We have a 2004 Bobcat T180 with about 1100hrs on it. I was working it fairly hard the other day and the hydralics started to get sluggish. When I stopped the loader lifted slow and a little jumpy and if I moved forward slow it would go but if I pushed the levers all the way ahead it sounded like it was trying to work but wouldnt go. The filters were all changed last week except for the little brass inline hyd's ones under the cab so I changed them. Tried again and same thing....after trying several times it now wont do anything. After reading online I decided it could be the hyd pressure sensor as the light would somtimes come on. Made no differance but now the light and buzzer are on all the time. I need to find a guage and check hyd pressures. Any other ideas?? I hope its not the charge pump!!
