Bularie High-Lift Mower Blades for 60-inch Decks — 3-Pack 21" Heat-Hardened Rust-Resistant

Bularie 3-pack high-lift mower blades replace OEM 04965000 and 310-042 for 60-inch decks, offering a heat-hardened 21" blade built to lift grass for a cleaner, more consistent cut.

These replacement blades are engineered for zero-turn and lawn tractor decks that require high-lift airflow to improve bagging and discharge performance. Each blade is heat hardened and factory-painted to resist warping and corrosion, and they match the size and center-hole specifications used by popular models like Ariens Ikon XL/ XD 60 and Gravely ZT series. Confirm your OEM part number and measure your current blade length before ordering to ensure fitment.

Will these blades fit my 60-inch mower deck?

They are designed specifically for decks listed to use the OEM part numbers 04965000 and 310-042 and are intended for 60-inch cutting decks. Always verify by checking the existing blade’s printed part number and measuring length, width, thickness, and center hole diameter to avoid mismatches.

• Blade length: 21" (measure from tip to tip).
• Blade width: 2.5"; thickness: 0.19".
• Center hole: 5/8" round—confirm your spindle bolt size.
• Compatible models: Ariens Ikon XL/ XD 60; Gravely ZT XL 60, ZT XL 60 CARB, ZTX 60 (check your mower manual).

How does the high-lift design affect cutting and bagging?

High-lift blades create stronger upward airflow beneath the deck to elevate grass blades before cutting, which improves cut consistency and helps move clippings into the discharge or bagging system. This design is especially useful when mowing taller or damp grass, as it reduces clumping and helps prevent buildup inside the deck.

• Stronger suction for improved bagging and side discharge.
• Cleaner trim lines and more uniform clippings across the deck width.
• Reduced thatch accumulation under typical mowing conditions.

What materials and treatments ensure durability?

These blades are manufactured from heavy-duty steel and undergo heat treatment to harden the cutting edge, helping them resist deformation at high RPMs. A factory paint finish adds a corrosion-resistant layer to protect the metal during storage and in normal use.

• Heat-hardened steel construction to reduce bending and edge failure.
• Factory paint for rust resistance and longer service life.
• Sold in a 3-pack so you can replace all deck blades at once for balanced performance.

How should I install and check these blades for safe operation?

Install blades with the cutting edge facing the ground, and torque fasteners to the mower manufacturer’s specification. After mounting, manually rotate the blade assembly through 360 degrees to confirm there is adequate clearance from deck components and that nothing interferes with rotation.

• Always disconnect spark plug before handling blades.
• Check blade orientation: cutting edge down toward grass.
• Rotate by hand to verify deck clearance and avoid contact points.

Who is this for: This 3-pack is suited to homeowners and landscape professionals who operate 60-inch mowing decks and need a direct-fit, high-lift replacement for OEM 04965000 / 310-042. Choose these blades if you want improved airflow for bagging or discharge, heat-treated durability for heavy-duty mowing, and matching OEM dimensions for straightforward installation. Remember to double-check measurements and part numbers to ensure proper compatibility before purchase.
