After the post on oil changes and the great conversation it started I have another question concerning to owners manual, Dealership, and some talk I've seen/heard. The Hydro filter on the 1023e/1025r/1026r's. I've owned several Hydro driven tractors and most of them recommend Hydro fluid changes around 200-400 hours and an annual filter change and top off from the fluid loss whether it was time for the Hydro fluid change or not . I seen a post lately ( on GTT??? Can't remember for sure) that Deere is now recommending changing the Hydro filter ANNUALLY whether you do a fluid change or not now? I owned some Cubs that recommended the same thing so was wondering if this is feasible? And if so, isn't the filter BELOW the Hydro fluid level which would cause a lot of fluid loss during the filter change? Thoughts??
