Stens offers best-of-class mulching blades for maintaining perfect lawns. The profile of the blade features an expanded cutting edge and a curved contour that multitasks in three ways. As the blade swirls, the grass blades are pulled upwards, which allows for a clean and uniform cut across the lawn. Next, the clippings circulate inside the deck, giving the blade time to chop them into smaller pieces. The small pieces of grass clipping are then discharged evenly over the lawn. The clippings are spread uniformly to avoid clumps and piles left behind in the lawn.
