Design & Build Quality

The EGO Power+ LM2135SP lawn mower features an all-metal construction with aluminum alloy deck. This makes it lighter yet more durable than cheaper plastic decks. The materials and build quality allow it to stand up well to rugged outdoor use without succumbing to dents, cracks or rust over time.

Reviewers note that the mower feels very sturdy and solid when pushing it around the yard. All of the parts from the handlebar height adjust lever to the wheels appear sturdy and built to last. Even after years of use, owners comment that it still runs and looks like new thanks to the quality construction.

The materials seem capable of withstanding yard hazards like sticks or stones without compromising performance. Overall the metal design lends confidence that this mower can hold up season after season without any durability issues. It's a testament to EGO's reputation for making equipment meant to endure real world lawn conditions.

Cutting Deck

The EGO Power+ 21-inch electric mower comes equipped with a durable steel cutting deck that provides a wide 21-inch cutting path to help you finish mowing faster. The 3-in-1 cutting deck allows you to mulch, bag, or discharge grass clippings out the side for flexible mowing.

The deck height is adjustable between 1.5 to 4 inches in .5 inch increments, allowing you to cut your grass at just the right height for your lawn type and season. Seven cutting height positions allow you to customize the cut to your needs.

Reviewers praise the excellent cutting performance of the mower. The dual-blade cutting system paired with the Power+ brushless motor cuts grass cleanly and efficiently on the first pass. Many users mention the quality cut comparable to gas mowers. The 21-inch width helps you get the job done quickly while the adjustable heights ensure a precision cut every time.

Drive System

The EGO Power+ electric lawn mowers feature a self-propelled rear-wheel drive system for effortless maneuvering. The variable speed control allows you to adjust the mower speed from 0-3.1 mph to match your preferred walking pace. At the highest speed setting, the mower keeps up with a steady walking pace to reduce fatigue during extended mowing sessions.

The rear-wheel drive allows for excellent maneuverability and tight turns around landscaping beds or other obstacles. The mower can make zero-turn maneuvers thanks to the independent operation of the rear wheels. This high degree of maneuverability makes mowing efficient around trees, fountains, or other tight spots in the yard.

The rear-drive wheels also provide good traction and minimize wheel spin, even in damp grass. With no transmission belts or gears, the direct-drive electric motor provides a smooth, constant power flow to the rear wheels for a seamless mowing experience on flat or hilly terrain. Overall, the rear-wheel drive system enhances control and allows the mower to glide effortlessly around the yard.

Battery & Charging

The EGO Power+ LM2135SP uses a high-capacity 56V ARC LithiumTM battery that provides enough power for up to 45 minutes of continuous mowing time per charge. The 5.0Ah battery is removable and takes just 30-40 minutes to reach a full charge when using the included rapid charger.

The lithium battery holds its charge much better compared to older lead-acid batteries used on some electric mowers. This means you can mow on intermittent schedules and the battery will still have adequate charge when you need it. The included rapid charger utilizes fast charging technology to get the battery back up to full power quickly. Overall, the 56V ARC LithiumTM battery and rapid charger provide ample runtime for small/medium sized lawns and quick recharging convenience.

Noise Level

One of the key benefits of electric mowers like the EGO Power+ is their quiet operation compared to gas-powered mowers. This makes the EGO a great option if you want to mow early in the morning or late in the evening without disturbing neighbors.

Electric mowers like the EGO operate much more quietly than gas mowers for a few reasons. First, they don't have loud combustion engines that require air intake and exhaust. Second, their motors and fans operate very smoothly and efficiently, minimizing mechanical noise. Finally, their noise output is further dampened by the overall chassis and housing design.

Users report the EGO Power+ operates at around 60-70 decibels. This is comparable to the noise level of a normal conversation. By comparison, gas mowers often operate in the range of 90-100 decibels which is significantly louder. The quiet operation of the EGO makes it easy to hold a conversation while mowing.

The quietness of electric mowers like the EGO Power+ make them ideal choices if you want to maintain lawn care while minimizing noise pollution. Gas mowers can often be heard from several houses away while the EGO allows you to mow without disturbing your neighbors. Overall, the quiet operation is a major advantage over gas-powered options.

Safety Features

Safety is a top priority for any lawn mower, especially one this powerful. The EGO Power+ LM2135SP has several important safety features to protect the user.

First, there is an emergency stop button that brings the mower blade to an immediate halt. This allows you to quickly stop the blade if any objects or people unexpectedly enter the mowing path. The emergency stop switch is large and red, making it easy to identify and activate.

Additionally, the mower has an electric blade brake that engages as soon as the operator releases the drive lever. This instantly stops the blade from spinning, preventing accidental contact with the sharp edges. The blade brake provides peace of mind and reduces the risk of injuries.

Together, the emergency stop and blade brake give users multiple ways to safely deactivate the mower blade. These safety features allow the LM2135SP to pack professional power while keeping operation safe even for homeowners new to using this type of mower.

Ease of Use

The EGO Power+ LM2135SP is very easy and intuitive to use. The controls are straightforward with a safety key that must be inserted, a power button, and a single speed self-propel control lever. The speed is variable based on how far you push the lever.

The mower handles well on flat terrain and small hills. It is lightweight at only 56 pounds but has two 7-inch rear wheels that provide stability. Maneuvering the mower is easy with the rear wheel drive. The mower also has a tight 20-inch turning radius allowing you to easily mow around landscaping and trees.

Maintenance on the mower is minimal. There is no oil to change or air filter to clean. Simply washing the mower deck periodically and following other routine maintenance in the owner's manual is all that is required. The mower blades can also be replaced when needed without any tools. Overall, the mower is designed to be low maintenance.

Price

The EGO Power+ LM2135SP 21-Inch Self-Propelled Mower has an MSRP of $599, which puts it at the higher end of electric lawn mowers. However, it's a premium model with excellent power and runtime, so the price reflects the quality.

When you consider the lifetime cost of a gas mower versus electric, the EGO starts to look like good value for money. There are no gas, oil or engine maintenance costs. The 5Ah battery is estimated to deliver up to 45 minutes of runtime and can be charged in as little as 30 minutes. That's enough to mow up to 1/3 of an acre on a single charge.

Additional 2.5Ah and 7.5Ah battery options are available for purchase separately, so you can extend the runtime as needed. At around $149 and $349 respectively, the extra batteries still work out cheaper over time than continually paying for gas and maintenance.

For the performance, features and convenience offered, the EGO Power+ 21-Inch Self-Propelled Mower represents an excellent investment for homeowners who want a high quality electric mower with zero emissions and minimal noise. The price tag may seem high, but you get what you pay for in terms of power, efficiency and longevity.
