I have lost the hydraulics on my John Deere 1050. It doesnt get much use but about a month ago I tried to widen a drainage ditch. The backhoe was very sluggish. I thought it was probably due to the colder weather but it didnt get any better as the machine warmed up. Next morning I checked the trans/Hydro level and it was low - took almost a gallon ( I know ) . But after filling - there was no hydraulics at all. The pump in front doesnt sound bad and there doesnt seem to be any vibration or grinding when I feel it. To check for pressure , I cracked one of the couplings to the bucket till it leaked a little fluid and then actuated the lever that should have pressurize the line and got no more fluid pressure ( leak ) . An excavator friend said that pumps usually go bad over time, not all of a sudden. I always though it was a little weak but it did always get the job done. Any ideas before I start to pull the front radiator frame and pump apart ? I would appreciate any input or guidance.
