8TEN Spindle High Lift Blade Kit 50 inch Cut Deck for Cub Cadet MTD RZT L50 S50 LX50 SX50 XT1-GT50 ZT1-50 G8200 G8300

What It Is

This is a complete spindle-mounted high-lift blade kit for 50-inch cut decks, designed for Cub Cadet and MTD zero-turn and lawn tractors. It replaces the stock blades to improve grass lift and discharge, especially in tall or damp conditions.

Fitment & Compatibility

• Deck size: Only for 50-inch decks (not 46", 48", or 54").
• Model match: Fits Cub Cadet RZT L50, S50, LX50, SX50, XT1-GT50, ZT1-50, plus G8200, G8300. Also fits MTD equivalents with a 50" deck.
• OEM vs aftermarket: This is a direct OEM replacement for Cub Cadet/MTD spindle assemblies (part numbers 942-0762, 742-0762, and 942-0762A). No modifications needed.
• Measurements: Each blade is approximately 16.25" long, 2.5" wide, with a 0.5" center hole and 0.5" offset. Verify your spindle pattern matches (3-hole, 3.5" center-to-center).

Key Things to Know

• Higher lift = better discharge, but more power draw. High-lift blades throw clippings farther but require more engine power. Not ideal for underpowered or older decks.
• Installation is straightforward. Remove the spindle nut, swap the blade, and torque to 70-80 ft-lbs. No special tools beyond a socket and torque wrench.
• Expect slightly more noise and wear. The aggressive lift profile creates more wind noise and can accelerate blade dulling in sandy or dusty conditions.
• Check deck level before installing. Uneven decks cause scalping and poor cut quality—high-lift blades amplify this.

Should You Buy It

Buy this kit if you have a 50-inch Cub Cadet or MTD tractor and want noticeably better grass lift, bagging, or side-discharge performance in thick or wet grass. Skip it if your engine is under 20 HP, your deck is worn, or you prefer standard lift blades for quieter, lower-maintenance mowing.
