120-5218 Rear Baffle & 115-8420 Trailing Shield Flap for Toro 22in

Our review of the 120-5218 rear baffle and 115-8420 trailing shield flap finds this pair best suited for owners of Toro 22in walk-behind and Recycler lawn mowers who need a cost-effective factory-fit replacement. The bottom line: these parts restore debris control and user protection on compatible 22in decks and cover a wide range of model and serial ranges, making them a practical choice when the original baffle or flap is damaged. Installation can be fiddly for some, but once fitted the parts perform their primary function of limiting debris ejection reliably.

Key Features

• Direct replacement compatibility: Fits many Toro 22in mower models including 20330, 20331, 20370 and their C variants, so buyers can expect a match for the listed serial ranges.
• Rear baffle design: The rear baffle attaches to the back of the deck to limit the flow of grass clippings and debris, helping keep the lawn tidy during use.
• Trailing shield function: The trailing shield flap prevents debris from flying out of the mower deck and protects the user from potential injury.
• Multiple part numbers covered: Includes rear baffle part references 120-5218 and 115-1307 and flap references 105-1843, 115-8420 and 144-6431, easing identification when matching to older equipment.
• Coverage by serial ranges: Listed compatibility with specific serial ranges for many models gives extra confidence when verifying fit for 2009 and 2010 model years and later 20370/20371/20377 ranges.

Who It's For

This replacement kit is for homeowners and maintenance personnel who own a Toro 22in walk-behind or Recycler mower within the listed model numbers and serial ranges and who need to restore deck safety and debris control without buying a full new deck. It is especially useful when the original rear baffle or flap is cracked, torn or missing.

Those who prefer an easier installation experience or who require premium-feeling materials may want to plan time for careful fitting or consult a local service shop, since some users report mixed ease-of-installation and that the plastic feels lighter than OEM to certain customers.
