I have just purchased a 1967 Case 830 Comfort King and I of course have some questions. I purchased it from an old farmer who recently passed away and has had this tractor from new. I am a JD man but this tractor looked good and thought it might make a good back up tractor and do some field work and possibly Round baling. The serial # is 8318928 . Now I am trying to check the Hydraulic Fluid and of course need to know how to fill the Hydraulic fluid if needed and would like to know the location of the hydraulic pump. I would like to put more lighting on the tractor and I am wondering since it is a 6 volt system with two 6 volt batteries if I can use 12 volt lights or if I have to buy special lights. I am also looking for a service or operators manual. Does anyone have one they could copy and send digitally or would be willing to sell? Thanks for any help. I am sure I will have more questions as I learn more about the tractor.
