Greenworks MO48L520 Self-Propelled Lawn Mower Review

The mower's strengths are the ones a small-lawn owner feels every week.

Push-button start and no engine upkeep

There is no gas, no oil and no pull cord. You press a button and the brushless motor spins up. Starting on the first try is the most consistent positive in what buyers on Amazon report, and it is the single biggest change for anyone coming from a gas mower that sat all winter.

Variable-speed rear-wheel drive

The drive sits on the rear wheels, which carry the traction, and the speed is variable so you can match your pace to the lawn. Buyers on Amazon single out the self-propel as a plus, and one customer notes it works well on hills.

Light for a self-propelled mower

At 77 lb, it is light for a self-propelled machine. It is still a two-hand lift, not something you carry up a flight of stairs.

Quiet running

It runs 30% quieter than gas.

21-inch steel deck and brushless motor

The deck is steel and the motor is brushless, so there are no brushes to wear and no engine maintenance to schedule. The 20.28-inch cutting width is a standard residential size: quick enough for a small lawn, narrow enough to pass a gate.

Four cutting modes and seven heights

You get mulching, rear bagging, side discharge and a turbo mode for heavy or tall grass and leaves. Cutting height runs from 1 inch to 7 inches across seven positions, changed with a single lever, so adjusting is a one-hand job.

Folds and stands upright

The handle folds and the mower stands vertically, which is a real advantage in a small garage or shed. An LED headlight covers low-light mowing.

Two batteries and a dual-port charger in the box

The kit includes two 24V 5.0Ah batteries and a dual-port rapid charger that tops up both packs. The batteries are part of a 125+ tool platform, so they can do double duty with other tools in the same line. The warranty is 3 years limited.

Self-propel, a brushless motor, two batteries and a dual-port charger in one box are what make this kit worth considering for a small lawn.

Runtime is the headline limit. Average battery life is 45 minutes, and it varies with grass thickness. Buyer feedback on Amazon is split: some say the batteries stay charged long enough, others report they last about 30 minutes. Thick, wet or tall grass, turbo mode, constant self-propel and a low cut height all pull the number down.

The mower runs on a pair of batteries. The dual-port charger handles both.

The recommended lawn size is up to 1/4 acre. Buyers with larger lawns report the mow stretching out or needing a second charge, so size your own yard against that figure before you buy.

At 77 lb the mower is light for a self-propelled machine but still a two-hand lift.

Before buying, check whether the mower has a washout port for hosing out the deck and a blade-brake clutch for controlling the blade separately from the drive. If you plan to bag and empty often, check that point before buying.

Turbo mode and self-propel both draw on the same batteries. Using them constantly shortens the run, and that is the most useful thing to know before your first cut.

The 20.28-inch cutting width is a standard residential size: quick enough for a small lawn, narrow enough to fit through a gate. The 1- to 7-inch range across seven positions covers everything from a close summer trim to a taller cut that protects the grass in heat.

The mower weighs 77 lb and has a folded footprint of about 62 inches long, 22 inches wide and 41 inches high, so check the corner of the shed or garage before buying. The folded size is compact for a self-propelled mower, but it still needs a dedicated spot.

The 45-minute runtime is an average, and grass thickness is the main variable. The next section covers how to stretch it.

The 45-minute runtime is an average, and it varies by grass thickness. Several things you control decide whether you get the full figure or fall short of it.

• A lighter load means less stopping and less power spent pushing clippings into a bag.
• A taller cut takes less power than scalping the lawn.
• Turbo is for tall grass and leaves, not routine mowing.

On yard size, up to 1/4 acre, flat to gently sloped, mowed weekly in mulch mode is comfortable and is the mower's sweet spot. Well over 1/4 acre, steep ground, or tall and wet grass regularly will frustrate you, and a mower built for bigger lawns is the better fit.

One buyer finds the 45-minute figure optimistic in thick grass. The difference is usually the grass and the settings, not the machine.

Mulching is the default best mode for this mower: fine clippings, no bag to empty and better runtime. Bagging works, but the bag fills fast, so it is best for the occasional cleanup or when the grass is long. Side discharge handles tall grass you do not want to mulch, and turbo is a tool for leaves and overgrown patches rather than a setting you leave on.

The self-propel is variable-speed rear-wheel drive. The drive lever and the speed control take a cut or two to get used to, and the single height lever makes changing the cut quick.

Storage is the routine: fold the handle, stand the mower upright, roll it into the corner. The LED headlight covers early or late mowing.

If you want to hose the deck clean rather than clean it by hand, check whether the mower has a washout port before buying.

The steel deck and the brushless motor are the durable core of the machine. The batteries are the story: two 5.0Ah 24V packs and a dual-port rapid charger are included, and the packs work across 125+ tools on the same platform.

For a homeowner already in that ecosystem, the mower is the anchor purchase and the batteries do double duty. For someone starting fresh, this is the moment to decide whether to build around this platform.

The warranty is 3 years limited on the kit.
