BCQNXX High-Lift Replacement Mower Blade for 42" Deck — 2-Pack, Heavy-Duty Steel, Powder-Coated

If your mower is leaving uneven clippings, struggling with tall or thick grass, or you need a direct-fit spare set, these two high-lift blades provide a durable, OEM-replacement option. Machined to match the critical dimensions of John Deere part numbers AM141034, AM141032, M154062, AM137327 and M154061, the BCQNXX blades are built from thick steel with a powder-coated finish to resist corrosion and maintain edge life.

Will these blades fit my tractor or zero-turn mower?

These blades are made to fit a long list of John Deere and select Sabre and EUROPRO models that use the AM141034 family of parts. Because fit depends on exact deck configuration and mounting pattern, cross-reference your original OEM part number or compare the blade’s dimensions to your old blade before ordering.

• Length: 21-1/4"; width: 2-3/4"; thickness: 0.157"
• Center hole diameter: 7/8" with 7-point star pattern
• Compatible with many John Deere D, E, L, LT, S, X and Z Series listed by OEM
• Also fits numerous Sabre and EUROPRO models specified under AM141034 cross-reference

How do these high-lift blades change cutting performance?

High-lift blades generate stronger upward airflow beneath the deck, which helps lift grass upright for a cleaner, more even cut and improved bagging performance. They work especially well when mowing taller turf or denser, damp grass where standard blades can leave clumps or tear rather than slice.

• Sharper upward suction improves grass stand and bag fill
• Extended cutting edge increases cutting coverage per pass
• Good for both bagging and discharge on compatible decks
• Two blades included to service both sides of a 42" deck

What are the materials and build features that affect durability?

Each blade is fabricated from heavy-gauge steel engineered to resist bending under load and to hold an edge longer than thinner aftermarket alternatives. The powder-coat finish reduces surface rust, and the thicker cross-section helps the blade withstand impacts from small debris without catastrophic failure.

• Heavy-duty steel construction for strength and longevity
• Powder-coated surface to slow corrosion
• 0.157" thickness to resist flexing and premature wear
• Balanced shape and mounting pattern for consistent rotation

How do I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark, remove the old blade(s), confirm orientation and torque the blade bolt to your mower manufacturer’s specification. Routine inspection for nicks or bends and periodic sharpening will extend blade life and sustain cutting quality.

• Always disconnect the mower spark plug before servicing
• Match cutting edge orientation with the original blade (high-lift face up)
• Check and tighten blade bolts to OEM torque values
• Sharpen and balance blades as needed instead of replacing immediately

Who is this for: BCQNXX AM141034 high-lift blades are intended for owners of 42-inch residential and small commercial John Deere and compatible Sabre/EUROPRO decks who need a robust, OEM-dimension replacement. Choose this two-pack if you want thicker, powder-coated steel blades for improved bagging, cleaner cuts in tall or dense grass, or a direct substitute for the listed John Deere part numbers. If you’re unsure about fit, compare the blade length, hole size and star-mount pattern with your current blade or consult your mower’s parts list before purchasing.
