What It Is

This is a replacement air filter for Briggs & Stratton engines used in lawn tractors and zero-turn mowers, sized for 17.5hp to 21hp single-cylinder and V-twin engines. It’s compatible with Craftsman YT3000, LT2000, Husqvarna, John Deere E110/LA125, and other models using the 793569 or 793685 filter.

Fitment & Compatibility

• Cross-reference numbers: 793569, 793685, 4241, 5415, GY21055, MIU11511, 12673. Verify your engine’s filter number matches one of these.
• Engine types: Fits B&S Intek, Endurance, and most 17.5–21hp single-cylinder or V-twin engines with a rectangular foam-plus-paper filter housing.
• Physical dimensions: Approximately 6.5” x 4.5” x 1.5”. Measure your old filter’s length, width, and thickness to confirm.
• Brand fit: Works on Craftsman, Husqvarna, John Deere, and other tractors with the compatible B&S engine. Check your model’s parts list—don’t rely on brand alone.
• OEM vs aftermarket: This is an aftermarket replacement. It matches OEM specs but may have slightly different foam density or paper pleat count. Fine for routine use.

Key Things to Know

• Quality: Durable enough for seasonal mowing; foam pre-filter traps larger debris, paper element catches fine dust. Not heavy-duty for extreme dust conditions.
• Installation: Simple—remove old filter, clean housing, drop in new one. No tools needed. Ensure the foam side faces outward (toward the air intake).
• Common gotcha: Some users report a slightly looser fit in older housings. If the filter rattles, add a thin foam strip around the edge to seal it.
• Maintenance: Replace every 100 hours or annually. In dusty conditions, clean the foam pre-filter with soapy water between changes.

Should You Buy It

If you own a lawn tractor with a 17.5–21hp B&S engine and need an affordable, reliable air filter for standard mowing, this is a solid choice. It won’t outperform OEM in extreme dust, but for most homeowners, it’s a budget-friendly, easy swap that gets the job done.
