The mower folds up for easy storage when not in use. With no oil changes or gasoline required, the MTE912 offers a lower maintenance alternative to traditional gas mowers.

The MTE912 aims to provide an easy, eco-friendly mowing experience for homeowners with small to medium sized lawns. Keep reading for more details on the mower's design, features, performance, and pros and cons.

Design

The Black & Decker MTE912 electric lawn mower has a compact, lightweight design that makes it easy to maneuver around the yard. At just 21 pounds, it is one of the lightest electric mowers on the market. Its dimensions are 20 x 13 x 11 inches, giving it a small footprint that can fit into tight spaces.

The mower deck is made from durable plastic that is resistant to rust, chips, and cracks. This keeps the mower looking nice even after years of use. The plastic is reinforced in high-wear areas to prevent sagging.

You'll find easy-grip handles and knobs, allowing you to operate the mower comfortably. Rubberized wheels add traction when rolling across uneven terrain in the yard. Despite its light weight, the sturdy build quality ensures the mower holds up well during mowing sessions.

Cutting Deck

The BLACK+DECKER MTE912 electric lawn mower features a durable 12-inch steel cutting deck that provides ample cutting width to mow small-to-medium sized lawns efficiently. The cutting height is adjustable between 1.5-4 inches using a single lever, making it easy to customize the cut to your needs.

The cutting deck houses a reliable 12-inch steel blade that delivers a clean cut. The blade is designed to provide optimal airflow and clipping circulation within the deck. The ample 12-inch width and sharp steel construction allow the mower to cut through grass cleanly and efficiently.

The metal cutting deck is rugged and meant to stand up against nicks, abrasions and impact while mowing and trimming. The steel construction also aids in noise reduction while operating compared to plastic decks. Overall, the 12-inch cutting deck offers versatile cutting height options and a durable steel blade to take on small-to-medium lawns.

Motor

The motor in this electric lawn mower is powered by a rechargeable 40V lithium ion battery. The motor provides enough power and torque to cut through even thick, wet grass without bogging down. The 12 inch cutting deck allows the mower to maneuver easily around landscaping and flower beds.

One charge of the battery provides enough energy to mow up to 1/4 acre of lawn. Charging the battery fully takes about 4 hours. The battery meter lets you know how much runtime you have left before needing to recharge.

The motor voltage is optimized to provide an ideal balance of power and run time. Lower voltage motors struggle on thicker grass while higher voltages drain the battery more quickly. This Goldilocks "just right" 40V gives you the ability to mow the lawn efficiently without having to stop often to recharge.

The design of the motor aims to provide consistent power and torque regardless of the grass conditions. It has ample current (measured in amps) even for cutting wet or damp grass. The motor electronics protect against power overload, overheating, low voltage, and other faults. This results in a robust, reliable mower you can count on season after season.

Overall, the motor in this electric mower hits the sweet spot between power, efficiency, and longevity. It has enough oomph to tackle any yard chore without being overkill. Many homeowners find the performance comparable to gas mowers without the extra maintenance.

Battery

The MTE912 electric lawn mower comes equipped with a 30V 2 Ah lithium-ion battery that provides enough power to cut up to 1/4 acre on a single charge. The battery voltage is ideal for a mower of this size, offering a good balance of power and runtime.

Lithium-ion batteries are lightweight and hold a charge well, even when not in use. This allows the battery to maintain its capacity over time much better than other battery types.

The battery runtime is sufficient for small to medium yards. You can expect it to run for 30-45 minutes per charge, giving you enough time to mow and trim most suburban lots. The battery charges fully in about 4 hours.

Overall, the 30V lithium-ion battery is well-suited for this electric mower. It delivers ample voltage and capacity for the 12" cutting deck, while still remaining lightweight and easy to maneuver. The fast charging time also allows you to get back to mowing in a short period if you need to recharge during longer jobs.

Additional Features

The BLACK+DECKER MTE912 electric mower has several additional features that add convenience and versatility for home use.

Mulching

The mower has mulching capabilities that allow it to cut grass clippings into tiny pieces and deposits them back into the lawn. This nourishes the grass and soil without leaving clumps of clippings on the lawn. The mulching blade and deck design help create an even mulching effect.

Bagging

There is a 1.2 bushel rear bag included with the mower to collect grass clippings while mowing. The nylon cloth bag can be easily attached and removed as needed. When bagging, the mower converts clippings into fine mulch to reduce the number of times you need to empty the bag.

Side Discharge

For taller grass, the mower can discharge clippings from the side and propel them away from the mowing path. This prevents clumping when cutting high grass. The discharge chute can be easily attached without tools when side discharge is preferred over mulching or bagging.

Ease of Use

The Black & Decker MTE912 electric lawn mower is designed for easy maneuverability and convenience.

Controls

The controls on the MTE912 are simple and intuitive. There is a single button to turn the mower on and off. Once powered on, the mower is ready to go without any pull cords or priming needed. The handle adjusts to two positions - standard and height adjustable - to accommodate users of different heights.

Maneuverability

Weighing only 43 pounds, the MTE912 is lightweight and easy to maneuver. The 12 inch cutting deck allows the mower to get into tight spaces and trim close to obstacles. The compact design makes storage simple, even in limited space.

Noise Level

This electric mower operates quietly at only 68 dB, which is less noise than a standard gas mower. Homeowners will appreciate being able to mow early in the morning or late in the evening without disturbing the neighbors. The quiet performance allows the mower to be used in noise-sensitive environments as well.

Maintenance

Keeping the Black & Decker MTE912 electric mower well-maintained ensures it continues running at peak performance. This mower requires minimal maintenance compared to gas mowers.

Cleaning

The Black & Decker MTE912 has a removable rear bag for catching clippings that can be emptied and rinsed out. The mowing deck should be wiped down after each use to prevent a buildup of grass clippings and debris. It's also recommended to periodically wipe down the mower body and wheels.

Blade Replacement

The blade should be inspected regularly for any nicks or dull edges. Blades usually need replacing after 1-2 seasons of regular use. Replacing the blade helps restore a sharp, even cut. The Black & Decker MTE912 uses a 12" steel blade that can be easily removed and replaced by the owner when needed. The mower comes with an extra blade in the box.

Warranty

The BLACK+DECKER MTE912 electric lawn mower comes with a 2-year limited warranty. The warranty covers defects in materials or workmanship for 2 years from the date of original purchase.

The warranty is valid only for the original purchaser with proof of purchase. It does not cover normal wear and tear, misuse or abuse. The warranty is void if the mower is disassembled or repaired by an unauthorized service center.

The limited warranty covers the cost of replacement parts and labor. Transportation costs to return the product for warranty service are not covered.

Overall, the 2-year limited warranty provides reasonable coverage for defects and workmanship issues. However, the warranty is relatively short compared to higher-end electric mowers which often come with 3-4 year warranties. Make sure to register your mower upon purchase to take full advantage of the warranty terms.
