942-04053C Mower Blades Fit for Cub-Cad et RZT 50" Tractors, 742-04053 High Lift Blade Fit for Cub-Cad et Troy Bilt LT1050 LTX1050 50" Deck 742-04053A 742-04123, 942-04123, 3 Pack

What It Is

This is a 3-pack of 50-inch high-lift mower blades designed to replace OEM parts on Cub Cadet and Troy Bilt zero-turn and lawn tractors with a 50-inch cutting deck. The high-lift design improves grass clipping discharge and bagging performance compared to standard blades.

Fitment & Compatibility

Before buying, verify your mower deck measures exactly 50 inches (not 46 or 54). These blades fit Cub Cadet RZT 50 models and Troy Bilt LT1050/LTX1050 series with a 50-inch deck. Cross-reference with OEM part numbers 742-04053, 742-04053A, 742-04123, and 942-04123. Measure your existing blade length (should be ~20.5 inches), center hole diameter (typically 1 inch), and spindle hole pattern (usually 5-point star). These are aftermarket replacements—not OEM—so check that the blade thickness and lift angle match your original for proper cutting and deck clearance.

Key Things to Know

• High-lift trade-off: Better bagging and discharge, but more engine load and slower blade tip speed. Not ideal for thick, wet grass.
• Installation: Straightforward with a socket wrench and blade removal tool. Torque spindle bolts to 70-80 ft-lbs. Use thread locker if not specified.
• Balance: Aftermarket blades may require balancing out of the box. Check with a blade balancer to avoid vibration and spindle wear.
• Sharpness: Typically not pre-sharpened to OEM standards. Expect to sharpen before first use for best cut quality.

Should You Buy It

Buy these if you have a 50-inch Cub Cadet RZT or Troy Bilt LT1050/LTX1050 and want an affordable three-pack for regular blade changes. Skip them if you need OEM fitment, run in heavy or wet grass, or prefer blades ready to cut out of the box.
