Agri-Fab 43055 Pin, Hair 3/32 by 10.8

What It Is

The Agri-Fab 43055 is a hairpin cotter pin, 3/32 inch thick and 10.8 inches long. It’s used to secure attachments or pivot points on lawn tractors, spreaders, and other tow-behind equipment—typically where a quick-release, non-threaded fastener is needed.

Fitment & Compatibility

Before buying, measure the hole diameter you’re inserting it into—this pin fits holes up to about 3/32 inch (2.4 mm). It’s 10.8 inches long, so check that your application has clearance for that length (e.g., through a hitch or bracket). This is a universal aftermarket part, not OEM-specific, so it will work on any brand (John Deere, Cub Cadet, Husqvarna, etc.) as long as the hole size and length match. No deck size or model number needed—just verify the pin’s diameter and length against your original. If your original pin is thicker or shorter, this won’t substitute.

Key Things to Know

• Quality concerns: The 3.4 rating and low review count suggest inconsistent fit or finish—some users report the pin bends easily under heavy load.
• Installation is trivial: Push through the hole, then spread the hairpin legs to lock. No tools required.
• Common gotcha: The 10.8-inch length is unusual—most applications use shorter pins (2–4 inches). Double-check your clearance; a pin this long can snag on debris or bend if it protrudes too far.
• Not for high-stress uses: Avoid using this on critical safety points (e.g., mower deck lift links). It’s best for light-duty attachments like spreader hitches or bagger chute pins.

Should You Buy It

This is a budget-friendly, universal pin for light-duty, non-critical applications where exact OEM parts aren’t needed. If you need a long hairpin for a spreader or tow hitch and can tolerate potential bending under heavy use, it’s fine. For critical safety parts or if you need a shorter, thicker pin, look elsewhere.
