John Deere OEM Shield GY21773 — Fits 107S, D100–D130, LA & X Series

Upgrade your mower with the John Deere OEM shield, part number GY21773. This genuine shield is designed to align with Deere’s original specifications and replaces GX22644. It’s built to integrate smoothly with a broad range of tractors, helping protect the deck area and nearby components from impact and debris during everyday mowing tasks. While it doesn’t guarantee results on every machine, the OEM design provides a factory-fit option for those seeking a direct replacement that mirrors the original equipment’s intent and performance.

For many owners, a shield that slots into place without modification means quicker service and less downtime. The GY21773 shield is intended to align with the mounting points used across several Deere families, including the 107S, multiple D-series models, the E-series, LA-series, and the X-series. Always refer to the original Owner’s Manual to confirm model-by-model compatibility and to ensure you’re using the correct mounting hardware and deck interface. This shield is engineered to work with the specified deck configurations, so a proper fit supports efficient maintenance and a tidy engine compartment presentation.

The shield’s design reflects Deere’s attention to detail: it’s shaped to follow the contour of the mower deck and to deflect stones, grass, and other debris away from critical components. When you replace a worn or damaged shield, you may notice a cleaner workflow during routine maintenance and a more streamlined appearance of the deck area. Keep in mind that performance depends on correct installation and routine inspection for wear or cracking over time.
