3PK USA Mower Mulching Blades for Scag 61" 481708 481712 482787 482879 Ferris 5101755

What It Is

This is a set of three mulching blades designed for 61-inch mower decks, compatible with select Scag and Ferris zero-turn mowers. Mulching blades cut grass into fine clippings that decompose quickly, eliminating the need to bag.

Fitment & Compatibility

Before buying, confirm your deck is exactly 61 inches. These blades fit Scag models using OEM part numbers 481708, 481712, 482787, or 482879, and Ferris models using OEM part number 5101755. Measure your current blade’s length, width, and center hole diameter—these are aftermarket replacements, so slight dimensional differences may affect fit on non-listed models. Always verify your mower’s model and serial number against the seller’s fitment chart.

Key Things to Know

• Quality: Made in the USA, generally well-reviewed for durability and balance. Check for consistent sharpness out of the box—some users report needing to sharpen before first use.
• Installation: Replacement is straightforward with basic tools (socket wrench and torque wrench). Always disconnect the spark plug and lift the deck safely. Torque blade bolts to manufacturer specs (typically 70–90 ft-lbs).
• Common Gotcha: Mulching blades require sharp edges to work effectively. Dull blades tear grass, causing brown tips. Sharpen at least once per season or after heavy use.
• Performance: Expect finer clippings than standard blades, but avoid cutting more than 1/3 of grass height at a time to prevent clumping.

Should You Buy It

If you own a 61-inch Scag or Ferris mower and want to switch from bagging or side-discharge to mulching, this is a solid, cost-effective choice. It’s best for operators who maintain sharp blades and cut regularly—not ideal for overgrown or wet grass.
