Mulch Cover Kit Compatible with 54-Inch Lawn Tractor Deck for Husqvarna/Craftsman(Model 917) Lawn Tractor Deck with Mounting Hardware- Replaces 960120040 532187298

What It Is

This mulch cover kit converts a 54-inch lawn tractor deck from side-discharge or bagging mode to mulching, allowing grass clippings to be finely cut and returned to the lawn as natural fertilizer. It’s designed for Husqvarna and Craftsman (Model 917) lawn tractors with a 54-inch deck.

Fitment & Compatibility

Before buying, verify your deck is exactly 54 inches wide—measure from blade tip to blade tip. This kit replaces OEM part numbers 960120040 and 532187298, so it fits specific Husqvarna and Craftsman Model 917 series tractors. Check your tractor’s model number (often under the seat or on the frame) and confirm your deck’s spindle and blade bolt pattern matches. Some aftermarket decks or older Craftsman models may require additional hardware not included. The kit comes with mounting hardware, but ensure your deck has the necessary mounting holes—measure the distance between existing discharge chute holes.

Key Things to Know

• Quality concerns: At a 3.7-star average, some users report thin plastic that cracks under heavy use or in hot sun. Consider reinforcing with metal brackets if you mow tough, tall grass.
• Installation difficulty: Moderate. You’ll need to remove the side-discharge chute, align the cover over the deck opening, and bolt it on. Allow 20-40 minutes; a socket set and possibly a wrench are required.
• Common gotcha: The cover may not seal tightly against all deck contours, causing clippings to escape. Check for gaps after installation and trim rubber seals if needed.
• Blade change: You should switch to mulching blades (not included) for proper cutting. Standard blades won’t create a fine enough clip.

Should You Buy It

This kit is a budget-friendly option if you already own a compatible 54-inch Husqvarna or Craftsman Model 917 tractor and want to mulch without buying a whole new deck. It’s best for light-to-moderate mowing on even lawns—if you frequently cut thick, wet grass, invest in a sturdier metal kit or OEM part for durability.
