CUB CADET 490-110-F192 High Lift Blade Set S-Shape Center Fab ZTS1 ZT1 XT2 XT1 LX46 LT46 46 CMXGZAM110192 742P05648

What It Is

This is a set of three high-lift blades from Cub Cadet, designed for 46-inch fabricated (fab) decks on zero-turn and lawn tractors. The S-shape center and high-lift profile create stronger vacuum for superior bagging and side-discharge performance compared to standard blades.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size – This set fits only 46-inch fabricated steel decks (not stamped decks). Common on Cub Cadet ZTS1, ZT1, XT2, XT1, LX46, and LT46 models.
• OEM part cross-reference – Replaces Cub Cadet OEM 490-110-F192, 742P05648, and MTD/CCA 490-110-F192. Also compatible with aftermarket part 46 CMXGZAM110192.
• Center hole & blade length – Each blade measures approximately 15.5 inches long with a center hole diameter of 5/8 inch. Confirm your spindle pattern matches (three-hole, 5/8-inch center).
• Not for stamped decks – Do not use on 46-inch stamped decks (common on older LT/LX series). Check your deck’s underside for “FAB” or “FABRICATED” marking.

Key Things to Know

• Installation difficulty – Easy to moderate. Requires a socket wrench, torque wrench (recommended 70–90 ft-lbs), and possibly a blade removal tool. Always lift or block the deck safely.
• High lift = more power draw – These blades create more drag, so you may notice slightly higher engine load or reduced runtime on battery zero-turns. Not ideal for underpowered mowers.
• Bagging performance – Excellent for leaf mulching and heavy grass bagging. The S-shape center reduces clumping and improves discharge flow.
• Balance check – Out of the box, these blades are balanced, but always check with a blade balancer before installing. Unbalanced blades cause vibration and spindle wear.

Should You Buy It

Buy this set if you have a Cub Cadet with a 46-inch fabricated deck and need maximum lift for bagging or side-discharge work, especially in heavy grass or leaf conditions. Skip it if you primarily mulch (high-lift blades throw clippings up, not down) or if your deck is a stamped 46-inch model—they won’t fit.
