Our take
EGO LM2101 is a 21-inch battery mower kit built around the 5.0 Ah ARC Lithium battery and rapid charger. The manufacturer lists six cutting-height settings from 1.5 to 4 inches, a 2-bushel collection bag, and mulching, bagging, and side-discharge options. The LM2100 manual identifies the base mower as having no self-propel system, while EGO's product page maps LM2101 to that 21-inch mower with the battery-and-charger kit. That makes this a wide, included-kit push option beside the self-propelled EGO models already reviewed. EGO's up-to-45-minute figure is a stated maximum with the recommended battery, not a promise for a particular lawn. This is a documentation-based review; we have not tested the mower or verified today's Amazon seller offer.
A buyer seeking a 21-inch battery mower with the battery and rapid charger included, and who is comfortable pushing instead of relying on powered drive..
Look elsewhere if powered forward movement, a narrower deck, or a verified runtime guarantee is essential. The maker's page supports the LM2101 configuration, but it does not establish that a current Amazon result has the same included battery, charger, condition, or warranty. Confirm those details before purchase.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The EGO page names LM2101 as the 21-inch mower configuration with a 5.0 Ah battery and rapid charger included.
- The documented 2-bushel bag and three clipping modes allow a buyer to choose collection, mulching, or side discharge.
- Six height positions span 1.5 to 4 inches, and EGO says the handle folds for compact storage.
What to weigh up
- The LM2100 manual lists no self-propel system, so the operator supplies forward movement across the 21-inch deck.
- The up-to-45-minute runtime is tied to EGO's recommended 5.0 Ah battery and is not a measured estimate for an individual yard.
- EGO's page identifies the maker's kit, but it does not prove the exact contents or condition of this historical Amazon ASIN today.

Full review: how the features affect your choice
What the features mean for you
A battery kit with a specific platform
EGO's configuration table distinguishes the bare LM2100 from LM2101, listing the latter with a 5.0 Ah battery and rapid charger. The mower uses EGO's 56 V ARC Lithium platform, and the manufacturer says its batteries are compatible across EGO outdoor equipment. This is useful when the buyer wants a complete mower package or already owns compatible batteries. It is not proof that every marketplace listing for the model number contains the same kit. Check the seller's exact contents, battery condition, and warranty terms; the old Amazon row's extra-battery wording is not independently verified by the maker page.
Push drive keeps the comparison simple
EGO's LM2100 operator manual lists the self-propel system as absent for that base mower, and the product page presents LM2101 as the same 21-inch mower configuration with a battery and charger. In practical selection terms, this is a push mower: the operator moves it forward. The 21-inch deck is wider than compact 14- to 18-inch choices and matches several full-width alternatives, but width alone does not establish cutting speed or effort. Buyers who need assistance on slopes or long routes should compare it with the reviewed self-propelled EGO LM2102SP or LM2135SP instead of treating battery power as powered drive.
Three clipping choices and a two-bushel bag
The official product specifications list mulching, bagging, and side discharge, and EGO gives the collection bag a 2-bushel capacity. These details offer more documented clipping configurations than a mower whose manual leaves collection options open. They do not establish how often a buyer will empty the bag or which method is best for a particular lawn. Compare the 2-bushel figure with another model's published capacity only when both use the same unit. The seller should confirm that the needed chute, plug, and bag are present in the offered package, especially for a used or renewed listing.
Six height settings cover a documented range
EGO specifies six cutting-height positions from 1.5 to 4 inches and describes a one-handed height adjustment. The lower and upper endpoints make it possible to screen the mower against a hard height requirement without borrowing values from another EGO model. The range does not prescribe a correct setting for every grass type, season, or lawn condition, and the number of positions does not show the spacing between every step. If your decision depends on a particular intermediate height, consult the owner's manual or confirm it with EGO rather than guessing from the endpoints.
Treat the runtime as a conditional maker claim
EGO states up to 45 minutes on a single charge with the recommended 5.0 Ah battery, which is the battery listed for the LM2101 configuration. The phrase 'up to' marks a maximum claim; the page does not establish a guaranteed duration across grass, terrain, blade condition, or operating choices. EGO also says the mower folds for compact storage and gives an approximate 50-minute charge time with the recommended battery and rapid charger. Those figures can help compare documented setups, but buyers should plan around their own conditions and retain the manual for care and charging instructions.
Compare for your needs
Compare EGO LM2102SP if powered forward movement and a 7.5 Ah battery kit matter more than a push-only layout. EGO LM2135SP adds Select Cut and self-propelled drive, while compact WORX WG779 has a 14-inch deck and included batteries for narrower routes.

Before you buy
Does the LM2101 propel itself?
The LM2100 manual lists no self-propel system for the base mower, and EGO maps LM2101 as that 21-inch mower's battery-and-charger configuration. Treat it as push-only; the operator supplies forward movement.
What comes in the LM2101 kit?
EGO's configuration table lists a 5.0 Ah battery and rapid charger with LM2101. That confirms the manufacturer configuration, not the condition or contents of a current Amazon offer, so verify the seller's exact package.
How long can it run on one charge?
EGO states up to 45 minutes with the recommended 5.0 Ah battery. This is a conditional manufacturer maximum, not a measured guarantee for a specific yard or mowing condition.

The decision
LM2101 is a well-documented 21-inch push-kit option with a battery, rapid charger, 2-bushel bag, and three clipping modes. Its drive style and conditional runtime should be weighed against your route, and the exact seller package still needs verification.
