Grasscool ZT1 50 Blades for Cub Cadet 50 inch Mower Replace 942-05052A with 6 Star Shaped Hole Ultima ZT2 Zero Turn Enduro XT1 XT2 LT50 50'' Deck Lawn Tractor Riding Replace 742-05052A (High-Lift)

What It Is

This is a set of three high-lift replacement blades designed for 50-inch Cub Cadet zero-turn mowers. High-lift blades create stronger airflow to improve grass clipping discharge and bagging performance, making them ideal for tall or thick grass conditions.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck and uses blades with a 6-star shaped center hole (not round or oval). These replace OEM part numbers 942-05052A and 742-05052A. Compatible models include Cub Cadet ZT1 50, ZT2, Ultima, Enduro XT1/XT2, and LT50 series. Measure your existing blade length (should be ~20.5 inches) and verify the blade thickness matches (typically 0.25 inches). This is an aftermarket replacement, not genuine Cub Cadet, so check that the star pattern aligns with your spindle—some aftermarket blades may have slightly looser fit.

Key Things to Know

• High-lift design increases grass lift but also creates more vibration if blades are unbalanced; always balance before installation.
• Installation requires a socket wrench and torque to 40-50 ft-lbs; use thread locker to prevent loosening.
• Common gotcha: the 6-star hole can be tight on some spindles; lightly file the hole if needed, but never force it.
• Durability is good for residential use, but these blades dull faster in sandy or rocky soil compared to OEM or hardened steel options.

Should You Buy It

Buy these if you own a 50-inch Cub Cadet zero-turn and need affordable high-lift blades for bagging or heavy grass. They’re a solid value for the price, but skip them if you mow in dusty or debris-heavy conditions—opt for a thicker, coated blade instead.
