When I bought my house last spring, I went for an electric mower. Unfortunately, my spouse's budget for yard tools made me not go for the best, and I got one that doesn't cut evenly(twin blades is a terrible design), and the batteries die too quickly for my 1/3 acre lot. I should have gone with a corded one. Since my neighbors were getting annoyed with how much I neglected my lawn, I bought a used gas mower. I look forward to when I can afford a robotic mower to deal with it, but in the meantime I'm going to turn a large portion of my lawn into garden, and build a fence so my neighbors aren't such busybodies about how long it is getting.
