ZALANA 42-inch High-Lift Mower Blades (2-Pack), 7-Point Star Center, Heavy-Gauge Steel

ZALANA AM141034 is a heavy-duty two-pack of high-lift replacement blades engineered to restore cutting performance on 42-inch decks that use the John Deere AM141034-style 7-point star mounting.

These replacement blades are built to match common John Deere OEM part shapes and dimensions so you can swap them in without modifying your deck. Each blade is high-lift style for stronger suction and cleaner bagging on lawns that need improved clippings lift, and the two-blade pack lets you service both sides of a 42" deck or keep a spare on hand. Dimensions and the 7-point (7/8") star center hole are sized to fit many D, LA, L, LT, X and Z series machines—confirm your original part number before ordering.

Will these blades fit my John Deere 42" deck?

Measure your original blade to confirm compatibility: length, width, thickness, and the 7-point center hole are critical. ZALANA lists the common John Deere OEM numbers these blades replace, but physical comparison is the safest check.

• Center hole: 7-point star (7/8")
• Length: 21-1/4" (end-to-end)
• Width: 2-5/8"
• Thickness: 0.177"; deck size: 42 inches

How does high-lift design affect mowing and bagging?

High-lift blades generate stronger upward airflow beneath the deck, which lifts grass clippings quickly for a cleaner cut and improved movement into the chute or bagger. This is helpful if you use a bagger frequently or need a tidier discharge in taller or denser turf.

• Stronger suction for better bag fill and discharge
• Cleaner cut height due to improved vertical lift
• Works well on thicker, damp, or heavier-growth lawns

What materials and build details should I expect?

The blades are made from heavy-gauge steel for durability and resistance to bending under normal mowing conditions. They are pre-punched with the 7-point center pattern and balanced at the factory to reduce vibration when installed correctly.

• Heavy-duty steel construction for long service life
• Pre-drilled 7-point star center for direct fit
• Balanced in pairs to minimize vibration and wear

How do I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect power, remove the spindle hardware, swap blades while noting orientation, torque bolts to spec, and then check balance and clearance. Regular sharpening and inspecting for damage will keep the blades cutting efficiently.

• Disconnect the battery or spark plug before service
• Use manufacturer torque specs for mounting bolts
• Inspect blades for cracks and sharpen as needed

Who is this for: Homeowners and lawn care enthusiasts with John Deere or compatible 42" deck mowers who need a reliable high-lift replacement blade set. This two-pack suits users who want to replace both blades at once, keep a spare for quick swaps, or restore better bagging and lift performance on medium to large residential lawns. Always verify your original part number, blade dimensions, and center-hole pattern before ordering to ensure an exact fit.
