Greenworks Pro MO60L427 Self-Propelled Lawn Mower Review

The mower's strongest argument is how much grass it covers per pass. A 25-inch deck with two 12.5-inch counter-rotating blades cuts a wide swath, and two smaller blades spinning on a wide deck suit a battery platform: there is less rotational mass to keep turning than with one long blade, and the overlapping paths leave no ridge down the middle of the cut.

Two batteries that hand over on their own

The mower runs on one pack and switches to the second automatically when the first runs down, and it will also run on a single battery. Two 4.0Ah 60V batteries and a dual-port rapid charger ship in the box, so you can mow on one pack while the other charges.

Rear-wheel drive with variable speed

Rear-wheel drive puts the pull where the weight sits, which is what gives traction on slopes. The drive and the blade run on separate motors, so you can engage the self-propel with the blades off and wheel the machine around the yard without cutting anything.

Cut quality and mulching

The dual-blade design shreds grass finer than single-blade mowers, and the blades adjust power automatically for tall, wet or thick grass. That automatic adjustment is the feature that keeps the motor from bogging down when the grass gets ahead of you.

Quiet running and lights for low light

High-intensity lights let you mow in the evening or early morning, and the machine runs quietly compared with a gas mower. Buyers on Amazon most often praise its performance, and cutting performance, power, ease of use and noise level all draw mostly positive comments.

Handling, storage and warranty

Rust-resistant aluminum handles and EZ-fold vertical storage let the mower stand on end and take up little floor space in a garage or shed. The warranty covers the tool for 4 years and the battery for 4 years, which is unusually strong coverage on the pack, the part that wears out first. The mower also carries Popular Mechanics' 2021 Best Cordless Mower award.

The mower mulches and rear-bags, and that is all. There is no side discharge, which matters if you side-discharge today and want to keep doing it.

Weight you feel when you lift it

At 67.2 lb, the machine is heavy. The self-propel helps on the ground, not in the air, so plan on a ramp or a second person for loading.

Runtime is the mixed bag

The mower is rated for up to 80 minutes of runtime, but some buyers on Amazon report individual batteries lasting about 45 minutes each, and battery life is the most divided theme in the feedback. Plan for the lower end on thick grass, and keep the second pack charged.

What buyers are divided on

Sturdiness splits opinion: some buyers find the mower well built, while others report breakage. Value splits the same way, with some considering it worth the money and others feeling it is overpriced.

Batteries that stay on one platform

The 60V packs belong to this voltage family and are not interchangeable with other voltage families, so the batteries you already own at another voltage will not run this mower.

Wet grass and gate width

The blades are built to handle wet grass, but mowing wet is hard on any battery mower and clumps the clippings, so it pays to wait for a dry stretch. The deck is 25 inches and the machine is about 27.6 inches wide overall, so measure your gate before you buy.

Three widths decide whether this mower suits your yard, and they are not the same number. The deck is 25 inches, the cutting width is 23.96 inches, and the machine is 27.56 inches wide overall. The deck is the shell, the cutting width is the grass actually cut, and the overall width is what has to clear a gate, a shed door or a path between beds.

The variable speed runs from 3.5 to 4.5 MPH. The dual-port charger brings both packs to full in about 80 minutes. The cutting height adjusts.
