8TEN Spindle High Lift Blade Kit for MTD Cub Cadet 46 inch Cut Deck XT1-LT46 XT2-LX46 T225 T240 T2800 T3100 T8600

What It Is

The 8TEN Spindle High Lift Blade Kit is a set of three replacement blades designed for 46-inch cut decks on select MTD-built Cub Cadet lawn tractors. These high-lift blades generate increased airflow to improve grass clipping discharge and bagging performance, making them ideal for thick or damp grass.

Fitment & Compatibility

Before buying, verify your mower has a 46-inch deck (measure cutting width, not chassis). This kit fits Cub Cadet XT1-LT46, XT2-LX46, T225, T240, T2800, T3100, and T8600 models, plus other MTD brands (e.g., Troy-Bilt, Craftsman) with a 46-inch, 3-blade spindle setup. Check OEM part numbers: 742-0763, 742-0798, 742-0800 are common cross-references. Measure blade length (typically 18.5 inches), center hole diameter (1 inch), and spindle pattern (3-point star). Ensure your deck uses standard star-shaped spindles, not offset or oval holes.

Key Things to Know

• Quality & durability: Blades are heat-treated steel with a powder coating for rust resistance; most users report 2–3 seasons of life with normal use.
• Installation difficulty: Moderate—requires a socket set and torque wrench (recommended 40–50 ft-lbs). Lift deck safely, use jack stands; blades are sharp.
• Common gotchas: High-lift blades increase engine load and may cause vibration if not balanced. Always balance blades after installation. They can also throw debris farther, so avoid mowing near gravel or loose objects.
• Performance trade-off: Better bagging and discharge, but slightly reduced battery runtime on electric-start models and more noise.

Should You Buy It

This kit is right for you if you own a compatible 46-inch Cub Cadet and want improved bagging or discharge in heavy grass, and you’re comfortable with basic blade installation and balancing. Avoid if you prefer standard lift blades for a quieter, lower-drag cut on dry, short lawns.
