ACEBRI Mower Blades 50 inch for Cub Cadet ZT1 ZT2 XT1 LT50 ZT1 50 RZT 50 ZT2 50 Ultima blades for Troy Bilt for Cub Cadet 942-05052A 742-05052 XT2 L50 LX50 S50 GT50, 6 Pack (6 Point Star)

What It Is

This is a 6-pack of aftermarket 50-inch mower blades designed for select Cub Cadet, Troy Bilt, and compatible lawn tractors with a 6-point star center hole. They are intended for mulching or bagging on residential or light commercial zero-turn and lawn tractor decks.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch cutting deck and a 6-point star spindle mount (not a 5-point star or oval hole). This set fits Cub Cadet models: ZT1 50, ZT2 50, XT1 LT50, XT2 L50, LX50, S50, GT50, RZT 50, and Ultima ZT1 50. Also fits Troy Bilt models using OEM part numbers 942-05052A or 742-05052. Measure your existing blade length—these are 50-inch deck blades (typically ~16.5–17.5 inches each, but always verify total set length matches your deck). Check spindle nut size (usually 5/8" or 3/4") to ensure you have the right socket.

Key Things to Know

• Quality vs OEM: Aftermarket blades at this price point may be slightly thinner or less balanced than OEM Cub Cadet blades. Expect adequate performance for residential use, but not heavy commercial duty.
• Installation: Requires lifting the mower safely, removing the deck, and using a torque wrench (recommended 70–90 ft-lbs). Blades come unsharpened—you may need to sharpen before first use.
• Balance check: Aftermarket blades can be unbalanced out of the box. Test each blade on a balancer before installing to avoid vibration and spindle wear.
• Common gotcha: The 6-point star center hole must align perfectly with your spindle. If your deck uses a 5-point star or a keyed hole, these will not fit.

Should You Buy It

If you own a compatible 50-inch Cub Cadet or Troy Bilt with a 6-point star spindle and need a budget-friendly 6-pack for regular seasonal replacements, this set offers good value for residential mowing. For commercial use or if you prioritize long blade life and perfect balance, stick with OEM Cub Cadet blades.
