What It Is

The Grasscool 482877 Mulching Blade set is an aftermarket replacement designed for 48-inch deck zero-turn mowers from Bad Boy, Scag, and Hustler (Fastrak, Raptor SD). It replaces OEM part numbers 038-5000-00, 038-5350-0050, 481706, and 038 5350 00. These blades are intended for mulching—chopping clippings finely and recirculating them into the turf—not for bagging or side-discharge use.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: This set is for 48-inch decks only. It will not work on 42-inch, 52-inch, or 60-inch decks.
• Blade measurements: Each blade is approximately 18.5 inches long, 2.5 inches wide, with a 5-point star center hole. Measure your existing blade length and center hole shape to verify.
• Model check: Fits Bad Boy (ZT, Outlaw, MZ), Scag (Freedom Z, Turf Tiger, Cheetah), and Hustler (Fastrak, Raptor SD, Super Z) with 48-inch decks. If your mower uses a different OEM blade number (e.g., 038-5000-00 or 038-5350-0050), these are direct replacements.

Key Things to Know

• Installation: Easy bolt-on swap—use a torque wrench. Recommended torque is 70–90 ft-lbs. No modifications needed if your deck takes standard star-center blades.
• Mulching vs. standard: These are dedicated mulching blades. They have more lift and a curved wing design. If you bag or discharge, you’ll want standard or high-lift blades instead.
• Quality: Made from hardened steel with a powder coat. Some users report slight balance issues out of the box—check with a blade balancer before installing.
• Durability: Expect 25–50 hours of use before dulling, depending on debris and grass type. Sharpenable, but not intended for heavy-duty commercial use.

Should You Buy It

If you own a 48-inch Bad Boy, Scag, or Hustler zero-turn and want a budget-friendly mulching blade that performs well for residential or light commercial use, this is a solid pick. Avoid if you need bagging or side-discharge performance, or if you run a commercial operation that demands maximum blade life.
