The Greenworks 40V 17 inch self-propelled cordless lawn mower (MO40B411) provides strong grass cutting capabilities in a lightweight package. Operating on a 40V battery that Greenworks claims can power through 6,000 square meters on a single charge, this mower has features like the push button start and 10 cutting height options for conveniently trimming short to tall grass heights. Its 17 inch cutting deck is suitable for small to medium yards, and the dual-lever system for operating the front-wheel self-propelled power should make mowing simpler on inclined terrain.

Design & Build Quality

The Greenworks MO40B411 40V 17 inch cordless lawn mower is built with quality materials for durability and sturdiness. The deck is made of durable steel that can withstand the regular wear and tear from mowing session after mowing session.

The steel frame also lends sturdiness to the overall build of the mower. Users mention that the mower feels solidly put together, with no flimsiness or weak points in the construction. The wheels are durable plastic and provide good traction on most lawn terrains.

Overall, the materials like steel and plastic are chosen to withstand outdoor use and provide lasting performance mow after mow. While not as rugged as commercial mowers, homeowners find the build quality reliable for typical residential mowing needs.

Cutting Deck

The Greenworks 17-inch electric mower has a 17" swath cutting deck. This ensures you can cut more grass in a single pass, helping you finish mowing faster. The mower's cutting height can be adjusted between 1.25 - 3.5 inches using a single lever, allowing you to tailor the height to your lawn's needs. Setting to a higher height is great for maintaining longer grass, while adjusting to a lower setting will give an exquisitely manicured finish to already well-kept lawns. Overall, the 17" wide adjustable cutting deck provides versatility and efficiency for different lawn conditions.

Motor & Cutting Performance

The Electric toothbrush model features a 500W (2.0 HP equivalent) brushless motor that delivers ample power for residential mowing needs. Despite the lower voltage compared to gas mowers, the optimized gear drive system provides equivalent cutting torque to many gas mowers.

Users report the mower handles thick grass very well thanks to the durable steel blade that spins at up to 3,800 RPM. The 17-inch wide deck allows for a nice 21-inch cutting path to quickly mow small to medium sized yards efficiently. The cutting height is adjustable between 1.5 to 3.5 inches, making it easy to maintain lawn health.

Overall, owners are impressed by the MO40B411's raw cutting power from the high efficiency motor as well as the quality cut from its sharp, well-designed blade. It reliably powers through yard work quickly while still fitting into tight spaces.

Battery & Run Time

The Greenworks MO40B411 gets its power from a 40V, 4Ah Lithium-ion battery. This battery offers a solid runtime per charge of around 45 minutes when tested in normal grass cutting conditions, though the runtime may vary slightly depending on your lawn conditions and grass thickness.

Users report the battery takes about 2 hours to fully charge. The mower comes bundled with one 4Ah battery, which keeps the upfront purchase price a bit lower if you have just a small yard. But you may want to consider picking up an extra battery or upgrading to the larger 5Ah unit if you have a bigger lawn, as the increased run time will save you time with less frequent swapping or recharging.

Some nice features of the battery system:

• The battery powers an LED display showing the remaining charge percentage, allowing you to easily monitor charge status while working.

• The battery pack is interchangeable with other Greenworks 40V tools like string trimmers, chainsaws, leaf blowers etc. So the battery offers some versatility if you own other compatible Greenworks products.

Overall, the 4Ah Lithium-Ion battery provides adequate run time for small to mid-sized yards per charge. Upgrading to the larger optional 5Ah battery or purchasing an extra battery pack can benefit those with bigger lawns.

Noise Level

The Greenworks lawn mower is surprisingly quiet thanks to its brushless motor. Most electric lawn mowers produce around 80-85 decibels of sound while cutting grass. But this mower outputs less than 75 decibels while operating.

That's much quieter than a gas-powered mower that puts out around 90 decibels of noise during use. The difference is quite noticeable. You can easily carry on a conversation while using this lawn mower.

The lower operational noise level means less hearing damage while mowing. It also allows using the mower early in the morning or later in the evening without disturbing neighbors. If noise is a concern for your lawn mowing needs, the Greenworks battery mower is an excellent quiet choice.

Safety Features

The Greenworks MO40B411 electric lawn mower has some important safety features designed to protect the user.

The main safety feature is that there is a safety switch that must be depressed during use. This ensures that if you let go of the handle, the mower blade will automatically turn off. It prevents accidental starts and stops the blade if you trip and fall while mowing.

There is also a key lockout button that disabled the button start to prevent accidental starts. This prevents children or others from starting the mower without pressing the safety switch.

The mower also has a brake that stops the blade after releasing the safety switch or key. This provides an additional layer of protection to quickly stop the fast spinning blades to prevent injuries from accidental contact with the sharp blade. Overall, the Greenworks mower has put a good emphasis on safety with these features.

Ease of Use

The Greenworks 40V electric lawn mower is straightforward and convenient to use thanks to its well-designed controls and excellent maneuverability.

The dual lever height adjustment makes it simple to set the mowing height between 1-1/4" to 3-3/4" to suit your needs and preferences. Adjusting the cutting height is smooth and easy.

The 40V 4Ah battery clicks in and out of the mower cleanly for quick battery swaps when needed. The push button start brings the mower to life instantly.

The handle design provides plenty of room for tall users and folds away nicely for compact storage. Weighing in at 52 lbs, the mower is lightweight enough to move around the yard and maneuver in tight spaces easily.

The dual 10" rear wheels and 7" front wheels roll smoothly across lawns. Reviewers praise the Greenworks mower’s excellent maneuverability thanks to its balanced weight distribution and smooth rolling wheels. The rear-wheel drive gives it good traction and allows the mower to handle rough, uneven terrain well.

Overall, the simple controls, lightweight body, smooth rolling wheels and rear wheel drive gives the Greenworks electric mower stellar ease of use and maneuverability.

Affordable & Competitive Pricing

The Greenworks MO40B411 17" cordless lawn mower has an MSRP of $399. This puts it at the higher end of electric mowers in its class, but it's still an affordable option compared to gas-powered mowers. Most battery-powered models range from $200-500 depending on deck size, battery voltage, and features.

When you compare the total cost of ownership to a gas mower, the Greenworks starts to look even more competitive. With an electric mower like this, there's no need to constantly buy gas, oil, air filters, spark plugs, blade sharpenings, or tune ups. The only ongoing costs are battery replacements every 3-5 years. Considering the eco-friendly performance and low maintenance of the Greenworks, its price tag offers good overall value.

It's also worth noting that other 40V Greenworks mowers with similar power and runtime ratings cost $50-100 more. So while this particular model sits at the premium end, it's priced appropriately for what it delivers. When weighing the price and benefits, the Greenworks MO40B411 represents a solid mid-range electric mower option that doesn't break the bank.
