The Toro 121-0739 Lawn Mower Discharge Deflector directs grass clippings safely away from the mower deck during operation. Designed as a replacement discharge deflector, it fits compatible Toro lawn mowers to control the flow of discharged grass and debris from the side opening. It works by guiding clippings downward while the mower blades rotate during cutting. This supports safer mowing performance, cleaner grass distribution, improved debris control, and dependable lawn maintenance operation.
