What It Is

This is a 3-pack of high-lift notched mower blades designed for 50-inch cutting decks used on select Cub Cadet, Troy-Bilt, and MTD lawn tractors. The high-lift design improves grass clipping discharge and bagging performance, making them ideal for mulching or side-discharge setups.

Fitment & Compatibility

Before buying, confirm your deck deck measures exactly 50 inches from blade tip to blade tip. These blades replace OEM numbers 942-04068 and 759-4047 and fit models like Cub Cadet LT1050, GT2050, GT2550, LT1024, and compatible Troy-Bilt and MTD 50-inch deck tractors. Measure blade length (should be ~20.5 inches), center hole diameter (typically 7/16-inch or 5/8-inch), and notch pattern. Check your spindle orientation—these are notched and require the correct alignment to avoid vibration. If your deck uses a different spindle or blade offset, these won’t fit.

Key Things to Know

• Quality vs OEM: Aftermarket blades may be slightly thinner or less balanced than OEM. Inspect for burrs or uneven edges before installation.
• Installation: Straightforward—use a socket wrench, block the blade to prevent spinning, and torque to 70-90 ft-lbs. Note: these are high-lift, so they create more upward airflow; not ideal for dry, sandy soil (can kick up debris).
• Common gotcha: The notched design is specific to certain spindles. If your deck uses a smooth center hole, these won’t seat properly. Check your old blade’s notch pattern.
• Pack size: 3-pack is economical but only useful if you need three identical blades (most 50-inch decks use two blades, but some use three—verify your deck’s blade count).

Should You Buy It

If you own a 50-inch Cub Cadet, Troy-Bilt, or MTD tractor with a compatible notched spindle and want a budget-friendly alternative to OEM blades for better bagging or discharge, this 3-pack is a solid value. It’s less suitable for precision mulching or heavy-duty commercial use—stick with OEM for durability if you mow frequently over rough terrain.
