CUB CADET 942-05052-X 50" 6 Pt Star Xtreme Mulch Blade RZT GT LX SX XT1 XT2 ZT1 3 Pack

What It Is

The CUB CADET 942-05052-X is a set of three 50-inch Xtreme Mulch Blades designed for Cub Cadet RZT, GT, LX, SX, XT1, XT2, and ZT1 zero-turn and lawn tractors. These 6-point star blades are engineered for fine mulching and leaf shredding, reducing clippings into smaller particles for better lawn nutrition.

Fitment & Compatibility

• Deck size: Fits only 50-inch cutting decks. Measure your deck width before ordering.
• Model check: Compatible with RZT, GT, LX, SX, XT1, XT2, and ZT1 series. Verify your specific model number on the deck or in the manual.
• OEM vs aftermarket: This is an OEM Cub Cadet part (replaces 942-05052, 942-05052A, 942-05052B). Direct bolt-on for original equipment; may require minor modifications for aftermarket spindles.
• Measurements: Blade length is 16.5 inches, center hole 5/8-inch diameter, 1-inch star center. Confirm your spindle’s center hole shape and size—some older decks use a round hole.

Key Things to Know

• Mulching performance: The 6-point star design creates more cutting edges than standard 2-point blades, producing finer clippings and reducing bagging frequency.
• Installation difficulty: Easy to swap with basic tools—just a socket wrench and torque wrench. Use thread locker on spindle bolts to prevent loosening.
• Wear life: Expect 25-50 hours of use depending on debris and terrain. Sharpen or replace when edges round or chips appear.
• Common gotcha: These are not for bagging or side-discharge. Using them with a bagger can clog the chute. They work best with a mulch kit installed.

Should You Buy It

If you own a 50-inch Cub Cadet RZT/GT/XT/ZT series and prioritize fine mulching over bagging or side-discharge, this OEM three-pack is a solid investment. It’s a direct fit, built to last, and priced competitively for genuine Cub Cadet quality. Skip it if you need standard lift blades for bagging or have a non-compatible deck size.
