This genuine Toro OEM turbo baffle kit is designed for Toro GrandStand stand-on mowers and modifies the airflow under the cutting deck to improve clipping discharge performance in heavy, dense, or wet grass conditions. The turbo baffle redirects air movement beneath the deck to increase the velocity at which clippings are expelled through the discharge chute, reducing the tendency for clippings to clump or block in challenging mowing conditions. Verify your model and serial number before ordering.
