Greenworks 80V Self-Propelled Lawn Mower: Specs and Guide

The Greenworks 80V self-propelled lawn mower is a 21-inch, brushless, battery-powered walk-behind mower that mulches, bags and side-discharges, with variable-speed drive and a fold-flat handle. With the 4.0Ah battery, Greenworks lists up to about 45 minutes of runtime, which suits small to medium lawns.

Greenworks sells several versions under different model numbers and battery bundles (for example MO80L410 in the US and MO80L06 in Canada). The specs below come from Greenworks’ listing for the 21-inch brushless self-propelled model with a 4.0Ah battery; check the exact model number on the box or listing you are buying.

Specs vary slightly between model numbers and regions. Warranty terms also differ by country, so read the warranty on the listing for your model.

Who Should Buy a Greenworks 80V Self-Propelled Mower?

Good fit if you:

• Mow a small to medium lawn and want to skip gas, oil and pull-starts.
• Have gentle slopes where self-propel saves effort.
• Already own Greenworks 80V tools, or plan to, and want shared batteries.
• Have limited garage space and like vertical storage.

Look elsewhere if you:

• Have well over half an acre and don’t want to buy a second battery.
• Mow steep slopes (Greenworks Canada advises against slopes over 15 degrees).
• Want a lighter mower to lift into a car; at about 77 lb, it is heavy for a battery mower.

How to Start and Use It

1. Slide the charged battery into the battery compartment and close the cover.
2. Set the cutting height with the single lever. Don’t cut more than a third of the grass height at once.
3. Choose mulch, bag or side discharge with the mulch plug or bag fitted.
4. Press the safety start button, then pull the bail bar to the handle to start the blade.
5. Use the speed control to set the drive pace. Engage turbo only for thick grass.
6. Release the bail bar to stop, and remove the battery before clearing clogs or turning the mower over.

Getting the Most Runtime

• Mow when the grass is dry.
• Raise the deck for overgrown grass, then lower it on a second pass.
• Keep the blade sharp; a dull blade drains the battery faster.
• Use turbo only when needed.
• Store batteries indoors, away from freezing temperatures and direct heat.

Pros and Limitations

Pros: no gas or engine maintenance; quiet compared with gas mowers; 3-in-1 deck; folds for vertical storage; battery shared with other Greenworks 80V tools.

Limitations: runtime limits on large lawns; heavy for a battery mower; specs and bundles vary by model number, which makes shopping confusing.

Safety Notes

• Wear sturdy shoes and eye protection, and clear sticks and stones first.
• Keep children and pets away while mowing.
• Always remove the battery before touching the blade or cleaning the deck.
• Don’t mow wet grass; the IPX-4 rating is for splashes, not for wet mowing.

FAQ

How long does the Greenworks 80V self-propelled mower run on one battery?

Greenworks lists up to about 45 minutes with the 4.0Ah battery on its 21-inch brushless self-propelled model. Thick, tall or wet grass and turbo mode shorten that.

How big a lawn can a Greenworks 80V mower handle?

Greenworks does not give an official area figure for this model. Many owners report finishing roughly a quarter to half an acre per charge with the 4.0Ah battery; a second battery helps on larger lawns.

Can the Greenworks 80V mower mulch, bag and side discharge?

Yes. The 21-inch self-propelled models use a 3-in-1 deck for mulching, rear bagging and side discharge.

Can I use the Greenworks 80V mower on slopes?

Greenworks Canada advises against using it on slopes steeper than 15 degrees. Mow across slopes, not up and down, and never on wet grass.

Do other Greenworks 80V batteries fit the mower?

Yes. The mower uses Greenworks 80V batteries, which also power the brand’s other 80V tools such as trimmers, blowers and chainsaws.
