EGO POWER+ LM2101 21-inch Push Mower review

The EGO LM2101 is a 21-inch battery mower for someone who wants to push rather than engage a powered drive. The reviewed kit pairs the mower with one 5.0 Ah 56V ARC Lithium battery and a Rapid Charger. It uses the LM2100 push platform and has three ways to manage clippings, but it is not the same machine as EGO’s later Select Cut push mower: the exact LM2101 page does not identify a multi-blade system.

A straightforward push arrangement

With LM2101, the operator provides all forward motion. That is the key choice, not a minor trim-level distinction. It suits a level or gently varied lawn where the user is comfortable steering and pushing a 21-inch mower around turns, edges and obstacles. There is no self-propel control to set, but there is also no powered help when the grass is thick or a route feels tiring. If you need the mower to assist with forward travel, compare the LM2102SP or a later 600-series model such as the LM2114SP.

The battery avoids gasoline storage and pull-starting. EGO says the 56V system is compatible with its other 56V ARC Lithium tools, which may matter to an existing system owner. Compatibility is not the same as a battery being included, though: this assessment is specifically about kit LM2101 and its supplied 5.0 Ah pack and Rapid Charger. The bare-tool configuration is the separately assessed LM2100; its page lists no battery or charger.

Cutting choices and access

The mower has a 21-inch deck, six cutting-height positions from 1.5 to 4 inches, and one-handed height adjustment. EGO lists mulching, bagging and side discharge; the linked manual describes a two-bushel collection bag, a mulch insert and a side-discharge chute. The insert must be removed for bagging and installed for mulching. Think about where clippings should go before starting: bagging means emptying and handling a full bag; side discharge leaves the clippings on the lawn; mulching is sensitive to grass condition and the amount removed in a pass.

A 21-inch cut can reduce passes compared with narrower walk-behinds, but the published cut width is not a measurement of the whole machine. Check gates, corners, shed doors and the folded handle against the mower’s physical size. The manual explains that the handle can be placed in storage, bag-access and three operating positions; plan a dry storage spot with enough room for both the body and handle movement. The exact product image is a manufacturer kit rendering, not a photograph of a tested unit, and it should not be used to estimate actual dimensions.

Battery claims need context

EGO advertises up to 45 minutes from a 5.0 Ah pack. In the linked manual’s table for the related LM2100 base model, estimated running time with that pack is 45 minutes at light load, 30 at medium load and 20 at heavy load. The manual explicitly says grass species, density and moisture change the result. Those are manufacturer estimates, not a promise about lawn area or a measured runtime from this review. Dense, tall or wet growth can force slower travel, a higher cut setting or a second pass.

For a more useful estimate, note how much work remains after a normal charge in your own conditions and decide whether an additional compatible battery would be part of your routine. A spare pack changes the number of available sessions; it does not turn LM2101 into a two-port mower or change its push-only drive.

Manual and care limits

EGO links a 160-page operator manual whose cover lists LM2100 and LM2100SP platform codes plus -FC forms, rather than the kit code LM2101. The exact US product page bridges the LM2101 kit to the LM2100 push platform, so the manual is useful family guidance, but check the instructions supplied with the particular mower. The manual calls for no mowing on slopes over 15 degrees, warns against wet grass, and says to stop the blade, wait for it to stop, then remove the battery before clearing, cleaning or changing the bag, mulch insert or discharge chute. It says not to wash the mower with a hose and warns against getting water into the motor or electrical connections. A weather-resistance claim is not permission to mow in rain or spray the underside.

Who should shortlist the LM2101?

Choose this package when push-only operation is acceptable, a 21-inch deck fits the route, and the 5.0 Ah battery and Rapid Charger are the kit contents you want. It is less suitable if powered drive is essential, if your grass routine regularly involves heavy loads, or if you require a particular blade to be confirmed in the carton. EGO’s product page describes bagging as a mower mode but does not establish that a separate high-lift blade is included, so an exact included-blade requirement should remain unmet unless the seller confirms it.

LM2101 is a simpler package alternative to a self-propelled mower, not a universal answer for every yard. Compare the LM2100 if you own the battery and want the mower-only code, the LM2135 if EGO Select Cut is the important feature, LM2114 if you want a different push kit with a 6.0 Ah battery, and LM2102SP if self-propelled travel matters. Confirm the exact SKU and carton contents before buying.
