Design

The BLACK+DECKER CM2043C is a sleek, modern-looking cordless lawn mower with a 20-inch deck size. It weighs approximately 58 pounds, making it lightweight for an electric mower yet still substantial enough to cut efficiently. The silver and black color scheme gives the mower a high-quality look suitable for yards of any size.

The motor housing and handle design is built for easy maneuverability around trees, landscaping, and other obstacles. At 16 x 21 x 38 inches (LxWxH), the mower can fit through tight spaces where required. A single removable 10-inch rear wheel supplements the 7-inch front wheels, providing a well-balanced profile whether cutting across flats or slopes.

The integrated, foldable handle makes storage a breeze by reducing the mower's footprint. Simply remove the grass catch bag and push the safe start button to reduce handle height. The durable molded deck and rust-resistant blades ensure the mower looks good season after season.

Overall, the thoughtful engineering provides compact storage without sacrificing performance or ergonomics - an ideal combination for home use.

Cutting Deck

The BLACK+DECKER CM2043C electric lawn mower features a 20-inch cutting deck that provides ample cutting width to tackle both small and medium-sized yards. It is constructed from durable steel that can withstand regular wear-and-tear from yardwork.

As part of the design, the cutting deck is adjustable in 6 height positions from 1.5 inches up to 4 inches. This provides flexibility to adapt the cut for different grass length and seasonal conditions. Setting the right cut height helps maintain healthy grass and achieve an even, consistent cut.

The steel construction and adjustable heights make the CM2043C well-equipped for residential mowing needs and grass conditions. The 20-inch width strikes a nice balance for maneuverability and sufficient coverage to get the job done without excessive back-and-forth passes.

Motor Power

The BLACK+DECKER CM2043C lawn mower has a powerful 40V brushless electric motor that delivers gas-like power without fumes, pull cords or loud noise. The electric motor is powered by a 40V MAX 5.0Ah lithium ion battery that provides enough battery life to mow up to 12,500 sq ft on a single charge.

The 40V battery allows the mower motor to spin the 20-inch steel blade at up to 3,750 RPM for excellent cutting performance on grass up to 4-inches in height. The high-efficiency brushless design also maximizes torque, runtime and durability while minimizing noise and maintenance.

Overall, the 40V lithium ion battery provides plenty of sustained power and range for efficiently mowing medium to large sized yards on a single charge. And with no spark plugs, air filters or oil changes, the electric motor requires much less maintenance over the mower's lifetime.

Battery

The BLACK+DECKER CM2043C features a 40V 3.0Ah lithium-ion battery. This battery packs significantly more voltage and power compared to typical 18-24V batteries found in entry-level electric mowers. Many homeowners find the 40V configuration strong enough for even mid-tier mowing needs, eliminating the dropouts and power slowdowns sometimes seen with lower voltage designs.

The 3.0Ah rating denotes the battery capacity. A higher Ah number corresponds to a longer run time before needing to be recharged. For reference, a standard 3.0Ah 40V battery is sufficient for about 25 to 30 minutes of total mowing duration. The CM2043C also supports an optional 5.0Ah battery which doubles the capacity for a potential 45 to 60 minutes of run time.

Overall, the lithium-ion technology provides good stability and value, offering enough juice to tackle typical residential lawns without needing constant mid-mow recharging. The charge cycle is also fast - around 1.5 to 2 hours from empty to full.

Additional Features

The CM2043C comes with several handy features to improve the mowing experience. The dual lever height adjustment makes it easy to choose from 5 different cutting height positions ranging from 1-1/4 to 3-3/4 inches. Simply adjust a lever on each wheel.

The thick, durable polymer handles provide a sturdy grip when pushing the mower. The handles fold down for compact storage as well.

An included rear bag holds up to 18 gallons of clippings and grass, minimizing the number of times you need to stop and empty while mowing larger yards. The bag also makes fall cleanup projects easier by containing leaves.

The modular design allows you to easily convert the mower to side discharge or mulching capabilities too. It comes mulching-ready right out of the box.

Performance

The entire performance of the BLACK+DECKER CM2043C is impressive. Its 20 inch deck and variable speed control gives you superior cut quality, and ability to maneuver easily around trees, fences and flowerbeds.

The powerful motor cuts through both thick and dense grass, yet saves on energy usage by not overtaxing the battery. The unique aerodynamic deck design helps collect the cuttings without getting clogged up. This ensures consistent cutting efficiency even in tall grass or damp conditions.

The BLACK+DECKER electric mower is lightweight, and the freely pivoting rear wheels provide excellent maneuverability and dexterity. The easily adjustable height settings allow you to customize the cut for your specific grass type and terrain. With 5 height positions to choose from, the CM2043C mower makes it very simple to attain a manicured appearance for your lawn.

Ease of Use

The BLACK+DECKER CM2043C cordless mower is designed for easy and convenient operation right out of the box. Assembly is straightforward with no tools required; users report only needing 5-10 minutes to get the mower going from unpacking.

The controls are intuitive - there are two large levers used for propulsion speed and power. The propulsion speed is low by default and can be ramped up continuously. The power has two settings: on and off. A single button starts the motor up and is designed to be easy to press with your thumb while gripping the handle.

Maintenance of the mower is simple and hassle-free. The polymer deck design reduces corrosion issues, and it does not require oil changes or spark plug replacement like gas mowers. As a battery operated unit, there is no gas to fill, drain, or go bad over the winter. The only regular maintenance recommended is periodically wiping the cutting deck off and sharpening the blades as needed.

Users note that due to the lightweight design (about 35lb), it is simple to transport, lift into a car trunk, or maneuver around obstacles. The ease of use and maintenance of the BLACK+DECKER CM2043C is one of its top selling points.

• Easy to use: Weighing only 52 pounds, this mower handles well and is easy to push. The ergonomic handle folds down for compact storage, and the 2-in-1 feature allows you to either mulch or bag clippings. Height adjustment is easy with a single lever.

Cons

• Shorter runtime than some gas mowers - The 40V battery lasts around 30-45 minutes per charge, which is less than some gas mowers. You may need to stop to recharge partway through larger yards.

• Heavier than some cordless models - At over 50 pounds, the CM2043C is heavier than some competing cordless mowers which can make maneuverability more difficult.
