490-110-C203 Mulching Blade Compatible with Cub Ca det 46'' Deck Enduro XT1-LT46 XT2-LX46 Ultima ZT1-46 ZTS1-46, 742P05510-X Lawn Mower Toothed Blade fits for Troy-Bilt Super Bronco Mustang, 2 Pack

What It Is

This is a 2-pack of mulching blades designed for 46-inch cutting decks on Cub Cadet Enduro Series tractors (XT1, XT2) and Ultima ZT1/ZTS1 zero-turns, plus Troy-Bilt Super Bronco and Mustang models. The toothed edge chops grass finer for nutrient recycling, ideal for frequent mowing without bagging.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 46 inches. Measure your deck’s cutting swath, not the mower model alone.
• Model match: Verified for Cub Cadet XT1-LT46, XT2-LX46, Ultima ZT1-46, ZTS1-46; also fits Troy-Bilt Super Bronco 46 and Mustang 46. Cross-reference your OEM part number (e.g., 742P05510-X) with your owner’s manual.
• Physical specs: Each blade is ~20.5 inches long with a 1-inch center hole and 5-point star drive. Measure your old blade’s length and center hole shape. This is an aftermarket replacement, not OEM Cub Cadet/Troy-Bilt, so verify that the star pattern matches your spindle.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool (or a block of wood to lock the blade). Torque to 70–90 ft-lbs. Always disconnect the spark plug and battery first.
• Mulching vs. side-discharge: These blades work best with a mulching plug installed. If you side-discharge, you’ll get clumping in tall or wet grass. For bagging, use standard high-lift blades instead.
• Durability: Heat-treated steel with a painted finish—good for residential use. Expect 25–50 hours before dulling, depending on debris. Sharpen or replace sooner if you hit rocks or roots.
• Common gotcha: The star drive pattern can be slightly tight on some spindles. If it doesn’t seat fully, check for burrs on your spindle or blade adapter. Do not force it.

Should You Buy It

Buy this if you have a compatible 46-inch Cub Cadet or Troy-Bilt mower and want a budget-friendly mulching upgrade. It’s a solid value for homeowners who mow weekly and want finer clippings without bagging. Skip it if you need OEM exactness or have a different deck size.
