GICOOL 942-04053C Cub Cadet 50 Inch Mower Blades for Zero Turn Riding Mower RZT50 LT1050 SLT1550 LGT1050 Replace 742-04053 942-04056 (6 Point Star Mounting Hole)

What It Is

This is a 50-inch set of three GICOOL aftermarket mower blades designed for Cub Cadet zero-turn and lawn tractors with a 6-point star mounting hole. They’re meant for medium-to-large residential mowing decks.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: These are for 50-inch cutting decks only. Measure your deck width to be sure.
• Mounting hole: The 6-point star pattern fits Cub Cadet spindles using OEM part numbers 742-04053, 942-04053, or 942-04056. If your spindle uses a different hole shape (e.g., oval or keyhole), these won’t work.
• Model match: Compatible with Cub Cadet RZT50, LT1050, SLT1550, LGT1050, and similar models. Check your owner’s manual or existing blade part number to verify.

These are aftermarket blades, not OEM Cub Cadet. They’re a direct replacement in size and mounting but may differ slightly in steel thickness or coating.

Key Things to Know

• Installation difficulty: Easy – takes about 15-20 minutes with a socket wrench and a block of wood to lock the blade. No special tools needed.
• Quality: Made from heat-treated steel. Expect decent durability for residential use, but may dull faster than OEM or premium aftermarket blades if you hit rocks or roots.
• Common gotcha: The center hole is exactly 6-point star, but some older Cub Cadet spindles may have worn star points. Check that the blade slides on smoothly without forcing it.
• Lift and cut: These have a moderate lift design. Fine for flat grass; less ideal for bagging thick or wet grass compared to high-lift blades.

Should You Buy It

If you own a 50-inch Cub Cadet zero-turn or lawn tractor with a 6-point star spindle and need a budget-friendly set that gets the job done for residential mowing, this is a solid pick. It’s not for heavy commercial use or rough terrain, but for the price, it’s a reliable replacement.
