Grasshopper Mower Air Dam Kit for Model 9552/9652 FrontMount Decks, Installs on Front, Underside of Model 9552/9652 Decks to Control Dust and Clippings, OEM 503021

What It Is

This is an OEM Grasshopper air dam kit (part #503021) that mounts to the front underside of 9552 and 9652 FrontMount mower decks. It’s designed to reduce dust and clippings blowing out the front of the deck, keeping the operator and surrounding area cleaner during mowing.

Fitment & Compatibility

• Exact models: Grasshopper FrontMount 9552 and 9652 decks only. Not compatible with other deck sizes or model numbers.
• OEM vs aftermarket: This is a genuine Grasshopper part (OEM). Aftermarket equivalents exist but may not match mounting holes or material thickness.
• Check before buying: Verify your deck model number (stamped on the deck housing). Measure the front lip width—the kit is sized for 52-inch and 62-inch decks respectively. Also confirm your deck has the factory mounting slots or holes; older decks may require drilling.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck or raising it high for access. You’ll need basic hand tools (socket set, drill if retrofitting).
• Material quality: The kit uses a flexible rubber or composite material. Some users report it can crack or warp in extreme heat or after repeated contact with obstacles.
• Dust control: Effective at reducing fine dust in dry conditions, but less effective in wet grass or heavy clippings. Does not eliminate all debris.
• Reviews: Only 2 reviews with a 2.4/5 rating—poor sample size, but suggests inconsistent fit or durability complaints.

Should You Buy It

Buy it if you operate a Grasshopper 9552 or 9652 in dusty, dry conditions and want to reduce operator exposure—and you’re okay with OEM pricing and moderate installation work. Skip it if you mow mostly wet grass, have a different deck model, or prefer a cheaper aftermarket alternative with similar results.
