42" Deck Mulch Cover For S100 S110 S120 S130 S240 X105 X106 X110, Replacement for John Deere OEM

What It Is

This 42-inch deck mulch cover replaces the standard discharge chute or bagger attachment on select John Deere lawn tractors, converting the mower to a mulching setup that re-cuts clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, verify your mower deck is exactly 42 inches (measured blade tip to blade tip). This cover fits John Deere S100, S110, S120, S130, S240, X105, X106, and X110 models with 42-inch decks. It replaces John Deere OEM part number M156665 or similar. Aftermarket fit may vary—check that your deck’s mounting holes align (typically two bolts on top of the deck near the discharge opening). Measure your existing chute mounting points to confirm spacing matches this cover’s brackets.

Key Things to Know

• Installation difficulty: Easy—remove two bolts, slide off the old chute or bagger adapter, and bolt on the mulch cover. No tools beyond a socket wrench.
• Quality concerns: At this price and 3.0-star rating, expect thinner plastic than OEM. Some users report warping or cracking after a few seasons of use.
• Performance note: Mulching requires sharp blades and dry grass. This cover alone won’t improve cut quality if your blades are dull or you’re mowing wet grass.
• Common gotcha: The cover may not seal tightly against the deck, allowing clippings to escape. Check gasket fit after installation and consider adding foam weatherstripping for a better seal.

Should You Buy It

Buy this if you want a budget-friendly way to convert your compatible John Deere to mulching without spending on OEM parts. Skip it if you need long-term durability, mow in tough conditions (wet grass, thick turf), or prefer a guaranteed OEM fit. For occasional mulching on a smaller lawn, it’s a functional, low-cost option.
