By adding on the Recycler system, you create your own natural fertilizer. This patented system cuts grass clippings 6-8 times, turning them into a fine nutrient-rich mulch to feed your lawn all season. The secret lies in the unique ‘kickers’ and baffles that direct clippings back into the blades to be re-cut before being released into your lawn.
