John Deere currently identifies GY21099 as compatible with the 190C, D170, E180, G110, LA150, LA175 and S180. Always verify your original spindle part number before ordering.
This listing includes 3 spindle assemblies and is intended for customers replacing the spindle assemblies across the compatible 54" deck. If you only need to replace one damaged spindle, Green Dade also sells the 80-11-766 spindle individually.
Do not order by mower brand or 54" deck size alone. Confirm that your mower uses the GY21099, GY20867 or GY20592 spindle family. John Deere mower decks with the same cutting width may use different spindle designs depending on model and production configuration.
