942-04053C Lawn Mower Blades Set for 50'' Deck Compatible with Cub Cadet MTD Troy-Bilt RZT50 LGT LT1050, Replaces 942-04053B 942-04056c 742-04053, High-Lift (3 Packs)

What It Is

This is a set of three high-lift lawn mower blades designed for 50-inch cutting decks, specifically compatible with Cub Cadet, MTD, and Troy-Bilt models like the RZT50, LGT, and LT1050. The high-lift design improves grass clipping discharge and bagging performance, making it ideal for thick or tall grass.

Fitment & Compatibility

Before buying, verify your deck size is exactly 50 inches (measured blade tip to tip). Check your model number against Cub Cadet, MTD, or Troy-Bilt lists—these blades replace OEM part numbers 942-04053B, 942-04056C, and 742-04053. Measure your existing blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and spindle pattern (typically 5-point star). Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket blades at a lower price than OEM; steel thickness and sharpness are adequate for residential use but may dull faster than factory blades in heavy conditions.
• Installation: Moderate difficulty—requires a socket wrench and torque wrench; tighten blade bolts to 45-55 ft-lbs. Use a blade removal tool or block the blade to prevent spinning.
• Common Gotcha: High-lift blades create more suction, which can strain the engine or cause poor mulching if your deck is designed for low-lift blades. Also, check for proper balance after installation to avoid vibration.
• Quantity: Includes three blades—enough for a 50-inch deck with three spindles. Verify your deck has three blades, not two.

Should You Buy It

Buy this set if you own a Cub Cadet, MTD, or Troy-Bilt with a 50-inch deck and need a budget-friendly replacement for standard cutting or bagging. Avoid if you require OEM-grade durability for commercial use or if your deck is designed for low-lift blades (check your manual).
