Country Clipper D-3904

What It Is

The Country Clipper D-3904 is a replacement blade for zero-turn mowers, designed specifically for Country Clipper models. It handles cutting grass on residential or commercial properties, intended as a direct swap for worn or damaged factory blades.

Fitment & Compatibility

• Deck size: Fits 42-inch, 48-inch, and 54-inch Country Clipper decks. Measure your blade length (typically 18.5 inches) and center hole diameter (usually 5/8 inch) against the D-3904 specs to confirm.
• Model/brand fit: OEM replacement for Country Clipper zero-turn mowers. Not compatible with other brands without verifying spindle and blade pattern.
• OEM vs aftermarket: This is an OEM part, so it matches original blade thickness, heat treatment, and hole alignment—no aftermarket fitment guesswork.
• What to check: Verify your existing blade part number (often stamped on the blade) matches D-3904. Also check deck spindle bolt size (usually 5/8-inch) to ensure your tools fit.

Key Things to Know

• Quality: OEM-grade steel with a hardened edge for longer life than many generic blades. Expect 25–50 hours of cutting before dulling.
• Installation difficulty: Easy—requires a socket wrench and a blade removal tool or block of wood to prevent spin. Torque bolt to 70–90 ft-lbs.
• Common gotcha: Don’t mix left and right blades if your deck uses a staggered pattern. The D-3904 is a universal blade, but confirm your deck uses identical blades on all spindles.
• Sharpening: Can be sharpened 2–3 times before replacement, but avoid over-sharpening as it reduces blade balance.

Should You Buy It

Yes, if you own a Country Clipper zero-turn with a compatible deck and want a reliable, no-surprise OEM blade. It’s a safe choice for DIY replacement, especially if you prefer factory specs over aftermarket options. Skip it if you have a different brand deck or need a mulching/ high-lift blade—this is a standard lift blade for side-discharge use.
