2-Pack Hustler 604579 Deck Lift Links for Raptor SD Zero Turn Mower | Sturdy replacement links improve cutting efficiency and upgrade your zero-turn mower easily.

What It Is

This 2-pack of Hustler 604579 deck lift links replaces the factory linkages that connect your Raptor SD zero-turn mower’s deck lift arm to the deck itself. They’re used to raise and lower the cutting deck, and worn or bent links cause uneven cutting and inconsistent height adjustment.

Fitment & Compatibility

• Direct OEM replacement for Hustler part number 604579 – not aftermarket universal.
• Fits Hustler Raptor SD models (52-inch and 60-inch deck sizes) – double-check your model number on the mower’s data tag.
• Does NOT fit Raptor (non-SD), Raptor SX, Super S, or commercial Hustler zero-turns.
• Measure your original link: overall length (center of hole to center of hole) should be approximately 6.5 inches. If yours matches, these are correct.
• Check hole diameter – these use 3/8-inch hardware. If your mower uses a different bolt size, they won’t work.

Key Things to Know

• Inspect before buying: If your existing links are just bent, not broken, these are a direct swap. If the deck lift arm or mounting brackets are damaged, replacing links alone won’t fix the issue.
• Installation is easy – remove two bolts per link, swap, and retighten. No special tools required. Expect 10–15 minutes total.
• Common gotcha: The left and right links are identical – no “driver” or “passenger” side. Just align the holes and bolt them in.
• These are stamped steel, not cast. They’re strong enough for residential use but can bend if you hit a large obstacle at full speed. They’re a wear item.

Should You Buy It

If your Raptor SD’s deck is sagging, uneven, or you’ve bent a link hitting a tree root or rock, this is the correct, cheap fix. It’s ideal for DIY homeowners who want to restore proper cutting height without replacing the entire deck assembly. Skip if your mower is a different Hustler model or if the lift arm itself is damaged.
