Sorry about the pervious post as I wasn't done before it was posted. My mistake.
A while back I was watching a program on the RFD channel on T.V. John Deere was discussing the different types of oil, fluids, grease, etc. that they make and what they are used for. I was amased at the testing, analysis and technology that went into making the different types. I have a X595 and regularly change most fluids, filters using only JD brands. One fluid that I would just check just to make sure it was full was the fluid for the front axle as I didn't use FWD that much. After watching this program, I went out and changed every fluid on my X595. I always wondered why anyone would consider using a different brand than what JD recommended for their JD equipment. I know that everyone that does switch to something different always checks the specs but I have to believe there is a difference in the compounds they use to make the different brands. I know what I have invested in my X595, and I would NEVER consider using something other that what JD has developed and tested and recommends for my X595. This could also become a warranty issue if something happened to your machine/eqiupment if you were using a different brand. I know you could argue it met the same specs but that is my point, you would have to argue it but if you used the JD brand, there wouldn't be a question. Please don't get me wrong, I'm not knocking other brands as I do use them for other applications. Since I own and believe in JD products, that is what I use. If I owned a Kubota, I would use what they made and recommended and the same for other manufacturers. Just my 2 cents.
Curt.
