High Lift Blade Set for Scag Ferris 61 inch Deck 48111 482879 1520842 Husqvarna 539101733

What It Is

This is a set of three high-lift blades designed for 61-inch commercial zero-turn mower decks. High-lift blades increase airflow under the deck, improving grass discharge into the bag or side chute—ideal for tall, wet, or thick grass where standard blades leave clumps.

Fitment & Compatibility

• Deck size: Fits only 61-inch cutting decks. Measure your deck width to confirm.
• Direct fit models: Scag (48111, 482879, 1520842) and Ferris (part 1520842) 61-inch decks. Also fits Husqvarna (539101733) on certain 61-inch commercial zero-turns.
• OEM vs aftermarket: These are OEM Husqvarna blades, not generic aftermarket. That means exact hole pattern, thickness, and lift profile.
• Measure before buying: Check blade length (typically ~20.5 inches end to end), center hole diameter (usually 1 inch), and offset/centering pin location. If your deck uses a different spindle or blade adapter, these won’t fit.
• Not universal: Will not fit 48-inch, 52-inch, or 72-inch decks. Also not compatible with most residential riding mowers (e.g., Craftsman, John Deere 100-series).

Key Things to Know

• Installation difficulty: Moderate. Requires a socket wrench and torque wrench (recommended 70–90 ft-lbs). Use thread locker on spindle bolts if not already applied.
• Common gotcha: High-lift blades create more suction, which can strain the engine and belt if your deck is not designed for them. On some Ferris/Scag decks, they may reduce ground speed in very thick grass to avoid bogging.
• Quality & durability: Heat-treated steel with a hardened edge. Expect 20–30 hours of mowing before noticeable dulling—sharpen or replace at that point.
• Balance check: Always spin-test each blade on a balancer after installation. A single unbalanced blade will cause vibration and spindle wear.

Should You Buy It

If you own a 61-inch Scag, Ferris, or Husqvarna commercial zero-turn and regularly bag or side-discharge in heavy grass, this set is a solid upgrade over standard blades. It’s not for mulching, and it will increase deck wear slightly—but for bagging performance, it’s a reliable OEM choice at a fair price.
