GY21084C GY21773 GY21084 GX22456 LH/RH Shield w/Screws Compatible with John D-eere 107S, D100, D105, D110, D120, D125, D130 Series Tractors

What It Is

This is a replacement left-hand (LH) and right-hand (RH) mower deck shield set, complete with mounting screws, designed to redirect grass clippings and debris away from the tractor’s rear tires. It fits specific John Deere 100-series lawn tractors—models like the D100, D105, D110, D120, D125, D130, and the 107S.

Fitment & Compatibility

Before buying, confirm your mower deck size (42”, 48”, or 54”) and model year. This shield set is compatible with John Deere 100-series tractors and replaces OEM part numbers GY21084C, GY21773, GY21084, and GX22456. It is an aftermarket part, not genuine John Deere, so verify that your deck’s mounting holes align with the included screws. Measure the original shield’s length and mounting bracket spacing—these shields are typically about 12–14 inches long. Not for use on older 200-series or X-series tractors.

Key Things to Know

• Material & Quality: Made of durable, UV-resistant plastic; slightly thinner than OEM but holds up well under normal use. Screws are included but may be shorter than originals—check thread length before installing.
• Installation Difficulty: Easy, 10–15 minute job. You’ll need a socket wrench or screwdriver to remove the old shields and reattach the new ones. No drilling or modifications required if your deck has the factory mounting holes.
• Common Gotchas: The left and right shields are mirror images—don’t mix them up. Some users report that the included screws strip easily; using a drop of threadlocker or replacing with stainless steel screws can help. Ensure the deck is clean and free of grass buildup for a snug fit.
• Performance: Effectively reduces grass spray on rear tires during side-discharge mowing. May not fit perfectly on decks with aftermarket mulching kits installed.

Should You Buy It

If your original John Deere shields are cracked, missing, or worn out, this aftermarket set is a solid, cost-effective replacement. It’s a direct fit for the listed 100-series models, easy to install, and priced well below OEM. Best for DIY owners who want to restore proper debris deflection without spending dealer-level money. Skip it if you need exact OEM fitment or have a non-standard deck setup.
