USA Premium Store Scag Zero Turn Mower Deck Blades - 48'' - Fits Freedom Z & Liberty Z

What It Is

This is a set of three replacement blades for 48-inch Scag zero-turn mowers—specifically the Freedom Z and Liberty Z models. Designed for residential and light commercial use, these blades lift and cut grass, then discharge it out the side or into a bagger.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck (measure deck width, not cutting width). These blades fit Scag Freedom Z (S/N 8000000 and up) and Liberty Z (S/N 6000000 and up) models with 48-inch decks. They are aftermarket replacements for OEM part 48417. Check your current blade length: these measure 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.25-inch thick. Verify bolt pattern—these use a single center hole, no offset. If your deck uses a different blade shape (e.g., mulching or gator style), these are standard lift blades for side-discharge cutting.

Key Things to Know

• Quality: Made from heat-treated steel; rated 4.6 stars from 17 reviews. Users note they’re slightly thinner than OEM, but hold an edge well for the price.
• Installation: Straightforward—remove the center bolt (likely 5/8-inch or 15/16-inch), swap blades, torque to 70-90 ft-lbs. Use a blade locking tool or wood block to prevent spinning.
• Common gotcha: These blades are not for mulching or bagging. If you use a mulch kit or bagger, you may need OEM or gator-style blades for better performance.
• Balance: Check balance before installing—unbalanced blades cause vibration and deck damage. A simple nail-in-wall test works.

Should You Buy It

If you own a 48-inch Scag Freedom Z or Liberty Z and need a budget-friendly replacement for standard side-discharge mowing, this set delivers good value. Skip it if you require OEM-exact thickness, mulching capability, or if your deck has a different blade hole pattern. For residential lawns and light commercial, it’s a solid pick.
