I have a ford 1600 tractor that the 3 pt lift will not go up or down. it seems to be stuck. i have been reading on the forum and it seems that the hydraulic fluid and transmission fluid are combined & with operation will equal out. My tractor was very low on fluid, i added new Holland 134 equivalent from TSC (2.5 gallons) no change. i am now looking for the hydraulic filter to possibly clean. I would also like a parts diagram if any one has it on the hydraulic system. If anyone has any more suggestions, i welcome your comments and suggestions.
