In a 2009 JOHN DEERe 6115D tractor, you should check the hydraulic fluid when the hydraulic system is warm, as this allows for more accurate readings. The fluid expands when heated, providing a better indication of the fluid level during normal operating conditions. It's best to run the tractor for a short period before checking the level to ensure the fluid is circulating. Always consult the owner's manual for specific guidelines related to your tractor model.
