Grasscool 5101755 5101755s Blades Compatible with Ferris Scag Turf Tiger Bad Boy Simplicity 61" Zero Turn Mower Replace for 5020842 48111 481708

What It Is

This is a set of three 61-inch replacement blades designed for commercial-grade zero-turn mowers. They are compatible with Ferris, Scag Turf Tiger, Bad Boy, and Simplicity models, making them suitable for heavy-duty residential or professional mowing.

Fitment & Compatibility

Before buying, check that your mower deck is exactly 61 inches—these blades are specifically sized for that width. Confirm your existing OEM part numbers: this set replaces Ferris 5020842, Scag 48111, and Bad Boy/Simplicity 481708. Measure blade length (should be ~20.5 inches each), center hole diameter (typically 1 inch), and thickness (about 0.25 inches). Verify your mower’s spindle pattern matches the three-blade design. Aftermarket fit may vary slightly, so compare the blade’s mounting holes and offset to your originals.

Key Things to Know

• Quality: Grasscool blades are heat-treated and coated for durability, but may not match OEM steel hardness—expect slightly faster wear under heavy use.
• Installation: Straightforward if you have a socket set and jack stands. Torque spindle bolts to 70-90 ft-lbs. Always use new blade bolts if recommended.
• Common gotcha: Some users report the blades need slight balancing out of the box. Check with a balancer before installing to avoid vibration.
• Offset check: Ensure the blade’s lift angle matches your deck design—wrong offset can reduce cut quality or cause scalping.

Should You Buy It

If you need an affordable, compatible set for a 61-inch zero-turn and don’t mind a minor balancing check, this is a solid value. It’s best for budget-conscious homeowners or light commercial use; for heavy daily mowing on rough terrain, stick with OEM blades for longer life.
