8TEN LawnRAZOR Blade for Cub Cadet MTD Troy Bilt XT1-LT50 ZT1-50 50-Inch Deck 742P05094-X 742-05094-X Toothed 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a toothed, aftermarket replacement blade set (3-pack) designed for 50-inch cutting decks on select Cub Cadet, MTD, and Troy-Bilt lawn tractors and zero-turn mowers. It’s built for mulching and bagging—the serrated edge helps shred grass clippings finer for better nutrient recycling.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Must be exactly 50 inches. Measure your deck’s cutting swath (blade tip to blade tip). This set won’t fit 46-inch or 54-inch decks.
• OEM part numbers: Cross-reference your current blade’s part number with OEM numbers 742P05094-X and 742-05094-X (used on Cub Cadet XT1-LT50, ZT1-50, and many Troy-Bilt/Toro 50-inch decks). If your blade has a different number, measure length and hole pattern.
• Physical dimensions: Each blade is ~16.5 inches long, with a 1-inch center hole and two 1/4-inch offset mounting holes. Measure your old blade’s length, hole diameter, and center-to-center spacing. If yours is 16.5” with a 5-point star or oval hole, this won’t fit.

Key Things to Know

• Quality vs OEM: These are stamped steel, not forged. They’ll dull faster than factory Cub Cadet blades (especially in sandy or rocky soil) but are fine for typical residential lawns.
• Installation: Standard 5/8-inch socket and torque wrench. Tighten to 50-60 ft-lbs. Use a blade-stopping tool or block of wood to prevent rotation. Always replace all three blades at once for balanced cutting.
• Mulching performance: The toothed edge works well for mulching leaves and normal grass, but can leave uncut strips if the deck isn’t level. Check blade alignment after installation.
• Common gotcha: Some users report the blades are slightly thinner than OEM, which can cause vibration if not perfectly balanced. Consider having them balanced before install.

Should You Buy It

Buy this if you have a 50-inch Cub Cadet, MTD, or Troy-Bilt with the specified OEM part numbers and want an affordable mulching/bagging blade set for regular residential use. Skip it if you need heavy-duty commercial blades, run in extremely abrasive conditions, or prefer the exact OEM fit and durability—stick with genuine Cub Cadet or Oregon blades for longer life and guaranteed balance.
