120-6241 Trailing Shield Flap Compatible with Toro 30 Timemaster Lawn Mower 20200, 20975, 20977, 23511, 23513, 33511, 33513 for Lawn Mower Replacement Parts Flap/Mower Guard.

What It Is

The 120-6241 trailing shield flap is a replacement rubber flap for the rear discharge opening of Toro 30-inch TimeMaster mowers (models 20200, 20975, 20977, 23511, 23513, 33511, 33513). It redirects clippings downward and helps prevent debris from kicking back at the operator.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 30 inches and your model number matches one of those seven listed (check the plate under the seat or near the engine). This is an aftermarket part, not OEM Toro; the OEM equivalent is Toro 120-6241. Measure the old flap: it should be roughly 30 inches wide and about 6–7 inches tall. If your deck has a different width or mounting hole pattern, it won’t fit. Also verify you have the two metal pins or bolts that secure the flap—this part includes only the rubber flap, not hardware.

Key Things to Know

• Quality varies: Some users report the aftermarket rubber is thinner and less flexible than OEM, which can cause it to tear faster or not seal as tightly.
• Installation is quick: Takes about 5 minutes with a wrench—remove two bolts, swap flaps, and reinstall. No special tools needed.
• Watch the hole alignment: The pre-punched holes may not line up perfectly with your deck’s mounting pins; you may need to drill new holes or ream existing ones slightly.
• Low rating (3.0/5): The six reviews suggest mixed satisfaction—most complaints are about fitment issues or premature wear, not function.

Should You Buy It

If your original Toro flap is cracked or missing and you need a cheap, functional replacement for a 30-inch TimeMaster, this aftermarket option works—but expect to tweak the fit and accept shorter lifespan. For a guaranteed fit and longer durability, spend more on the genuine Toro 120-6241.
