Aeagle 42" High-Lift Replacement Mower Blades for John Deere – 7-Point Star Center, 3-Pack

Aeagle AM141034 are high-lift 42-inch replacement mower blades with a 7-point star center hole, sold as a 3-pack to fit many John Deere 42" mower decks and zero-turn models.

If your John Deere riding mower or residential zero-turn uses a 42" deck and a 7-point star center mounting, these Aeagle high-lift blades are designed to restore cutting performance and improve clipping handling. They reproduce the factory-compatible AM141034 profile and fit a long list of John Deere models and OEM part cross-references. Built to lift grass for cleaner cuts while discharging efficiently, these blades work for both bagging and side-discharge setups.

How do these blades fit my John Deere mower?

These Aeagle blades use a 7-point star center hole — confirm your current blade’s center matches before buying. They are sold as three identical blades sized to serve a 42" deck that typically uses 21-1/4" single-blade halves or paired blades in multi-blade spindles.

• Mounting: 7-point star center hole (not circular hubs).
• Compatibility: Fits many John Deere 100, 200, 300, X300 series and select Z-series zero-turn decks.
• Cross-reference: Replaces AM137327/AM141031/AM141032/AM141034 and similar OEM numbers.
• Measure to confirm: blade length 21 1/4", width 2-5/8", thickness about 1/6".

What cutting performance can I expect from a high-lift 2-in-1 blade?

These blades are classified as high-lift and serve a 2-in-1 purpose: they create upward airflow to stand grass upright for a precise cut while still feeding clippings toward the discharge or bagging system. Expect improved bagging performance and a narrower striping pattern versus low-lift designs.

• Airflow: Moderate upward lift for cleaner, even cuts.
• Bagging & discharge: Balanced design lets you collect clippings or side-discharge efficiently.
• Edge maintenance: Cutting faces arrive painted for protection and can be resharpened when dull.
• Material resilience: Stamped steel construction resists impact and bends under normal use.

How do I install and maintain these replacement blades safely?

Installation follows typical mower blade replacement steps: disconnect spark plug, block wheels, support the deck, remove blade hardware, and torque new blades to the manufacturer’s spec using the correct orientation. Keep edges covered with the protective coating until first use and resharpen as needed rather than grinding aggressively.

• Safety first: Always disconnect spark and stabilize the tractor before starting.
• Orientation: Install with cutting edge facing the direction of rotation and mower deck oriented correctly.
• Retention: Use original hardware and torque to factory specifications.
• Sharpening: Refinish edges if nicked; protective paint wears off in use.

Which deck sizes and models are covered by these blades?

These blades are made for 42" compatible decks and appear on a wide array of John Deere model lines, including many 100-series tractors, X300 select series, and residential Z-turn mowers listed in the product references. They also cross to OEM part numbers used across earlier model years.

• Deck size: 42" (compatible with 42" mower decks and associated spindles).
• Models: Includes D100, D110, D125, E110, LA105/115/135, LT150, S130, X300 series, Z225, Z235 and many 100/200 series tractors.
• OEM cross-refs: AM137327, AM141031, AM141034, GX22151 and similar numbers.
• Check: Verify your blade’s center hole shape and blade length before ordering.
