50" Lawn Mower Deck Xtreme Blades Fit for Cub Cadet XT1-LT50 ZT1-50 Troy Bilt Mustang 50 Replaces OEM 742-05094-X 742P05094-X (Toothed Mulching) 3 Pack

What It Is

This is a set of three toothed mulching blades designed for 50-inch cutting decks, specifically engineered for Cub Cadet XT1-LT50 and ZT1-50, as well as Troy-Bilt Mustang 50 models. They replace OEM part numbers 742-05094-X and 742P05094-X, and are intended for users who prefer fine mulching over side discharge or bagging.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 50 inches (not 46 or 54). These blades fit Cub Cadet XT1-LT50, XT2-LX50, ZT1-50, ZT2-50, and Troy-Bilt Mustang 50 models with OEM 742-05094-X or 742P05094-X blades. They are aftermarket replacements, not genuine Cub Cadet parts. Check your current blade’s center hole size (should be 1-inch diamond) and overall length (approx. 20.5 inches). Verify the blade’s thickness matches your spindle (typically 0.25 inches). If your deck uses a different blade pattern (e.g., flat or high-lift), these mulching blades may not fit or perform as expected.

Key Things to Know

• Mulching performance: The toothed design chops clippings finer than standard blades, but requires a mulching plug/kit on your deck for best results. Without it, clippings may clump.
• Installation difficulty: Easy if you’re comfortable with a socket wrench and jack stands. Use a blade removal tool to prevent spinning. Torque bolts to 40-50 ft-lbs and recheck after 1 hour of use.
• Balance check: Aftermarket blades may need balancing before installation. Unbalanced blades cause vibration, uneven cuts, and premature spindle wear.
• Durability: Heat-treated steel holds an edge well for normal residential lawns, but hitting rocks or roots can cause bending or chipping. Not ideal for heavy commercial use.

Should You Buy It

If you own a 50-inch Cub Cadet or Troy-Bilt deck and want a fine, clean mulch without spending for OEM blades, this is a solid value at $63. It’s best for homeowners with average-sized lawns who mow regularly and don’t need heavy-duty commercial durability. Avoid if you primarily side-discharge or bag, or if your deck isn’t 50 inches exactly.
