I really need something quicker than my current setup for gated backyards. I use a Honda 21". I looked online at the Better mowers and they look good and seem reasonable. What do you think about hydro walkbehinds? What fits through standard wooden privacy fences and chain link fences? I sure don't want to buy one online and find out that it won't fit. I don't use a walk mower but around 2 hours per week, but the speed is killing my productivity. Any suggestions would be appreciated. Thanks.
