04265400 Notched High Lift Blades for 42" Mower Deck, Compatible with Gravely ZT 42 Zero Turn A-riens Zoom Series Lawn Mower, Replace 1134-9210-01, 3 Pack

What It Is

This is a 3-pack of notched high-lift mower blades designed for 42-inch cutting decks, specifically for Gravely ZT 42 zero-turn mowers and A-riens Zoom series mowers. The high-lift design creates stronger airflow to improve grass clipping discharge and bagging performance, making it ideal for mulching or collecting in dense or wet grass.

Fitment & Compatibility

Before buying, verify your deck is exactly 42 inches (measured blade tip to tip). These replace OEM part 1134-9210-01 and fit Gravely ZT 42 models and A-riens Zoom series (e.g., ZT 42, ZT 42L, Zoom 42). Check the blade length (typically 21 inches center-to-center) and center hole size (usually 1 inch). Also confirm the notch pattern matches your spindle—some older decks may need a different offset. Measure your existing blade’s thickness (usually 0.25 inches) and ensure these match.

Key Things to Know

• Quality: Most users find them durable enough for residential use, but some report balance issues out of the box—check with a blade balancer before install.
• Installation: Easy swap with a socket wrench and blade removal tool; torque to 70-90 ft-lbs. Use thread locker on bolts to prevent loosening.
• Gotchas: The high-lift design can cause more vibration on uneven decks or if not balanced. Notched blades may leave uncut strips if deck is not level.
• Performance: Improved bagging and discharge, but may wear faster than OEM in sandy or rocky soil.

Should You Buy It

If you own a Gravely ZT 42 or A-riens Zoom 42 and need a budget-friendly replacement that boosts bagging or discharge performance, this 3-pack is a solid value. However, if you have an older deck or prioritize long life over lift, consider OEM or a standard blade instead.
