8TEN LawnRAZOR Blade for Cub Cadet MTD XT1-LT50 ZT2 50 50-Inch Deck 742P05094 742-05094 490-110-C193 Mulching 3 Pack

What It Is

The 8TEN LawnRAZOR Blade (3-pack) is a mulching blade set designed for 50-inch decks on Cub Cadet and MTD lawn tractors, specifically models like the XT1-LT50 and ZT2 50. It replaces OEM parts 742P05094, 742-05094, and 490-110-C193, and is built to cut grass into fine clippings for nutrient recycling.

Fitment & Compatibility

Before buying, verify your deck is exactly 50 inches (not 46 or 54). This blade fits Cub Cadet XT1-LT50, ZT2 50, and similar MTD-built tractors with a 50-inch stamped deck. Check your current blade’s part number—if it’s 742P05094, 742-05094, or 490-110-C193, this is a direct swap. Measure the blade length (should be ~20.5 inches), center hole diameter (typically 1 inch), and offset (usually 0.5–0.75 inch). 8TEN is an aftermarket brand, not OEM, so verify your spindle shaft and blade alignment match OEM specs. Also confirm your deck uses a 3-blade system (not 2 or 4 blades).

Key Things to Know

• Quality vs. OEM: These are heat-treated, hardened steel blades with a painted finish. They’re comparable to OEM in durability but may not last as long on rocky or sandy soil due to faster edge dulling.
• Installation: Requires a 15/16-inch or 5/8-inch socket (depending on your spindle nut). Torque to 70–90 ft-lbs. Use a blade removal tool or block the deck to prevent spinning. No special adapters needed.
• Mulching vs. Bagging: These are mulching blades with a curved, lifted design. They won’t work well for side-discharge or bagging—expect clumping if you don’t mow often. For bagging, stick with OEM high-lift blades.
• Common Gotcha: Some users report the blade tip-to-deck clearance is slightly tighter than OEM, so check for rubbing after installation. If you hear a scraping sound, re-check blade alignment or add a thin washer as a spacer.

Should You Buy It

Buy this if you want a cost-effective mulching upgrade for your Cub Cadet or MTD 50-inch deck and mow regularly (every 5–7 days) on clean, well-maintained lawns. Avoid if you need OEM-certified parts for warranty reasons, prefer bagging, or mow in rough terrain where blades take heavy abuse—OEM may last longer there.
