UDC Parts 742-05094 S-Shape Mower Blades Replacement for Cub Cadet 50 Inch ZTS1 ZTS2 742P05094 Craftsman CMXGZAM110193 Z5600 Z5650 Troy Bilt 742P05512 490-110-Y193 ZT1-50/3 Pack High Lift

What It Is

This is a 3-pack of high-lift S-shape mower blades (UDC 742-05094) designed for 50-inch cutting decks on Cub Cadet ZTS1, ZTS2, Z5600, Z5650, Craftsman ZT1-50, and Troy-Bilt ZT1-50 zero-turn mowers. The high-lift design creates stronger airflow for superior grass clipping discharge and bagging performance.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 50-inch decks (not 46" or 54").
• Blade measurements: Each blade is 17.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and 0.203-inch thickness. Measure your current blades to confirm.
• OEM cross-reference: Replaces Cub Cadet 742P05094 and 742-05094, Craftsman CMXGZAM110193, and Troy-Bilt 742P05512 and 490-110-Y193. If your mower uses a different OEM number, these likely won’t fit.

Pro tip: Check your mower’s model number (not just brand) against the compatibility list. These blades do NOT fit older 50" decks with different spindle patterns.

Key Things to Know

• High-lift vs standard: High-lift blades improve bagging and discharge but create more drag, which may slightly reduce engine RPM and fuel efficiency. Not ideal for mulching.
• Installation difficulty: Easy swap—use a socket wrench and blade removal tool. Torque to 70–90 ft-lbs. Always sharpen new blades before first use (factory edges are dull).
• Common gotchas: The S-shape can bend under heavy debris (rocks, roots). Inspect after each mow. Also, these blades are thicker than OEM (0.203" vs 0.190"), so check blade clearance under the deck before installing.
• Quality: UDC is a reputable aftermarket brand. 4.6 stars from 4,300+ reviews indicates consistent sharpness and durability for residential use.

Should You Buy It

If you own a compatible 50-inch Cub Cadet, Craftsman, or Troy-Bilt zero-turn and prioritize bagging or side-discharge performance over mulching, this 3-pack offers solid value at $42.59. For heavy-duty commercial use or rocky terrain, consider a thicker, heat-treated blade instead.
