, oil changes, spark plugs, new filters, draining the gas for winter, etc.”

    • “The ease of use, lower noise level and less maintenance is a huge benefit and that is why I have gone all electric. No oil, gas, spark plug or filters.”

  • Easy to store due to its space-saving design. The large wheels help it move over rough and sloping ground, and it has a safety feature that locks wheels when not in use. (8 reviews)

    • “Storing the mower vertically in my shed saves a lot of space!”

    • “And you can fold it up to store for winter”

2 reasons not to buy

  • Some users have said that the self-propelled feature is hard to turn on because the instructions aren't clear, which can be confusing. (11 reviews)

    • “The only catch was at first it appeared the self-propel feature was not working. I read the manual etc and called their support line, hold time was less than a minute on a Sunday afternoon, and it turns out that with this model you have to push and hold the start button, squeeze the motor bar, AND squeeze the self-propel bar BEFORE releasing the start button... it doesn't say this in the manual.”

    • “There is a 15 minute learning curve to use the engage lever so you let it go a second before you go around trees, posts, etc.”

    • “My main ding on this mower is with the self propelled feature. There is a safety bar above the handlebar that you have to hold to keep the mower running. Below the handlebar there is a drive bar to engage the self propulsion that you have to hook with your thumbs.”

    • “Make sure to release the self-propulsion a few feet before you actually want to stop or turn.”

    • “the self propel function is great-takes a little practice to stop mower before it hits something.”

    • “That was until the self propelled feature stopped working a minute into my third use!”

    • “One son was helping me cut the overgrown grass and tried the self-propelled mode and it nearly took off from him”

    • “The self-propel feature works from the rear wheels, so that takes a little getting used to if you're used to a front wheel drive one. (You can't just lift the front to stop moving.)”

    • “the moment I put in my battery the self propelled feature stays active and the mower runs away from me! SAFETY HAZARD!!!”

  • A suggestion was made for having more speed options for the drive motor so it can match different walking speeds. (7 reviews)

    • “Ability to have the drive motor go slower, a wider range of speeds”

    • “The "throttle" is great, lowest setting an easy medium pace for me in tougher areas of yard. Then I can adjust faster for flat and easy areas.”

    • “Piling onto the awkwardness of the drive, the top speed is pretty slow. I admit I walk fast, but I think for even casual walkers it'd still be too slow.”

    • “it has different propel speeds for going faster in straight lines or slower around stuff or in smaller areas.”

    • “the only negative I have so far is that the top-end of the self propelled speed is just barely fast enough for me”

    • “I wish the GW self propelled max speed was closer to the Ego’s speed. The GW on fast is like a leisurely walk and the Ego on fast is a brisk walk...some say too fast.”

    • “There is a speed control that gives you a wide range of speeds for the self-propelled function so you have great control over the speed of the cut.”

Bottom Line

Tackle your lawn with the Greenworks MO80L510 mower, a no-hassle, electric powerhouse that cuts grass with ease.

Some users find the self-propel tricky to activate, but overall, it's a solid, eco-friendly choice for yard care.
