SUPER RECYCLE: The primary function of Toro SuperRecycler mowers is ultra-fine mulching of grass. Did you know that it is not necessary to collect your grass when you cut it? In fact, leaving grass or shredded dead leaves on your land is a natural fertilizer of much higher quality than most fertilizers on the market. Sure, almost any mower can mulch, but the patented Super Recycler Cutting System features a plated blade, cutting accelerator and deflectors that combine to provide Toro's best cutting system. So for people who don't pick up grass with a bag and want a healthy lawn, this line of mowers is for you.
