Ego Power+ LM2100SP Features and Specifications

Ego Power+ LM2100SP is designed as 3-in-1, walk-behind lawn mower and is powered by onboard lithium-ion battery.

Recommended battery size is 7.5 Ah battery, which is able to store impressive 420 Wh of energy and is able to power Ego Power+ LM2100SP for long time - operating time on the single battery charge depends on many things, more on that later.

Also, Ego Power+ BA4200 is 56V 7.5 Ah lithium-ion battery that features battery management system which protects the battery from damage due to the heat, overcharging, over-discharging and similar.

Ego Power+ BA4200 weighs 6.31 pounds (2.86 kg) and comes with 3-year limited warranty, while Ego Power+ LM2100SP lawn mower comes with 5-year limited warranty.

When being powered by 7.5 Ah battery, operating time of the Ego Power+ LM2100SP on the single battery charge is:

- light load: 60+ minutes,

- medium load: 45 minutes,

- heavy load: 30 minutes.

Actual operating time depends on many conditions like density of the grass, species, moisture, if the self-propelled drive system is engaged or not, etc.

As 3-in-1 lawn mower, Ego Power+ LM2100SP features side discharge of grass clippings, can be used for mulching or it can store grass clippings in the large grass collector bag which features capacity of 2.u bushels (70 liters).

Despite having 21 inch (~53.3 cm) cutting deck, Ego Power+ LM2100SP is relatively lightweight unit weighing 62.61 pounds (28.4 kg) without battery pack and ~69 pounds (~31.2 kg) with 7.5 Ah battery.

ego lm2100sp controls

Controls of the unit are rather simple and easily accessible by the user.

Self-propelled feature drain the unit faster, but it may be very helpful during mowing, especially on the uneven terrain (be very careful when mowing on such terrain or on the slopes!) and when mowing is done by elderly people.

Self-propelled feature is not mandatory and many users operate Ego Power+ LM2100SP like ordinary lawn mower and use self-propelled feature before and after actual moving, when it is time to store the unit.

When self-propelled feature is used, speed varies between 1.8 and 3.6 mph (~2.9 and 5.8 km/h).

Note: Engaging lawn mower blade does not automatically starts the self-propelled feature and vise versa, starting self-propelled feature does not automatically starts the mowing blade - these are two independent systems! Ego Power+ LM2100SP is relatively simple unit to assemble, use and maintain, just be sure to thoroughly read the manual that comes with the unit.

Front wheels of the Ego Power+ LM2100SP are 7 inches (~17.8 cm) in diameter and rear wheels are 9 inches (~22.9 cm) in diameter, ensuring good maneuverability on the flat terrain. Self-propelled drive engages only the rear wheels - it is not 4x4 drive (most of the self-propelled walk behind lawn mowers feature drive on the rear axle only).

Note: Ego manufactures two very similar cordless lawn mowers, Ego Power+ LM2100SP (reviewed in this article) and Ego Power+ LM2100 - main difference between these models is that Ego Power+ LM2100SP is self-propelled lawn mower, while Ego Power+ LM2100 is not self-propelled.

For operations in low-light conditions Ego Power+ LM2100SP comes with a pair of strong LED headlights, helping the user to see what is ahead of the unit - just be very careful when mowing in such conditions due to the low visibility in general.

LED headlights are questionable feature on home lawn mowers since mowing in low light conditions is not the safest thing to do. However, during summer heat, it is perhaps safer to mow the lawn early in the morning or late in the evening - safer for the both the user and the cut grass/lawn!

Maximum, no-load blade speed is 2800 rpm, ensuring clean cuts with the sharp blade.

Cutting height is adjustable using single lever, featuring 6 positions: 1 1/2" (41 mm), 2" (51 mm), 2 1/2" (65 mm), 3" (77 mm), 3 1/2" (93 mm) and 4" (107") - be sure to adjust the cutting height to the grass, season, heat, moisture etc.

ego lm2100sp storage

Ego Power+ LM2100SP features foldable handles, allowing the user to store the mower either horizontally or vertically, saving storage space.

Note: Although vertically stored Ego Power+ LM2100SP is rather stable, don't let pets and kids play around it - if pushed with enough force, it can fall down and hurt somebody or damage something. Safety first!


ego lm2100sp mLong Story Short: If you are looking for a cordless lawn mower that features power almost like gas unit, but emit no fumes and is rather quiet during mowing, consider Ego Power+ LM2100SP.

If you don't already have 56V 7.5Ah battery and required battery charger, initial investment is perhaps little bit larger, but in the long run it allows the user to purchase other Ego garden tools without the battery at very affordable prices, saving the money in the long run.

Of course, other batteries may be used as well, but smaller the battery, shorter the running time on the single battery charge. And here is where 2 or more batteries and rapid charger may come very handy.
