DVPARTS Mulching Cover GY20417 Compatible with 48" John Deere L120 L130 LA130 LA140 LA145 155C 100 Series D140 D150 D155 D160 E140 E150 E160 E170 Lawn Tractors

What It Is

The DVPARTS Mulching Cover GY20417 replaces the discharge chute on 48-inch John Deere lawn tractors, blocking grass clippings from exiting the deck so the blades recut them into fine mulch. Designed for models like the L120, L130, LA130, LA140, LA145, 155C, D140, D150, D155, D160, E140, E150, E160, and E170, it’s a direct fit for converting side-discharge decks to mulching mode.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch stamped steel deck (not a 42-inch or fabricated deck). Check your model number against the list: John Deere 100 Series (e.g., LA130, LA140, LA145), L Series (L120, L130), D Series (D140–D160), and E Series (E140–E170). This is an aftermarket part, not OEM, but it matches the John Deere GY20417 part number. Measure the deck’s discharge opening—it should be roughly 12 x 6 inches—and ensure the two mounting holes align with the chute bracket on your mower. If your deck has a factory mulching plug, this will replace it; if not, you’ll also need a mulching blade kit (sold separately) for proper cutting.

Key Things to Know

• Quality & durability: Made from heavy-duty plastic, similar to OEM. It may be slightly thinner, but holds up to regular use without cracking under normal mulching conditions.
• Installation difficulty: Simple—takes 5–10 minutes. Remove the discharge chute (usually two bolts or wing nuts), align the cover, and secure with the same hardware. No tools needed if using existing wing nuts.
• Common gotcha: This cover only works for mulching; you must remove it when bagging or side-discharging. Also, if your deck is badly rusted or the mounting tabs are bent, the cover may not seal tightly, reducing mulching efficiency.
• Compatibility check: Double-check your deck’s year—some early 100 Series models (pre-2005) may have a different bracket pattern. Measure before ordering.

Should You Buy It

If you own a compatible 48-inch John Deere tractor and want a budget-friendly way to convert to mulching, this is a solid choice. It’s cheap, easy to install, and works as intended—just pair it with mulching blades for best results. Avoid if you need a heavy-duty cover for commercial use or if your deck shows significant wear.
