MowerPartsGroup (3) Hi-Lift Blades 48" Cut Fit Hustler Fas Trak Sport X-one 795757 Scag 482877

What It Is

These are three high-lift lawn mower blades designed for 48-inch cutting decks, intended to improve grass clipping discharge and bagging performance on commercial zero-turn mowers.

Fitment & Compatibility

Before buying, verify your deck measures exactly 48 inches from blade tip to blade tip. These blades fit Hustler Fas Trak, Sport, and X-One models (OEM #795757) and Scag models (OEM #482877). Measure your existing blade length (should be roughly 18.5 inches), width (2.5–3 inches), and center hole diameter (typically 1 inch). Check that your spindle bolt pattern matches—these use a standard 5-point star or hex center hole. Not compatible with 36-inch, 52-inch, or 60-inch decks. Confirm your deck brand and model number on the mower’s serial tag.

Key Things to Know

• Quality: Hi-lift blades create more suction than standard blades, improving bagging and side discharge but may increase engine load and reduce fuel efficiency slightly.
• Installation: Straightforward—use a torque wrench to tighten spindle bolts to 70–90 ft-lbs. Wear gloves; sharp edges can cut.
• Common Gotcha: Ensure blades are oriented correctly (lift edge up). Reversing them reduces cutting performance and can damage the deck.
• Durability: Heat-treated steel holds an edge well but may dull faster on sandy or rocky terrain. Sharpen after 10–15 hours of heavy use.

Should You Buy It

Buy these if you own a 48-inch Hustler or Scag zero-turn and need replacement blades that match OEM specs at a lower price, especially for bagging or thick grass. Avoid if your deck is a different size or you prefer standard-lift blades for minimal engine strain.
