Caltric Deck Wash Water Port Plate Compatible with John Deere X320 X324 X330 X340 X350 X350R X354

What It Is

This is a replacement water port plate for the deck wash system on select John Deere lawn tractors. It mounts to the top of the mower deck and connects a garden hose to flush grass clippings and debris.

Fitment & Compatibility

This Caltric plate is designed for John Deere X300-series tractors with 42-inch, 48-inch, and 54-inch decks. It fits models X320, X324, X330, X340, X350, X350R, and X354. Before buying, confirm your deck’s OEM part number (usually stamped near the port) — it replaces John Deere part #GX20073. Measure the port opening diameter (approximately 1.5 inches) and verify the mounting hole pattern matches your deck. This is an aftermarket part, not OEM, so it may differ slightly in plastic texture or color.

Key Things to Know

• Quality: Caltric is a reputable aftermarket brand; users report good fit and seal. Plastic is slightly less rigid than OEM but functional.
• Installation: Easy — remove the old plate (often held by two screws), clean the deck surface, and install the new one with the included gasket. Takes about 10 minutes.
• Common gotchas: The gasket must be seated perfectly to avoid leaks. Over-tightening screws can crack the plastic. If your original port is rusted or stripped, you may need to drill out old screws.
• Performance: Works as intended for hose flushing. No difference in water flow compared to OEM.

Should You Buy It

If you need a reliable, low-cost replacement for a broken or missing deck wash port on a compatible John Deere X300-series mower, this is a solid choice. It’s not for high-use commercial decks, but for residential owners, it’s a practical fix at half the OEM price.
