SW MINNESOTA | How often do most guys change hydraulic oil in tractors? Book says 1500 hours my two main tractors that get 500-750 hours per year have been getting changed every two years. Have a couple that only get 250-400 per year and have been doing them every two years also. Filters are always changed yearly on everything. Is this overkill? Dad and grandpa also preached starting year with fresh fluids and I like that theory too just wonder how necessary it is. | |
