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

What It Is

The ACS6000ULS is an aftermarket chute blocker designed to convert an open-discharge zero-turn mower deck into a mulching or side-discharge system. It replaces the Advanced Chute System 088-6003-00 and includes a discharge shield to contain clippings.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch or 72-inch deck with a standard chute opening. This blocker fits most zero-turn brands (Ferris, Exmark, Gravely, Hustler, Toro) but only models that accept the Advanced Chute System—check your deck’s mounting holes and bracket design. Measure the chute opening width: it must match the blocker’s flange. OEM part 088-6003-00 is the direct reference; if your mower uses that, this fits. For non-standard decks (e.g., Scag, John Deere), measure carefully or verify with your dealer.

Key Things to Know

• Build quality: Mixed reviews; some users report plastic feels thinner than OEM. Inspect for warping or loose fasteners before first use.
• Installation: Moderate difficulty—requires removing existing chute and aligning brackets. Tools needed: 10mm socket, screwdriver, and possibly a drill if your deck lacks pre-drilled holes.
• Common gotchas: The included discharge shield may not seal tightly on all decks, causing clippings to escape. Check gasket alignment after install.
• Warranty: Aftermarket part; no manufacturer warranty from Toro. Returns depend on seller.

Should You Buy It

Buy this if you need a budget-friendly chute blocker for a compatible zero-turn mower and are comfortable with minor adjustments. Skip it if you want OEM fit-and-forget quality or have a non-standard deck—spend more on the genuine Toro 088-6003-00 for guaranteed sealing and durability.
