8TEN LawnRAZOR Blade for Cub Cadet ZT1 ZT2 ZTS1 XT1-LT50 Troy Bilt Super Bronco XP 50-Inch 742P05094 (Mulching) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a mulching blade set designed to replace OEM part 742P05094 on select 50-inch Cub Cadet and Troy-Bilt zero-turn and lawn tractors. It cuts grass into fine clippings for nutrient recycling, ideal for frequent mowing and clean-up.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 50 inches—this blade only fits 50-inch cutting decks. Compatible models include Cub Cadet ZT1, ZT2, ZTS1, and XT1-LT50, plus Troy-Bilt Super Bronco XP 50-inch. Check your current blade’s center hole (must be 5/8-inch round), overall length (20.5 inches), and wing thickness. This is an aftermarket replacement for OEM 742P05094; if your mower uses a different OEM number (e.g., 942-05094), cross-reference dimensions before ordering. Measure your existing blade to confirm—don’t rely solely on model name.

Key Things to Know

• Mulching vs. side-discharge: These blades are designed for mulching only. If you bag or side-discharge often, consider a standard/combination blade instead.
• Installation difficulty: Moderate—requires a socket wrench and blade removal tool. Torque to 70-80 ft-lbs. Lift the deck or remove blades safely with jack stands.
• Common gotcha: The 3-pack includes three identical blades, but some 50-inch decks use two blades (others use three). Count your deck’s spindles before buying.
• Quality: 8TEN blades are heat-treated and coated for rust resistance. They balance well but may need light re-sharpening after heavy use.

Should You Buy It

Buy this if you own a 50-inch Cub Cadet or Troy-Bilt with a three-blade deck, want a budget-friendly mulching upgrade over OEM, and mow regularly enough to benefit from fine clippings. Skip it if you side-discharge or bag, or if your deck uses only two blades.
