Mulch Cover Kit Compatible with 46-Inch Lawn Tractor Deck – Fits Husqvarna/Craftsman Model 917 – Includes Mounting Hardware – Replacement for Part 532406581

What It Is

A mulch cover kit that replaces the side-discharge chute on a 46-inch lawn tractor deck, allowing grass clippings to be recirculated and finely chopped for nutrient-rich mulching. Designed for Husqvarna and Craftsman Model 917 series tractors.

Fitment & Compatibility

• Deck size: Must be exactly 46 inches (measure from blade tip to blade tip).
• Model check: Fits Husqvarna tractors with 46″ fabricated or stamped decks and Craftsman Model 917 (e.g., 917.289260, 917.289270).
• OEM part: Replaces Husqvarna/Craftsman part 532406581. Aftermarket, not OEM.
• Hardware included: Bolts, nuts, and washers for mounting. Verify your deck has the two existing holes for the chute attachment.
• Not compatible with: 42″ or 54″ decks, or tractors with a different chute mount pattern.

Key Things to Know

• Quality: Users report solid plastic construction, but some note the latch tabs can be brittle if overtightened. Hand-tighten only.
• Installation: Easy – remove side-discharge chute, align cover, and bolt on. No blade removal needed. Takes about 10 minutes.
• Common gotcha: If your deck has a “quick-attach” chute system, this kit may not fit. Check for two separate bolt holes, not a single latch.
• Performance: Requires sharp blades and dry grass for best mulching. Wet grass clumps and may clog the cover.

Should You Buy It

Right for you if you own a 46-inch Husqvarna or Craftsman 917 tractor, want to mulch without buying a new deck, and don’t mind basic DIY. Skip it if you need OEM fitment, have a different deck size, or frequently mow wet grass.
