Caltric Deck Wash Water Port Plate Compatible with John Deere L130 CV23S 31P677 LA100 LA105 LA110

What It Is

The Caltric Deck Wash Water Port Plate is an aftermarket replacement for the factory-installed water port assembly on select John Deere lawn tractors. It allows you to connect a garden hose directly to the mower deck for cleaning grass clippings without removing the blade or tipping the mower.

Fitment & Compatibility

Before buying, confirm your mower deck already has a factory water port hole (typically a 1-inch diameter opening on the deck top). This plate is designed to replace the original John Deere part on models with 42-inch or 48-inch stamped steel decks, including the L130, LA100, LA105, LA110, and the CV23S 31P677 engine platform. It is not universal—it will not fit decks without a pre-drilled port or decks with a different port geometry. Compare the plate’s mounting hole spacing (approximately 2.5 inches center-to-center) and gasket shape to your existing port. If your original port is damaged or missing, measure the opening before ordering.

Key Things to Know

• Quality concerns: With a 1.0/5 rating from a single review, this part may have fitment or durability issues. Check for thin plastic or misaligned screw holes in the product images.
• Installation difficulty: Easy—remove the old port screws, clean the deck surface, apply the included gasket, and screw on the new plate. No special tools required.
• Common gotcha: The plastic port can crack if over-tightened or if the deck is used on rough terrain. Use hand-tightening only, and avoid using a power washer directly on the port.
• Seal issues: The included gasket may not match the deck curvature on all models. If it leaks, apply a thin bead of silicone sealant between the gasket and deck.

Should You Buy It

This part is only worth considering if you’re on a tight budget and your original John Deere water port is broken, but be prepared for potential fitment or sealing headaches. For just a few dollars more, an OEM John Deere port (part number M154286) is likely more reliable and will save you the hassle of returns or leaks.
