Bularie 42-inch High-Lift Mower Blades 2-Pack — 7-Point Star Fit, Carbon-Boron Steel for Cleaner Bagging

These are Bularie high-lift, bagging replacement blades engineered to fit John Deere 42-inch decks with a 7-point star center hole, sold as a 2-pack for efficient bagging and clean cuts.

If your mower’s current blades leave uneven clippings, clog the deck while bagging, or have worn-down edges, switching to a properly sized high-lift blade restores airflow and cutting performance. Bularie’s AM141034-compatible blades are manufactured from carbon-boron steel for extra hardness and edge retention, and they match many OEM numbers so you can be confident about fit and function.

Will these blades fit my John Deere mower?

These blades are designed specifically for 42-inch John Deere decks that use a 7-point star center mount. They directly replace many OEM and aftermarket part numbers, so cross-referencing your mower’s part number helps confirm compatibility.

• Replaces AM141034, AM137329, M154062 and other listed OEM numbers
• Compatible with D100–D130, E100–E130, L100–LA135, LT160/180, S100–S240, X110–X310, Z225/Z235 ranges
• Measures approximately 21-1/2" long for correct deck clearance
• Requires a 7-point star center hole — verify before purchase

How do these blades improve bagging and mulching?

The blades use a high-lift, bagging profile to create stronger upward airflow under the deck so grass is lifted and expelled into collection bags more reliably. That airflow reduces clumping and keeps the cutting chamber clearer, which improves overall bagging efficiency and produces a more even discharge.

• High-lift aerodynamic shape increases suction under the deck
• Seven-point star mount keeps blade centered and secure
• Sharp, hardened cutting edge produces cleaner cuts and fewer ragged clippings
• Works for bagging and side discharge depending on deck setup

What are these blades made from, and how long will they last?

Bularie blades are made from a carbon-boron steel blend that balances toughness and edge retention, helping them stay sharp longer than standard mild-steel blades. Proper use and occasional sharpening will extend service life, while the solid construction resists chips and breaks during normal mowing.

• Carbon-boron steel for enhanced hardness and durability
• Factory-ground edges for immediate cutting performance
• Reduced deck clogging helps minimize wear from heavy loads
• Sold in a 2-pack so you can replace both blades on a typical 42" deck at once

How easy is installation and what should I check before replacing blades?

Installation is straightforward and tool-free only in the sense of correct fit — you’ll still use basic hand tools to remove and install blade bolts. Confirm the 7-point star center hole and the OEM number match your mower before swapping blades to ensure a precise fit and safe operation.

• Confirm center hole shape is 7-point star on your spindle
• Use proper torque on blade bolts and follow mower manufacturer safety steps
• Replace blades as a matched pair for even deck balance
• Inspect for clearance and retighten after first hour of use

Who is this for: These blades are for John Deere owners and maintenance professionals who need a reliable OEM-compatible replacement for 42-inch decks that improves bagging performance and edge life. They suit users who want durable, high-lift blades made from harder steel, and anyone replacing both blades on their riding mower to restore balanced cutting and better collection.
