Toro OEM rear discharge kit. The discharge chute removes long, thick and moist grass from the underside of the mowing deck as quickly as possible. It also helps your mower power through the long, wet grass. This eliminates the grass clippings from building up and getting trapped in the cutting area. When it comes to reliability, Toro delivers replacement parts designed to the exact engineering specifications of our equipment. For peace of mind, insist on Toro genuine parts.
