Product Features
Two interchangeable, stackable blades let you dial in the cut: mulching blade for finely chopped clippings, high-lift blade for a full bag, or run both for the cleanest finish on thick turf.
A separate drive motor pulls the mower forward from 0.9 to 3.1 mph. Set your pace with the thumb dial and simply walk — hills and long runs stop being a workout.
The 21" deck and high-lift airflow stand grass up before it cuts, so the overgrown first mow of the season comes out even instead of scalped and clumped.
Swap between mulching, the 2.0 bushel bag, and side discharge in seconds. The bag packs evenly to the top so you make fewer trips to the compost pile.
A 56V 7.5Ah ARC Lithium™ battery mows up to 60 minutes on a charge — and the same battery powers every other EGO 56V tool in your garage.
Bright LED headlights let you finish after work, and IPX4 construction means a wet deck or a surprise shower is a non-event.
The handle folds down and the mower stands on end, taking up about the footprint of a trash can. No gas, no oil, nothing to drain before winter.
Technical Specs
Out of the box to first cut in under 10 minutes — unfold the handle, drop in the battery, press the button.
Free shipping on every mower kit. Ships in 2–5 business days from our closest U.S. warehouse.
5-year warranty on the mower and 3 years on the battery and charger, backed by real U.S. support.

My back yard has a long slope that used to wear me out with the gas mower. With the drive set around the middle speed I just walk behind it. Cut quality with both blades stacked is excellent and the bag fills right to the top.

First electric mower after 20 years of gas. No fumes, starts instantly, and the mulching blade turns the clippings into dust. I do about a third of an acre and finish with battery to spare.

Cuts beautifully and the variable speed is perfect. Only knock is the weight when you have to lift it into the truck or turn it around at the end of a row — the self-propel hides it most of the time though.

Ran the high-lift blade alone for bagging in the fall and both blades in spring. The difference in how clean the lawn looks is obvious. Headlights got used more than I expected.

Storage was my biggest worry in a small garage. It folds flat and stands upright next to the shelves. Charging is quick and I never think about gas cans again.

Same power, half the noise, and no maintenance. The drive is smooth and easy to control with one hand.

Mows my whole lot on one 7.5Ah battery with charge left over. Cut is even and the bag is easy to empty.
— JHarris · Feb 12, 2026 · Verified
No complaints about power or the self-propel. In heavy spring growth I do empty the bag a few times.

Went two weeks without mowing and it chewed right through it without bogging down. Impressed.

The self-propel means anyone in the house can mow. That alone was worth the upgrade from the push model.

Feels well made, deck is sturdy, height lever is easy. Slightly heavy but the drive compensates.

Mower is great. I'd recommend stepping up to the kit with the rapid charger if you mow often.

Push a button and go. My shoulder thanks me every single week.

Added the striping kit and the lawn looks like a ballpark. Cut quality with both blades is superb.

Does everything advertised. Took a couple mows to find my preferred speed setting.

I can mow at 7am without waking the neighborhood. Big win in my subdivision.
— Sam T. · Dec 19, 2025 · Verified
Already had EGO trimmer and blower, so the batteries all swap. That's the whole reason I stayed with the platform.
