EGO has two 21-inch deck 56-volt lithium-ion cordless battery mowers that are quite popular and share a number of similarities: the LM2101 and the LM2102SP. The major differences between the two are that the LM2102SP is self-propelled has a larger-capacity 7.5Ah battery and it costs $100 more. For the purposes of this review we are going to focus on the features they share in common.
The reviewer at The Wirecutter said This Honda is in a class of its own. He was impressed with how the mower cut grass into smaller pieces with its double-blade design. And he found the Versamow system incredibly helpful. However the reviewer that it was tedious to adjust each wheel when he wanted to change the cutting height.
Fortunately the Snow Joe + Sun Joe Company backs the quality of the mower with a full two-year warranty. With a 14-inch blade this mower is meant for yards that are acre or smaller and the 16-inch deck makes it easy to get into tight spots.
