Hey Guys, I went to my local Deere Dealer to get Hydraulic Fluid in order to service my hydraulic fluid system. They advised me to use regular Engine Oil PLUS 50 in the system rather than the TORQ GUARD SUPREME fluid that I had in mind using. When New , the system had what appeared to be a greenish colored fluid in the system. I have looked in my Operator's Manual & it appears that both are ok to use, but, I have in the past & am having again issues with the Temp sensor acting up. I replaced the original one less than 200 hours ago & it appears that it's time to do that again, I just want to make sure that I use what's best for fluid in the system.. Thank you all for your thoughts.
