Mr Mower Parts 54" Ultra High-Lift Mower Blade Set 3-Pack for Cub Cadet/MTD Craftsman — 18-5/8" Diamond Center, .158" Thick

These are three Ultra High-Lift replacement blades engineered to restore a 54" deck's cutting performance on compatible Cub Cadet, MTD and Craftsman zero-turn and garden tractors.

If your mower's grass discharge or bagging performance has slipped, installing a matched set of high-lift blades can recover suction, improve clipping lift, and produce a cleaner, more even cut across the 54-inch deck. The Mr Mower Parts 742P05086 3-pack is shaped and sized to replace OEM 742-05086 blades: they fit "S" style spindle shafts with a diamond-shaped center hole and are built to withstand typical residential and light commercial use.

How do these Ultra High-Lift blades improve cut quality?

High-lift profiles generate stronger upward airflow beneath the deck, lifting grass upright so the blades shear cleanly rather than tearing. That yields a neater stripe, more uniform clippings for bagging, and reduced chance of ragged edges on dense lawns.

• Ultra High-Lift contour boosts suction for consistent grass lift.
• Precise edge geometry delivers cleaner shearing action.
• Three matched blades maintain balance and reduce vibration.

Will these blades fit my mower model and spindle type?

These blades replace OEM part numbers 742-05086 and 742P05086 and are designed for diamond center holes that pair with "S" shaped spindle hubs. They are compatible with a broad list of Cub Cadet, MTD, Troy-Bilt and Craftsman machines listed by model and series.

• Fits decks that require an 18-5/8" blade length with .158" thickness.
• Compatible with Enduro XT1-GT54, XT2-ST54, Ultima ZT1-54, ZT2-54 series.
• Works with models using the diamond-shaped center and "S" hub shaft.

How durable and easy to install are these replacement blades?

The blades are manufactured from hardened steel and finished to resist wear, giving reliable life under normal mowing conditions. Installation is straightforward: remove the old blades, align the diamond center, and torque the spindle nut to the manufacturer's specification.

• Constructed for long service life under residential use.
• Direct-fit replacement reduces retrofit steps and downtime.
• Pack of three keeps the deck balanced after replacement.

What size and specifications should I confirm before ordering?

Match blade length, center-hole shape, and hub style before purchase to ensure a correct fit. This 3-pack measures 18 5/8" overall with a diamond-shaped center hole and .158" thickness, designed for specific OEM-compatible spindles.

• Overall blade length: 18 5/8".
• Center hole: diamond shape for "S" style hubs.
• Blade thickness: .158" for stability and durability.

Who this product is for: These blades are intended for homeowners and small-property managers who own a 54" deck garden tractor or zero-turn from Cub Cadet, MTD, Troy-Bilt, or Craftsman that uses the 742-05086 style blade. They suit anyone looking to replace worn blades with a high-lift option for better bagging, improved stripe definition, and restored deck performance without modifying spindles or hardware.
