Bularie Notched High-Lift Mower Blades for 60" Decks — 3-Pack, Heat-Treated High-Carbon Steel

These Bularie notched high-lift mower blades are OEM-matching replacement blades made to restore bagging and discharge performance on 60-inch decks for compatible Cub Cadet, MTD and Troy-Bilt models.

If your lawn mower has lost suction, leaves large clippings behind, or shows uneven cutting, worn blades are often the cause. The Bularie 490-110-C187 / 742P05620 blades are heat-treated high-carbon steel replacements engineered to the same dimensions and mounting pattern as the factory parts, sold here as a convenient three-pack so you can replace multiple blades or keep spares on hand.

How do these blades improve bagging and discharge?

The notched high-lift profile increases airflow under the deck, which helps lift and move grass clippings into the chute or bagging system more efficiently. Compared with flat or low-lift blades, these provide stronger vacuuming action for cleaner collection.

• Notched high-lift shape for increased air movement and better bagging
• Heat-treated high-carbon steel resists wear and impact
• Edges designed to create a consistent cutting and lifting zone

Will these blades fit my mower model and mounting pattern?

Yes — these blades are made to directly replace OEM part numbers 490-110-C187, 742P05620, and 742-05620 and match the factory specifications. They use the standard six-point star center hole (1.012 inches) found on many 60" long-tail decks.

• Compatible with Cub Cadet ZT2-60 KW, ZT3-60 KW, ZT2-60 Fab, ZT3-60 Fab, Ultima ZT1-60, Ultima ZT2-60

What are the exact dimensions and material details?

Each blade in the three-pack measures precisely 20-9/16 inches long, 3-3/8 inches wide, and 0.126 inches thick. They are manufactured from heavy-duty, heat-treated high-carbon steel to balance cutting sharpness with impact resistance and wear life.

• Length: 20-9/16" (measured tip-to-tip)
• Width: 3-3/8"; Thickness: 0.126"
• Material: heat-treated high-carbon steel for durability

How should I install and maintain these blades for best results?

Installation is straightforward: remove the spindle bolt, replace the worn blade with the Bularie blade ensuring correct orientation, and torque to the manufacturer’s specification. Routine checks and maintenance keep performance optimal and extend blade life.

• Inspect blades frequently for dulling, bends, or cracks and replace when damaged
• Keep the deck clear of built-up debris to maintain airflow and cutting quality
• Follow mower manufacturer torque specs when tightening spindle hardware
