SCBHWJ High-Lift Replacement Blades for John Deere 48" Deck — 3-Pack, 7-Point Star Fit, Heat-Treated

SCBHWJ three-piece high-lift blade set replaces John Deere GY20852/GX21784/AM137757 to restore cutting performance on 48-inch decks.

If your John Deere lawn tractor is leaving uneven clippings, tearing grass, or struggling with bagging and side discharge, worn blades are often the cause. These SCBHWJ replacement blades are precision-cut and heat-treated to match the fit and function of the OEM part numbers for many 48" Deere decks. Each blade measures 17 1/8" long, 2 3/4" wide, 0.1875" thick and uses the common 7-point star center hole, so installation is straightforward for most homeowners and service techs.

Will these blades fit my John Deere 48" deck?

Yes—these blades are designed to replace the listed OEM part numbers and fit a wide range of John Deere models with 48" decks. Confirm your tractor’s deck size and current blade hole pattern before ordering.

How do these high-lift blades affect cutting and bagging?

High-lift blades create stronger upward airflow beneath the deck, improving lift of grass blades and enabling cleaner cuts and more efficient bagging. They help move clippings into the chute and bagger more effectively than low-profile blades.

• Enhanced suction for improved bagging performance
• Cleaner, more even cut pattern across the 48" swath
• Designed to reduce clumping and side discharge residue
• Heat-treated edge for longer wear between sharpenings

The set includes three identical blades manufactured to match OEM dimensions and hole pattern. Thickness and edge profile are chosen to balance durability and cutting performance for residential use.

• Length: 17 1/8" (approx.) to match deck radius
• Width: 2 3/4" for proper blade sweep and clearance
• Thickness: 0.1875" (3/16") for strength and stability
