In its biggest lawn mower tests ever, Consumer Reports rates more than 70 mowers. Key is how evenly they cut and mulch … how much their bags can hold … and how well they discharge clippings.  (NATSOT: Discharging)  Several of the mowers tested are electric, including some that are cordless. Electrics are better for the environment, and they're quieter.   But Consumer Reports finds  self-propelled gas mowers are generally much better at cutting grass.    "You'll pay more for a self-propelled mower, but if you've got a larger lawn, or if you just want an easier time mowing your lawn, then this is a feature that you should consider."  But don't pay extra for large rear wheels. They're not worth it.   Peter Sawchuk, "We found in our testing that because these wheels are located father back, it takes more force to push down and turn the mower, compared to a conventional mower."     Among self-propelled mowers, Consumer Reports named this  Toro Recycler a Best Buy for 350 dollars. It has rear-wheel drive and performs almost as well as mowers that cost twice as much.
