What It Is

This 604579 Deck Lift Link Replacement Kit is a multi-piece repair set designed for Hustler Raptor SD zero turn mowers. It replaces worn or broken lift linkage components that control deck height adjustment, restoring proper cutting height range and deck leveling.

Fitment & Compatibility

Direct fit for: Hustler Raptor SD models using OEM part numbers 936682, 937821, 936484, and 934547. Kit includes 604579, 118018, 791673, 605114, 767954, and 086660 components.

Before buying:

• Verify your mower’s deck size (42”, 48”, 54”, or 60”) – the kit works across all Raptor SD decks but check your specific model year (2015-2022 typically compatible).
• Measure your existing lift link length and pin hole spacing – this kit replaces the main lift link and associated hardware, not the entire lift system.
• Confirm your current part is actually a 604579 or one of the listed OEM numbers – look for stamped numbers on the existing link.
• This is an aftermarket replacement, not OEM Hustler. Expect identical dimensions but potentially different finish quality.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck (2-3 hours for first-timers). Basic hand tools (wrenches, sockets, punch) and a jack or blocks to support the deck are needed.
• Common gotcha: The bushing (086660) often seizes to the pin – plan to replace all hardware in the kit, not just the link. Soak rusted fasteners with penetrating oil 24 hours before starting.
• Quality note: At $9.69, this is a budget fix. The metal may be softer than OEM, so check for burrs or sharp edges and file if needed. Expect 1-2 seasons of normal residential use.
• Alignment critical: After installation, measure deck height at all four corners – an incorrectly installed link will cause uneven cutting. Adjust the lift stop bolts if the height range is off.

Should You Buy It

If your Hustler Raptor SD’s deck won’t lift properly or the lift link is bent/worn, this kit is a cost-effective repair for DIY owners comfortable with deck removal. It’s not for commercial operators needing OEM durability, but for residential use at this price, it’s a solid value.
