5101755S 482879 Lawn Mower Blades Compatible with scag 61 inch Mower Blades, Ferris 61 inch Mower Blades, Bad boy 61 inch Mower Blades, Replace 5020842S, 15208425S, 48111, 481708 Blades

What It Is

This is a set of three aftermarket 61-inch lawn mower blades designed for zero-turn mowers from Scag, Ferris, and Bad Boy. They replace OEM part numbers 5020842S, 15208425S, 48111, and 481708, and are intended for cutting grass on commercial or residential zero-turn mowers with 61-inch decks.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 61 inches (not 60 or 72). These blades fit Scag 61-inch decks (e.g., Cheetah, Turf Tiger, Wildcat), Ferris 61-inch decks (e.g., IS 3200Z, IS 5100Z), and Bad Boy 61-inch decks (e.g., Outlaw, ZT). Measure your existing blade length, width, and center hole diameter (typically 7/8" to 1"). Also check the blade thickness—these are usually 0.25 inches. Cross-reference your OEM part number: if you have 5020842S, 15208425S, 48111, or 481708, these will match. Do not assume compatibility based on brand alone—some 61-inch decks use different blade patterns.

Key Things to Know

• Quality: Aftermarket blades; may not match OEM steel hardness or coating. Expect similar cutting performance but potentially shorter lifespan under heavy use.
• Installation: Easy if you have a socket set and jack/ramps. Always disconnect the spark plug and wear gloves. Torque blade bolts to 70–90 ft-lbs.
• Common gotcha: These blades may have a different air-lift design than OEM, affecting discharge or bagging. Check if your deck requires high-lift, low-lift, or mulching blades—this set is typically medium-lift.
• Balance: Aftermarket blades often need balancing before installation. Use a blade balancer to avoid vibration and spindle wear.

Should You Buy It

Buy this set if you need a budget-friendly replacement for Scag, Ferris, or Bad Boy 61-inch zero-turn mowers and you’re comfortable with standard aftermarket trade-offs (slightly less durability, potential balancing). Avoid if you need OEM-grade steel for heavy commercial use or require specific lift profiles for bagging/mulching.
