CUB CADET 942-04053-X Xtreme 50" Deck Blade 3-Pack RZT50 i1050 LTX1050 Lawn Tractors

What It Is

This is an OEM Cub Cadet 3-pack of 50-inch deck blades (part 942-04053-X) designed for Xtreme series mowers and select RZT, i1050, and LTX1050 lawn tractors. These blades are for heavy-duty cutting—thick grass, large lawns, or commercial-style residential use.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 50-inch cutting decks. Measure your deck width to confirm.
• Model series: Compatible with Cub Cadet RZT50, i1050, LTX1050, and Xtreme series mowers. Verify your exact model number (e.g., RZT50, LTX1050) on the machine’s ID tag.
• OEM vs aftermarket: These are genuine Cub Cadet parts, not aftermarket. They match original factory specs for fit and balance.
• Blade measurements: Each blade is roughly 16.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and two 1/4-inch offset holes. Measure your old blade length and hole pattern to confirm.
• Deck type: Not for 42-inch, 46-inch, or 54-inch decks. Only 50-inch Xtreme or compatible RZT/i1050/LTX1050 decks.

Key Things to Know

• Quality: OEM blades are thicker and harder than many aftermarket options, lasting longer in tough conditions. They also cut cleaner with less vibration.
• Installation difficulty: Easy—about 15 minutes per blade with basic tools (socket wrench, jack or lift). Use a block of wood to prevent blade spin when loosening/tightening the bolt. Torque to 70-90 ft-lbs.
• Common gotchas: Don’t mix old and new blades—replace all three at once for balanced cutting. The blade bolt is reverse-threaded on some models (lefty-tighty, righty-loosey). Check your manual or look at the bolt head for an “L” or “R” marking.
• Sharpening: You can sharpen these once or twice, but the hardened steel makes it harder than cheap blades. After that, replace them.

Should You Buy It

If you have a Cub Cadet with a 50-inch Xtreme, RZT50, i1050, or LTX1050 deck and want durable, factory-fit blades that cut cleanly and last through thick grass or tough conditions, this 3-pack is a solid buy. It’s not for budget shoppers who only mow a small, easy lawn—but for heavy use, it’s worth the price.
