Greenworks Pro 60V MO60L424 21-Inch Self-Propelled Lawn Mower Review

The MO60L424 is a 60V brushless, 21-inch, rear-wheel-drive walk-behind mower sold as a kit with two 60V 4.0Ah batteries and a dual-port charger. The deck is stamped steel, the drive is adjustable and variable-speed, and the cutting system offers four modes: mulch, bag, side discharge and a turbo setting for leaf pickup.

The box holds the mower, two 4.0Ah batteries, the dual-port charger and auto switchover.

The mower switches between packs on its own, and a gauge on the handle shows which one is live.

Four cutting modes cover the year: mulch for routine cuts, bag when you want the clippings gone, side discharge for speed, and turbo for leaves. The high-lift blade in the box lets you pick between a cleaner finish and longer runtime.

On grass that is cut regularly, the finish is clean and even. Buyers on Amazon most often praise performance, ease of use and quiet operation, and one buyer notes it handles thick damp grass well.

The drive and controls are simple: rear-wheel drive with a variable-speed lever, separate blade and drive controls, push-button start, and one lever for all seven height positions.

The LED headlights are genuinely useful for dusk mowing, the EZ Fold handles let the mower stand vertically in a small footprint, and the four-year warranty covers the tool and the batteries.

Buyers on Amazon are divided on battery life: some praise the two packs lasting over 60 minutes, others report they don't last long.

You have to nudge the mower forward to free them before reversing.

Buyers on Amazon are split on weight, with some finding it extremely light and others saying it is heavier than expected.

The mower bogs in tall or wet grass.

The large majority of ratings are four or five stars, so most units work, but buy where returns are easy and register the batteries for the warranty.

The 60V packs do not fit the brand's other voltage lines, and there is no adapter, so buying in means committing to this line.

The cutting width is 20.28 inches on a 21-inch deck.

Seven cutting heights from 1.3 to 4.0 inches, changed with a single lever, cover everything from a short summer cut to a taller fall trim. The brushless motor runs at 2,800 RPM in standard mode and 3,200 RPM in turbo.

At 65 lb assembled, the mower is stable on the lawn but heavy to lift and turn. The two 60V 4.0Ah packs give 60+ minutes combined and up to 3/4 acre of coverage per charge.

The stamped steel deck resists knocks better than plastic. The EZ Fold handles collapse for vertical storage, and the warranty runs four years on the tool and four years on the batteries.

On noise, the mower runs 60% lower than gas models, which reads as noticeably quieter than a gas mower.

The decision rule is simple. If your lawn is a quarter to half acre and you mow on a regular schedule, one charge of both packs covers it; if it is larger, or the grass is tall or wet, plan on a mid-job recharge or a third battery. The 3/4-acre coverage figure is a best case on flat, dry, regularly cut grass.

The dual-port charger's 40-minute-per-pack rate means a third battery can keep you cutting almost continuously.

Rear-wheel drive puts the power at the wheels with the most traction, which helps on slight slopes and in thicker grass. The variable-speed lever runs from slow to fast; the top end is brisk and the control is sensitive there.

At 65 lb, turning at the end of each pass takes some effort. The EZ Fold handles collapse so the mower stores vertically in a small footprint.

Two 4.0Ah packs power the mower, with automatic switchover and a handle gauge showing which pack is in use. The dual-port charger fills both in about 80 minutes, and you can also charge one at a time.

The mower runs on a single battery if you want to, but the full runtime figure needs both. The packs do not fit the brand's other voltage lines and there is no adapter.

Two batteries, a dual-port charger, an extra high-lift blade and a four-year battery warranty are what make this a strong package rather than a bare-bones one.
