I have a JD 3020 according to the chassis number it is a 656800 so I assume a 1965 model, Row Crop, Diesel, Syncro Range Trans.
Here is my problem while using the brake pedal locked up not sure if it was in the up position or down brakes did work prior. I did try to bleed and got signs of water in hydro oil. So I changed the oil and the filter, 1 large drain plug close to the back and a small plug that was more up front. Put in new filter and oil although I did not use the JD brand special oil the owners manual suggested but a compatible from a local farm store. When this and a couple of other maintenance projects were complete I started the tractor and ( the hydraulics were always a little slow starting, take a few minutes for the steering, 3 point lift, and loader to activate but they did start working. So far so good. I let run for a few more minutes since I had changed the hydro oil and also engine oil.
Here is what I have now, the brake pedal is still locked wont move up or down also the transmission will not engage on the left side of the shifter panel but will engage an move the tractor on the right side of shifter panel which includes 3 and R and 5 and R. Any ideas would be appreciated. Also I need to mow would I be safe to use the 3 or 5 which are what I generally use anyway or will it burn something up. And it would really be great to get the brakes working.
Oh and once while pulling someone out of the snow it seemed like one wheel wanted to lock up. What about the differential lock pedal? If it was to get pushed could this be my brake issue?
