8TEN LawnRAZOR Mower Blade for Ariens Zoom Gravely ZT Zero Turn 42 Inch Deck 04265400 (Notched High-Lift) 3 Pack

What It Is

This 8TEN LawnRAZOR notched high-lift blade (3-pack) is designed for Ariens Zoom and Gravely ZT zero-turn mowers with a 42-inch cutting deck. The high-lift design improves grass discharge and bagging performance, making it ideal for thick or wet grass.

Fitment & Compatibility

• Deck size: 42-inch deck only. Measure your blade length; these are typically 18 inches long with a 5-point star center hole.
• OEM cross-reference: Replaces Ariens/Gravely part number 04265400. Confirm your deck model (e.g., Zoom 1542, ZT 42) before buying.
• Aftermarket note: Notched blades fit specific spindle designs—check that your deck uses a notched (not smooth) center hole. The 5-point star pattern is common on Ariens/Gravely.
• Measurement check: Verify blade length, width, and center hole shape against your current blade. Use a tape measure and compare to the OEM spec.

Key Things to Know

• High-lift performance: Great for bagging and side discharge, but creates more drag and noise than standard blades. May strain the engine in tall, wet grass.
• Installation: Easy swap with a socket and torque wrench (recommended 70-90 ft-lbs). Use thread locker on spindle bolts to prevent loosening.
• Sharpness: Come sharp out of the box, but dull faster than OEM blades in sandy or rocky soil. Expect to sharpen after 10-15 hours of use.
• Balance check: Always balance new blades before mounting to avoid vibration and spindle wear. A simple blade balancer is cheap insurance.

Should You Buy It

If you own an Ariens Zoom or Gravely ZT with a 42-inch deck, need to replace dull or damaged blades, and want improved bagging or discharge for thick grass, this 3-pack is a solid value. It’s not for decks smaller or larger than 42 inches, or for mulching-only setups.
