GY00115 Deck Mulch with Mounting Accessories Compatible with John-Deere 42" Mower Decks Cover 102 105 110 118 115 125 135 D/E/L/X/LA Series Mowers

What It Is

This is a mulch cover kit (GY00115) designed to block the discharge chute on John Deere 42-inch mower decks, converting them from side-discharge to mulching mode. It includes the cover, mounting hardware, and gasket for a clean install.

Fitment & Compatibility

• Deck size must be exactly 42 inches – measure your deck’s cutting width, not the tractor model number.
• Compatible with John Deere 100, 200, D, E, L, X, and LA series mowers with 42” Edge, 7-Iron, or standard stamped decks (models: 102, 105, 110, 118, 115, 125, 135, D/E/L/X/LA variants).
• Not for 48” or 54” decks – even if the tractor model matches.
• Check your deck’s mounting holes: this uses two bolts and a latch. Verify your deck has the pre-drilled holes (most 42” Edge/7-Iron decks do).
• OEM part replacement: Direct fit for John Deere GY00115 (original part). No modifications needed.

Key Things to Know

• Quality: Plastic cover is durable but can warp under high heat if left on during extended heavy mowing. Check gasket seal annually.
• Installation: Easy – remove the discharge chute, attach cover with provided bolts, latch into place. Takes 10 minutes.
• Gotcha: The latch mechanism may feel loose on some decks – tighten bolts fully and ensure the gasket sits flush to avoid grass blowout.
• Mulching performance: Works best with a high-lift mulching blade (sold separately). Standard blades may leave clumps in wet grass.

Should You Buy It

Buy this if you have a 42” John Deere deck, want to mulch leaves/grass without side discharge, and prefer an OEM-style fit over universal kits. Skip it if you need a heavy-duty steel cover or have a deck size other than 42 inches.
