What It Is

This is a set of three 44-inch mower blades designed for select Cub Cadet, MTD, and Troy-Bilt lawn tractors. They are a direct replacement for OEM part numbers 742-3036, 759-3929, and 759-3939, and are intended for medium-to-large residential properties with decks requiring a 44-inch cutting path.

Fitment & Compatibility

Before buying, confirm your deck is a 44-inch deck—measure the cutting width if unsure. These blades replace OEM numbers 742-3036, 759-3929, and 759-3939. They fit popular Cub Cadet models like the GT2186, GT2544, 208, 209, and 2518, as well as many MTD and Troy-Bilt tractors with the same deck size and spindle pattern. Check that your deck uses a three-blade configuration (not two or four). Measure the center hole diameter (typically 1-inch) and the overall blade length (should be roughly 15-16 inches per blade). These are aftermarket blades, not OEM, but match OEM specs for fit and function.

Key Things to Know

• Quality: Made from heat-treated steel for durability. Sharp out of the box but will need sharpening after 10-15 hours of use on thick grass.
• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or a block of wood to hold the blade). Always disconnect the spark plug and wear gloves.
• Common gotchas: These blades are not universal—they will not fit 42-inch or 46-inch decks. Also, ensure your spindle bolts are not seized; apply penetrating oil beforehand. The blades are sold as a set of three, so you’ll replace all at once for balanced cutting.
• Weight: Heavier than some OEM blades, which can help with mulching but may increase engine load slightly.

Should You Buy It

If you own a compatible 44-inch Cub Cadet, MTD, or Troy-Bilt tractor and want a budget-friendly, high-rated aftermarket set that matches OEM performance, this is a solid buy. It’s best for homeowners who mow weekly and want sharp, balanced blades without paying OEM prices. Not ideal for commercial use or if you need exact OEM branding.
