GX22425 GX22426 Deck Wash Water Port Plate Kit Compatible with John-Deere X400, X500, X700, Z375, Z525E, Z515E, Z465, Z435, Z445, Z425

What It Is

This deck wash water port plate kit lets you attach a garden hose directly to your mower deck for quick, tool-free cleaning. Designed for select John Deere X500, X700, Z300, Z400, and Z500 series mowers, it replaces the factory plug or missing port to flush grass clippings from under the deck.

Fitment & Compatibility

Before buying, verify your mower model and deck size. This kit fits John Deere X300, X500, X700 series (all deck sizes), and Z375, Z525E, Z515E, Z465, Z435, Z445, Z425 models. It does not fit X300R, X304, X320, or older X700 series decks without the factory port hole. Measure the existing port hole diameter—it must be 1.5 inches (38mm). The kit includes the port plate, gasket, and mounting screws. It’s an aftermarket replacement for OEM part GX22425/GX22426, so it should match the factory hole pattern, but check that your deck has the pre-drilled mounting holes (most 2008+ models do).

Key Things to Know

• Installation: Requires removing one existing plug (if present) and screwing the plate into place. No drilling or special tools needed. Takes about 5 minutes.
• Quality: The plastic plate is durable but can crack if overtightened. Hand-tighten screws; use a wrench only for final snugging.
• Gasket: Includes a foam gasket—ensure it’s seated evenly to prevent leaks. If the gasket gets hard over time, replace it.
• Gotcha: If your deck has never had a wash port, you may need to drill a 1.5-inch hole. Check your deck’s underside for a dimple or marking indicating the location. Not all decks have this—verify before buying.

Should You Buy It

If you own a compatible John Deere mower and want an easy, low-cost way to clean under the deck after each use, this kit works well. It’s a direct fit for most 2008+ X-series and Z-series models with the pre-drilled port. Skip it if your deck lacks the mounting holes or if you prefer a universal wash port that requires drilling. At $11.99, it’s a solid value for keeping your deck rust-free and cutting efficiently.
