10TopTenReview's 2015 lawnmower ratings identify the Honda HRX, Honda HRR and Toro Personal Pace as the best mulching mowers. The Honda HRX, also 10TopTen's most highly rated lawnmower overall, has a unique dual blade and a domed deck that keeps clippings suspended while they are mulched, resulting in an extremely smooth, velvet-like lawn. The Pace is noted for its propulsion and adjustment capabilities and the Toro 20332 for the ease of switching between bagging and mulching.
Other mowers making the top 10 are the Snapper, the Cub Cadet SC 500 EZ, the Husqvarna 7021R, the Craftsman 37591 and the Craftsman 37710. The Craftsman 37591, lacking some features of other top mulching mowers, is still well-regarded due to its overall design. The Craftsman 37710 is recognized for its wide cutting area, easy clean-up and folding arm for stowing. Consumer Reports' 2015 review of the best push gas mowers includes Yard Machines 11A-B96N mower as one of the best for its mulching, bagging and evenness in the discharge mode.
Curved blade surfaces and extra cutting surfaces along the edges of the blade distinguish mulching blades from standard mowing blades. Mulching blades are sometimes referred to as "three-in-one blades," as they work for mulching, discharging and bagging. Attempting to mulch wet grass can lead to clumping and a blocked blade. The best mowers make it easy for operators to switch between the three modes.
