Question
all my hydralics have quit.where is the pump located and how do i get to it and what do i check ?

Answer
First make sure the oil is full, and if it has a filter, change it.  Plug a gauge into  a remote coupler and see if you have any pressure.  If it's very low, it could be the relief valve or the pump.  If there is none, either the pump has failed, or the pump is not turning because of a broken gear or shaft splines that have stripped out.  Early 2000's had a pump on the side of the clutch housing, and later style tractors had a pump inside the rear frame.
