The Toro 120-7048 Lawn Mower Rear Deflector Assembly is a safety component designed to cover the rear discharge area on compatible mower decks. It works by directing grass clippings and small debris downward as the blade spins, helping prevent material from being thrown toward the operator. Its flexible construction allows it to move with the ground while maintaining protective coverage. The assembly matches the deck’s mounting points and installs easily during maintenance or replacement.
