Chway 48-inch 3-Pack Mulching Blades — 7-Point Star, Heat-Treated & Balanced

High-strength Chway GY20852 7-point star mulching blades—three 48" replacement blades engineered to fit mowers with a 7-point star spindle and deliver reliable mulching and bagging performance.

If your John Deere or compatible 48" deck mower needs durable, correctly patterned replacement blades, this 3-pack from Chway is built to match OEM fitments and cutting characteristics for many 48-inch models. Each blade is heat-treated, factory-straightened and dynamically balanced to reduce vibration, resist impact, and keep cut quality steady across uneven turf. These are mulching high-lift blades shaped to improve clipping circulation so clippings are finely chopped and returned to the lawn as organic material.

How do these blades match my mower's spindle pattern?

These Chway blades use a 7-point star center hole and will only install on 48" decks that accept a 7-point star spindle. They will not fit round or other shaped center holes, so confirming the spindle shape before purchase prevents fitment issues. Compare your old blade’s center hole or check OEM part numbers to ensure compatibility.

• Center hole: 7-point star only
• Designed for 48" decks using star-pattern spindles
• Compare old blade or OEM part number (e.g., GY20852, GX21784)

What John Deere models are these blades compatible with?

Chway lists broad compatibility across several John Deere series that use 48" decks with a 7-point star spindle. These blades are often used as replacements for common OEM numbers and fit many 100, E, LA, S, X series and some ZTrak models when the deck and spindle match. Always cross-check your mower’s model and deck configuration before ordering.

• Fits many John Deere 100 Series and D-series 48" tractors
• Compatible with E-series, LA-series and S-series 48" decks
• Works on selected X Series and ZTrak zero-turn mowers with 48" decks

What are the construction and performance features?

Each blade is made from heat-treated high-strength steel for hardness and impact resistance, then ground and balanced at the factory to minimize vibration. The mulching profile and high-lift curvature boost airflow and chop clippings more finely so they can feed back into the lawn as mulch while still providing strong bagging when required.

• Material: heat-treated, high-strength steel for durability
• Dimensions: 17" length x 2 5/8" width x 0.16" thickness
• Lift: 1 1/8" high-lift profile for improved airflow
• Rust-resistant coating for safe handling during installation

Will these blades handle rough or weedy lawns?

The hardened steel construction and balanced finish help the blades resist impacts from roots, stones and dense weeds better than untreated metal. While no blade is indestructible, these are engineered for tougher cutting conditions and to keep an even cut across uneven terrain when properly installed and maintained.

• Heat treatment improves toughness for rough conditions
• Factory straightened to reduce wobble and blade wear
• Balanced to limit vibration and protect spindle components

Who is this for: Homeowners and pros who own a 48" deck mower with a 7-point star spindle and need a reliable mulching/high-lift blade replacement in a three-blade set. If you use a John Deere 48" deck or a compatible mower and seek OEM-equivalent parts (matching listed numbers or spindle pattern), these Chway blades provide a cost-effective way to restore cutting performance, encourage healthier clippings return, and keep vibration low. Do verify spindle shape and part compatibility before ordering to ensure a correct fit.
