I'm helping out at small horse farm and the tractor they use is an old Kabota, not sure at the model my guess is an '83ish B5200E 14 HP Deisel, gear drive. Anyway the hydrolines to the front bucket are shot and apparently you need a screwdriver to start the machine. Whats involved in replacing the hydraulic lines? Do you think the starter is bad or just a solinoid? I know these are tough to answer but any help would be appreciated.
