Grasscool ZT1 50" High-Lift 6-Point Star Mower Blades — 17-1/4" x 5/32" for Cub Cadet 50" Decks, Bagging/Side-Discharge

If your Cub Cadet, Troy-Bilt, Craftsman or similar lawn tractor uses a 50-inch cutting deck and a 6-point star center mounting, the Grasscool ZT1 blades are a direct-fit replacement designed to restore cutting efficiency and power for bagging or side-discharge setups. Each blade is manufactured with high-lift geometry to send grass clippings upward into a bagging system or mulching chamber while matching OEM dimensions for fast installation.

How do I confirm these blades will fit my mower?

Before ordering, check the shape of your blade's center hole — the Grasscool ZT1 replacement uses a 6-point star (5/8"). If your current blades have an S-shaped or different center, these will not align and you’ll need a different MPN.

• Center hole: 6-point star (5/8").
• Blade length: 17-1/4" overall.
• Thickness: 5/32" for factory-strength durability.
• Compatible with many Cub Cadet/MTD/Troy-Bilt 50" decks listed in the vehicle fitment.

What cutting and deck performance should I expect?

These are high-lift blades built to create strong airflow for bagging and efficient clippings evacuation. They re-establish the suction needed for tidy collection and a cleaner cut line along the mower path.

• Air lift height: 1-3/16" to promote robust upward suction.
• Cutting edge length: 5-1/8" for a consistent turf finish.
• Suitable for both bagging and side-discharge on 50" decks.
• Painted finish protects blades from corrosion during handling and storage.

How do these compare to OEM part numbers and alternatives?

Grasscool blades match the key OEM measurements for part numbers like 742-05052A and 942-05052A while offering the same high-lift profile. They are a cost-effective aftermarket option when you need like-for-like replacement geometry and fit without compromise.

• Replaces Cub Cadet/MTD/Troy-Bilt part numbers 742-05052A, 942-05052A and equivalents.
• Meets dimensional specs expected by original equipment designers.
• Intended for 34" and 50" compatible decks where a 6-point star center is used.
• Not compatible with S-shaped center hole blades (use MPN 742-05094 for S-shaped).

What are the installation and maintenance details?

Installation follows standard blade-replacement procedures: remove fasteners, align the star hole, and torque to your mower manufacturer’s spec. The protective paint can be left in place; it wears off quickly once the blade is in use and helps prevent surface rust during storage.

• Do not remove protective paint before first use; it dissipates after a few minutes of operation.
• Follow mower manual for correct bolt torque and rotation orientation.
• Inspect blades periodically for nicks, bends or excessive wear and replace as needed.
• Keep blades balanced for vibration-free operation and longer spindle life.
