Greenworks MO40L04 40V 19 inch Electric lawn mower: In-Depth Review and Customer Opinions

The Greenworks 40V 19-inch cordless electric lawn mower offers a high-performance battery-powered alternative to gas mowers. This self-propelled model combines a brushless electric motor with an easy push-button start and quiet operation.

The Greenworks 40V battery platform powers multiple garden tools to provide up to 70 minutes of continuous mowing on a single charge. At just 67 pounds, the 19-inch width allows the mower to maneuver in tight spaces while cutting a decent swath on each pass.

With its cordless convenience and emissions-free operation, the Greenworks 40V mower makes an attractive option for small to mid-sized lawns. Read on for a more in-depth look at the features and performance of this battery-powered lawn mower.

Motor and Cutting Deck

The Greenworks 40V mower uses an efficient brushless motor that provides more torque and a longer lifespan compared to brushed motors. A brushless motor has permanent magnets rather than brushes and a commutator to distribute current. This makes brushless motors quieter, more lightweight, and allows for variable speeds to optimize cutting and conserve battery life.

The 40V motor on this mower spins the 19 inch steel cutting deck up to 5000 RPM to cut grass cleanly and efficiently. The steel deck is durable and resists corrosion. The 19 inch width allows the mower to cut a decent sized swath in one pass. The 2-in-1 design means you can either mulch or bag clippings, with a rear bag attachment included. Overall the motor and deck size make this a capable mower for small to mid-sized yards.

Battery and Runtime

The Greenworks MO40L04 mower comes equipped with a 40V 4Ah lithium-ion battery. This battery provides enough power to mow up to 1/2 acre on a single charge.

One of the key benefits of the 40V battery is its long run time. With a fully charged battery, you can expect around 60 minutes of mowing. This allows you to tackle even larger yards without having to stop repeatedly to recharge. The battery takes about 2 hours to fully recharge once drained.

The lithium-ion composition of the battery has several advantages over traditional lead-acid batteries. Lithium-ion holds a charge longer, provides more power, and weighs less than comparable lead-acid batteries. They are also better suited for partial recharges.

Overall, the 40V lithium-ion battery provides excellent runtime for mowing medium to large yards efficiently on a single charge. The long run time and fast recharge make it easy to keep your mower powered up.

Cutting Height and Width

The Greenworks MO40L04 electric mower has a total cutting width of 19 inches, which allows it to cut a decent sized swath in a single pass. This makes it well suited for small to medium yards up to around 1/4 acre in size.

In terms of cutting height, this mower offers adjustable settings between 1-3/8 inches to 3-3/4 inches, in 7 different height positions. This provides the flexibility to cut your grass at the ideal length for the season or your lawn's needs. Raising the deck higher gives your grass longer length for health during hot summer months, while lowering it allows a closer trim for fall.

The dual lever height adjustment makes it simple to change the cutting height. Just move both levers to the same setting to ensure an even cut across the full deck width. The cutting height range works well for most homeowners, although if an extremely short cut under 1 inch is desired, a reel mower would be a better choice. But for typical lawn heights, the Greenworks adjustment range offers ample variability.

Maneuverability

The Greenworks 40V cordless electric lawn mower weighs 52 pounds, making it relatively lightweight and easy to maneuver compared to gas mowers. The rear wheel drive design provides excellent traction and allows you to navigate turns and hills with ease.

The ergonomic handle folds down for compact storage and features cushioned grips for comfort. Adjustable handles make it easy to find the perfect pushing position whether you are short or tall. The intuitive control panel is located on the handle for quick access while mowing.

Overall, the light weight and rear wheel drive enable smooth, effortless maneuvering around landscaping and tight spaces. The thoughtful handle design reduces hand and arm fatigue when mowing for extended periods. If maneuverability is important for your lawn, the Greenworks 40V cordless mower delivers on that front.

Noise Level

The Greenworks 40V 19" electric lawn mower operates at a noise level of 69 decibels. This places it on the quieter end of the spectrum for electric mowers. Most electric mowers generate noise in the range of 60-70 decibels, while gas-powered mowers are typically 95+ decibels.

At 69 decibels, the Greenworks mower produces about the same level of noise as a typical conversation. This makes the mower easy to talk over and less disruptive compared to gas models. The quiet operation is ideal for using the mower early in the morning or late evening without disturbing neighbors. It also reduces noise pollution and makes mowing more pleasant without needing hearing protection.

The brushless motor and blade design contribute to the lower decibel rating. There is no loud gas engine producing noise. Overall, the quiet operation is a major advantage of the Greenworks electric mower over similar gas mowers. It provides a pleasant, peaceful mowing experience.

Safety Features

The Greenworks MO40L04 electric lawn mower has several important safety features to protect the operator. It has an operator presence control, which means the blade will stop spinning within 3 seconds if the operator's hands come off the handles or control bar. This helps prevent accidents if the mower tilts or the operator loses control.

There is also a lock-out switch that must be depressed before the mower will start. This switch disables the start function unless intentionally held down, preventing accidental starts. Once running, taking your hands off the switch will not stop the mower, thanks to the operator presence control. But releasing the switch makes it more difficult for children or others to start the mower without your knowledge.

Both of these safety features work together to stop the spinning blade quickly in an emergency, and prevent unauthorized use. They provide an extra layer of protection while operating the mower.

Ease of Use

The Greenworks lawn mower is very easy to assemble out of the box. All necessary tools are included. The instruction manual provides clear, straightforward steps that one person can complete in around 30 minutes or less.

Starting the mower is simple with just an push button start. The controls are intuitive and easy to operate, even for first time electric mower users. The handle bars fold down for compact storage or transportation.

Maintenance is minimal for the Greenworks mower. There is no oil to change or spark plugs to service like a gas mower. The 40V lithium-ion battery lasts up to 70 minutes on a full charge, avoiding the need to stop and refuel. Lubrication of moving parts may be needed periodically. The mower deck underside where the blade is can be accessed to clear any accumulated clippings. Overall the Greenworks mower provides a low maintenance experience.

Price

The Greenworks 40V 19-inch cordless electric lawn mower has an MSRP of $349. This puts it in the mid-range for cordless electric lawn mowers. Comparable models from other brands like Ego, Ryobi, and Craftsman range from $300-$500 depending on features and battery performance.

At this price point, the Greenworks 40V offers good value for the features and power it provides. The two included 4Ah batteries provide up to 45 minutes of runtime and can power the mower to cut up to 1/4 acre on a single charge. This is sufficient for most small-medium sized residential yards. The 19-inch cutting deck allows you to finish mowing efficiently.

The brushless motor and steel deck construction add durability, which help justify the price. When you consider the reduced maintenance costs and environmental benefits compared to gas mowers, the return on investment can make the Greenworks 40V worth the initial spend. Overall, this model hits the sweet spot between price and performance for a cordless electric lawn mower.
