Mower Chute Blocker Discharge Shield Compatible with Ferris Exmark Gravely Hustler, Advanced Chute System Replaces ACS6000ULS 088-6003-00 Most Zero Turn ZT Mowers

What It Is

This is a universal mower chute blocker designed to redirect grass clippings downward for mulching or side-discharge control. It fits most zero-turn mowers with a standard advanced chute system, replacing OEM part ACS6000ULS (088-6003-00) for Ferris, Exmark, Gravely, and Hustler models.

Fitment & Compatibility

• Deck size: Works with 48–72 inch decks, but verify your chute mounting hole spacing (center-to-center) matches the shield’s bracket. Typical spacing is 3.5–4 inches.
• Brand/model: Compatible with Ferris (IS, FW, IC series), Exmark (Lazer Z, Quest, Turf Tracer), Gravely (ZT series, Pro-Turn), Hustler (FasTrak, Super Z, Z). Not guaranteed for older or non-standard chute systems.
• OEM vs aftermarket: This is an aftermarket replacement for ACS6000ULS. If your mower uses a different OEM chute blocker (e.g., Exmark 1-423-2), measure the bracket width and pin size before buying.
• What to check: Measure your existing chute blocker’s mounting holes (distance between the two bolt holes) and the diameter of the pivot pin. Also confirm your deck has a pre-drilled bracket—some zero-turns lack this.

Key Things to Know

• Quality: Mixed reviews—some report flimsy plastic that cracks under heavy use or UV exposure. The rubber flap is flexible but may not seal tightly on all decks.
• Installation: Easy (10-20 minutes) with basic tools: remove old chute, align new shield, insert pin, and tighten. No drilling required if your deck is pre-drilled.
• Common gotchas: The shield may not stay fully closed during operation, causing clippings to escape. Some users add a bungee cord or zip tie for a tighter seal. Check that the discharge opening is fully covered—if not, clippings may spray sideways.
• Warranty: No manufacturer warranty mentioned; buy from a seller with a return policy.

Should You Buy It

This is a budget-friendly option if you already have a compatible deck and need a quick mulching shield without paying OEM prices ($130+). But if you want a durable, perfect-fit solution for heavy commercial use, skip it—the mixed reviews suggest you’ll likely need to modify it or replace it sooner than expected.
