942-04053C Mower Blades for Cub Cadet 50'' Deck RZT-50 LTX1050 LT1050 50 Inch Zero Turn Riding Mower Lawn Tractor Replace 742-04056 942-04056 High Lift 6 Point Star Blades 3 Pack

What It Is

This is a 3-pack of high-lift star blades for 50-inch cutting decks on Cub Cadet zero-turn mowers and lawn tractors. Designed for mulching and bagging, the aggressive lift pattern improves clipping discharge and grass circulation in heavy-duty residential use.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be exactly 50 inches. This blade set will not fit 42-inch, 46-inch, or 54-inch decks.
• Model compatibility: Fits Cub Cadet RZT-50, LTX1050, and LT1050. Also fits select models using 50-inch fabricated or stamped decks with a 6-point star center hole and 1-inch diameter arbor.
• OEM cross-reference: Replaces OEM part numbers 942-04056, 742-04056, and 742-04053C. If your mower uses a different blade pattern (e.g., oval hole or 5-point star), these will not mount.
• Measurements: Blade length is 16.5 inches, width 2.5 inches, thickness 0.1875 inches. Check your current blade against these dimensions—especially the center hole shape and arbor size.

Key Things to Know

• Quality: Aftermarket blades at a lower price than OEM Cub Cadet. Some users report slightly thinner steel than original, but adequate for residential mowing. Not recommended for commercial use.
• Installation difficulty: Easy to moderate. Requires a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Use anti-seize on arbor bolts to prevent seizing.
• Common gotchas: The high-lift design creates more vibration if blades are not balanced. Always balance new blades before installing. Also, these blades may not fit decks with spindle guards that have limited clearance for the raised wing tips.
• Pack contents: Three blades, no hardware. You will need to reuse your existing bolts and washers.

Should You Buy It

Buy this set if you have a 50-inch Cub Cadet zero-turn or lawn tractor and need an affordable replacement for mulching or bagging. It’s a solid value for residential use, but skip it if you need OEM-grade durability for frequent commercial mowing or if your deck requires a different center hole pattern.
