What It Is

This is a direct replacement gas cap for select John Deere lawn tractors and zero-turn mowers, designed to seal the fuel tank and prevent leaks or debris ingress. It fits models like the X300 series, 300 series, and Z200/Z400 zero-turns.

Fitment & Compatibility

Before buying, verify your mower model matches the list (e.g., 325, 335, 345, LT150, LT160, X300-X729, Z225-Z465). This cap is an aftermarket part, not OEM John Deere, but it’s designed to match the original fit. Check the cap’s outer diameter (approx. 2.5 inches) and thread pattern—most John Deere caps use a standard 2-inch threaded neck. If your tank has a vented or non-vented requirement, note this cap is typically non-vented (check product details for confirmation). Deck size is irrelevant; only the fuel tank opening matters.

Key Things to Know

• Quality: Rated 4.6/5 stars from 60 reviews; users report solid seal and durable plastic construction, though some note the tether strap is shorter than OEM.
• Installation: Simple twist-on replacement—no tools needed. Takes 30 seconds.
• Gotchas: If your original cap was vented, this non-vented cap may cause pressure buildup or fuel starvation on older models with vented tanks. Confirm your John Deere’s tank type. Also, the cap may not fit tanks with a locking mechanism.
• Price: At $9.95, it’s a budget-friendly alternative to OEM caps ($15–$25), but check if the tether attachment point matches your tank’s design.

Should You Buy It

Buy this cap if you need a quick, inexpensive fix for a lost or broken gas cap on a compatible John Deere model and your tank is non-vented. It’s a solid value for the price, but skip it if you require a vented cap or an exact OEM tether length—go with an OEM part instead.
