16" Lawn Mower Mulching Blade is rated 3.5 out of 5 by 11.
Rated 5 out of 5 by from A must-have as a backup My WORX mower would get the best and highest rating from me. It’s a pure plus. Excellent battery power for doing my little forest on my 20 x 30-foot backyard. The technology that went into the electrical system if aväntˈɡärd. The mower instantly stopped when a thick branch get stuck in the blade. The machine sensed the overload and took over. Like automatic braking. I redid my backyard design and got rid of the rock boarders. I ordered a replacement blade just in case I run into hidden rocks. It gives me peace of mind, though I probably will never need it. The batteries hold a charge in storage and the higher 40-volt battery system let the engineers use lower current wiring and components (power = volts X amps). The grass catching bag is easy to empty, and change-over between mulching and collecting is easy and fast. Love that all four wheels raise and lower with simply one easy-to-use lever. Gasoline engines have their niche, but batteries are easily recharged, and gas, oil, spark plugs, pull chains, etc., are history for me.
