I have been looking at switching to an electric push mower fora 1/4 acre lot. I was looking hard at Milwaukee. I wanted to keep all the batteries the same for all my power tools. After seeing more than a few reviews, I am going to let Milwaukee work the bugs out of their mower. They have been having issues with QC. Wheel bearings over pressed, mower is cutting in and out (sounds like a switch issue), uneven cuts, bags coming apart at seams, etc. Not trying to bash them, I like all the other stuff I have from them.
I am looking and going with EGO, just for lawn care and snow. If they are working well on a commercial level, one of the first post, then my place will be no big deal.
