Aeagle 42 Inch High Lift Blade for Ariens Zoom 915159 915161 915171 915233 915323 Gravely ZT 42'' Deck Zero Turn Lawn Mower Replace 04265400 1134-9210-01, 3 Pack (Black)

What It Is

This is a set of three 42-inch high-lift mower blades designed for Ariens Zoom and Gravely ZT zero-turn mowers with 42-inch cutting decks. High-lift blades create stronger upward airflow for better grass discharge and bagging performance, making them ideal for tall or wet grass.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck—this set will not fit 36-inch or 48-inch decks. Compatible with Ariens Zoom models 915159, 915161, 915171, 915233, 915323 and Gravely ZT models with a 42-inch deck. Replaces OEM part numbers 04265400 and 1134-9210-01. Measure your existing blade’s center hole diameter (typically 7/8-inch or 1-inch) and ensure it matches; these blades have a 7/8-inch center hole. Check blade thickness (0.25 inches) and overall length (42 inches end to end) against your current blades.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool; no special skills needed. Always disconnect the spark plug before working.
• High-lift design: Produces more lift than standard blades, which improves bagging but may increase engine load slightly. Not ideal for dusty or sandy conditions as they can stir up debris.
• Build quality: 4.6 stars from 58 reviews suggests good durability, but inspect for sharpness out of the box—some users report needing to sharpen edges.
• Common gotcha: These are aftermarket, not OEM. Fitment is generally accurate, but double-check the center hole size; a mismatched hole will prevent proper installation.

Should You Buy It

If you own an Ariens Zoom or Gravely ZT with a 42-inch deck and want better grass lift for bagging or mulching, this is a solid, budget-friendly aftermarket option. It’s not for heavy-duty commercial use or sandy lawns, but for residential mowing, it offers reliable performance at roughly half the cost of OEM blades.
