5101755S Lawn Mower High Lift Blades for Ferris Scag Bad Boy 61 Inch Mower Decks - Heavy Duty Blade Replaces 5101755 5020842 20842S 481712 A48111 481708 482879-6 Pack

What It Is

This is a set of six high-lift mower blades designed for 61-inch commercial zero-turn mowers. The high-lift profile increases airflow for better grass clipping discharge and bagging performance, making them suited for thick or wet grass conditions.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This 6-pack fits only 61-inch cutting decks. Measure your deck width if unsure.
• Brand/model: Fits Ferris (IS3100Z, IS3200Z, IS4500Z), Scag (V-Ride, Cheetah, Turf Tiger, Wildcat), and Bad Boy (Outlaw, ZT Elite) – but check your specific model year. Cross-reference with OEM numbers: 5101755, 5020842, 20842S, 481712, A48111, 481708, 482879.
• Measurements: Each blade is 20.5 inches long, with a 1-inch center hole and 1/4-inch offset thickness. Confirm these dimensions match your spindle.

If your mower uses a different center hole size (e.g., 5/8-inch or 7/16-inch), these won’t fit.

Key Things to Know

• Lift & discharge: High-lift blades create strong suction; great for bagging or side discharge, but they increase engine load and can cause clumping in very dry, dusty conditions.
• Installation: Easy – just a socket and torque wrench. Use a blade removal tool to prevent spinning. Torque to 70-90 ft-lbs (check your manual).
• Durability: Aftermarket steel; not as thick as OEM heavy-duty options. Expect faster dulling if you mow sandy or rocky terrain. Balance each blade after install.
• Price vs value: At ~$9.50 per blade, this is budget-friendly for a full deck replacement. But read reviews – some users report premature wear or balance issues.

Should You Buy It

If you own a 61-inch Ferris, Scag, or Bad Boy zero-turn and need a low-cost set of high-lift blades for bagging or heavy grass, this is a reasonable buy. Skip it if you mow abrasive soil or want OEM-grade longevity – spend more on genuine Ferris/Scag blades instead.
