My yard isn't that big, so a 21" will do. I don't need self propelled, I can push with my own power, plus that's less stuff to break. So are the hondas really worth the extra money as opposed to Home Depot's 21" mower. Here are my choices thus far: Yard Machine Honda HRR216PDA Honda HRC216PDA Is the residentail Honda really worth the extra $140? We can go a step further and ask if the Commercial Honda will be worth the extra $550? It's just my yard which is about 1/3 acre.
