Mower Chute Blocker Fit for Ferris, Exmark, Gravely, Hustler and Toro Mowers, Kubota, Grass Flap Chute Blocker OE ACS6000ULS, 088-6003-00 for Most ZT Mowers

What It Is

This mower chute blocker redirects grass clippings downward for mulching or side-discharge control, designed for zero-turn mowers from Ferris, Exmark, Gravely, Hustler, Toro, and Kubota. It replaces OEM part ACS6000ULS (088-6003-00) and is used on 48” to 72” decks.

Fitment & Compatibility

Before buying, confirm your deck size (48–72 inches) and check that your mower’s discharge chute mounting holes match the blocker’s bolt pattern—measure center-to-center spacing if possible. This part is aftermarket, not Toro OEM, so verify it fits your specific model: it works with most ZT mowers from the listed brands but may require minor drilling on older or non-standard decks. For Kubota, check if your deck uses a curved or straight chute mount. Always cross-reference your OEM part number (e.g., ACS6000ULS or 088-6003-00) to ensure compatibility.

Key Things to Know

• Quality: Some users report thinner plastic than OEM, which may crack under heavy use or in cold weather. Inspect for warping before installation.
• Installation: Moderate difficulty—you’ll need a drill and 3/8” bolts if predrilled holes don’t align. Expect 15–30 minutes; secure with provided hardware.
• Common Gotcha: The blocker may not seal tightly against the deck, causing clippings to leak—use a rubber gasket or weatherstrip to improve fit.
• Performance: Works well for mulching but can reduce side-discharge efficiency on wet grass; adjust mowing speed to avoid clogs.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn OEM chute blocker and have a compatible ZT mower (48–72” deck). Skip it if you want exact OEM fitment or mow in heavy, wet conditions—spend more on the genuine Toro part for better durability and seal.
