EGO POWER+ 21-inch Select Cut Self-Propelled Mower review

The EGO LM2135SP combines a 21-inch walk-behind deck with Touch Drive self-propelled movement. In the reviewed kit, it includes one 7.5 Ah battery and a Rapid Charger. That makes it a different choice from the push-only LM2135 even though both use the Select Cut system and have the same stated deck width.

Touch Drive changes the walking routine

EGO describes Touch Drive as pressure-activated self-propelled movement controlled from the handle, with a dial to change pace. The listed variable speed is 0.9 to 3.1 mph. The mower still needs to be guided and steered by the operator; drive assistance does not turn a walk-behind into a riding mower or let it work unattended. The hands-on control layout may suit repeated walks and lawns where pushing the deck would be tiring, but shoppers who prefer a simple push arrangement should compare the LM2135 instead.

The 21-inch deck occupies a middle ground between narrow access and a wider cut per pass. It remains worth measuring the complete mower and route: gates, sharp turns and storage entrances can be narrower than the mowing area. The product page says the handle folds for compact storage, but it does not make every storage space a fit.

What the exact LM2135SP kit includes

The current EGO configuration list identifies LM2135SP as a kit with a 7.5 Ah 56V ARC Lithium battery and Rapid Charger. It also lists alternate packages: LM2130SP is tool-only, while LM2132SP-2 and LM2134SP-2 bundle two smaller batteries. These codes matter. A picture of the mower does not tell you whether the seller's carton contains one pack, two packs or none.

EGO's product page describes three-in-one mulching, bagging and side discharge, with a two-bushel collection bag. It lists eight cutting-height positions from 1 to 4 inches, one-handed height adjustment, lights, push-button start and IPX4-rated weather resistance. The page says the system includes Mulching, High Lift Bagging and Extended Runtime blades plus the upper blade. If a retailer offers a different kit or suffix, recheck the included items.

Maximum runtime is not a lawn-size promise

EGO states up to 60 minutes with the recommended 7.5 Ah battery. That is the manufacturer's maximum claim under conditions that can differ from your yard. Cutting taller grass, changing the pace, using self-propelled drive, altering cut height or working with a battery in a different state will change the session. There is no reliable conversion from that maximum time to your acres per charge without comparable test conditions. If runtime is the deciding question, compare the battery and operating details and consider whether your yard can be divided into sessions.

The mower is listed as compatible with EGO's 56V ARC Lithium battery system. That is useful if you already own the platform, but it does not mean every battery size is part of this kit or that the maximum runtime will match the included 7.5 Ah figure. EGO lists approximately 60 minutes to charge the recommended battery with the Rapid Charger; charging time and mowing time are separate measures.

How it differs from the related EGO models

The push LM2135 includes the same nominal battery capacity and charger in a package without self-propelled drive. The LM2135SP is a more logical comparison when the walking pace matters, but the manufacturer states a lower maximum runtime for this kit. The LM2156SP adds the Select Cut XP system and an included 10.0 Ah battery; it also lists 8.3 ft-lb maximum torque and up to 75 minutes. These numbers describe distinct manufacturer claims, not a ranking or evidence that one will finish your property.

EGO links a shared 56V mower manual from its product page. Its cover names LM2130SP/LM2130/LM2150SP families rather than the reviewed LM2135SP kit code, so it is platform guidance rather than a fully established exact-SKU manual bridge. Confirm the current instructions for your model code and the supplied battery and attachments before use.

Who it suits and the reasons to keep looking

Shortlist LM2135SP if you want a battery-powered 21-inch mower with self-propelled drive and the 7.5 Ah kit package. It is a clear fit for shoppers who have chosen the EGO battery platform and want the assisted walking mode rather than a bare tool or a push model. Keep looking if a 10 Ah included battery is non-negotiable, if a 22-inch deck minimum rules out this width, or if your yard requires a riding arrangement.

Do not let IPX4 imply that rinsing the mower is an approved cleaning method. The linked manual says not to mow wet grass or slopes greater than 15 degrees. Before cleaning or clearing, remove the battery and wait for the blade to stop; the cleaning page says not to put water on the motor fan and to wipe the mower with a damp cloth. Its cover names LM2130SP/LM2130/LM2150SP families, not LM2135SP, so confirm the current instructions for the exact SKU before relying on them.
