120-7011 Trailing Shield Flap Replacement 107-7496, 114-1586 for Toro 21" Walk Lawn Mower and Recycler Lawn Mower Models 20381 20382 20383 20384 20792 20797

What It Is

This is a replacement trailing shield (mulch flap) for Toro 21-inch walk-behind and Recycler mowers. It sits at the rear of the deck to block debris from kicking back toward the operator and helps contain clippings for better mulching.

Fitment & Compatibility

Check your model number – fits Toro models 20381, 20382, 20383, 20384, 20792, and 20797. Also replaces OEM part numbers 120-7011, 107-7496, and 114-1586. Measure your existing flap – this one is approximately 21 inches wide and 3 inches tall. It’s a direct OEM-style replacement, not an aftermarket universal flap, so no cutting or drilling needed for listed models. Verify deck style – only fits 21-inch steel decks with the factory mounting slot pattern; does not fit older aluminum decks or 22-inch models.

Key Things to Know

• Installation is simple – remove the old flap by pulling out the two retaining pins (or bolts), slide the new one into the slots, and reinstall the pins. No tools required on most models.
• Quality is OEM-equivalent – made from durable rubber/plastic composite that resists cracking and UV damage. Holds shape better than some aftermarket flaps that go floppy after a season.
• Common gotcha – if your mower has a bagger kit, the trailing shield may need to be removed or swapped for a bagger-specific chute. This flap is for mulching/side-discharge only.
• Check for pin wear – the retaining pins or hardware can rust or bend; order new pins separately if yours are corroded.

Should You Buy It

If you own a compatible Toro 21-inch Recycler and your current flap is cracked, torn, or missing, this is a direct, affordable fix that restores safety and mowing performance. It’s a no-brainer for DIY owners who want to avoid a trip to the dealer.
