What It Is

This is a 2-pack of 42-inch deck mower blades (models 759-3830 / 742-04101) designed for select MTD, Troy-Bilt, and Cub Cadet lawn tractors. They are a direct replacement for worn or damaged OEM blades, intended for standard residential grass cutting on mid-size garden tractors like the LT1042, LT2042, LT2180, and LT1018.

Fitment & Compatibility

Before buying, confirm:

• Deck size: These blades fit only 42-inch cutting decks. Measure your deck width or check your model’s spec sheet.
• Model numbers: Compatible with MTD, Troy-Bilt, and Cub Cadet tractors listed (e.g., LT1042, LT2042, LT2180, LT1018). Not for all LT-series; verify your exact model.
• OEM cross-references: Replaces OEM part numbers 742-3033 and 759-04081. If your current blade matches these, it’s a direct fit.
• Blade measurements: Each blade is approximately 21 inches long, with a 5-point star center hole and 0.5-inch offset. Measure your old blade’s length and hole pattern to confirm.
• Aftermarket note: This is a non-OEM (aftermarket) blade. It should mount correctly, but tolerances may vary slightly from factory parts.

Key Things to Know

• Quality vs. OEM: Aftermarket blades can be slightly thinner or less balanced than OEM. Check for straightness and balance before installation.
• Installation difficulty: Easy with basic tools—jack up the deck, remove the center bolt, swap blades, and torque to 40-50 ft-lbs. Use a blade removal tool for safety.
• Sharpness: Blades come sharp, but may need a quick edge hone for optimal cut if you’re picky.
• Common gotcha: Ensure the blade orientation (cutting edge facing the direction of rotation) matches your deck. Wrong side up can damage the blade or deck.

Should You Buy It

Buy these if you have a compatible 42-inch MTD/Troy-Bilt/Cub Cadet tractor and want a budget-friendly replacement for dull or damaged blades. They’re fine for typical residential mowing, but if you demand perfect balance or OEM durability for heavy use, consider spending more on factory originals.
