HiCustomer Thank you for asking your question on Just Answer. The other Experts and I are working on your answer. By the way, it would help us to know:
-Could you explain your situation a little more?

can you give us more detail? does the engine sound like it is loading up when you put it in gear? or try to move an implement?

Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.

machine makes no attempt to move or work any hyd cylinder,shows no load on motor. i used backhoe and parked it, an hour later i went to move it and nothing happened. i thought the hyd pump quit so i had it rebuilt and still no hyd pressure anywhere.
Expert:  catmech69 replied 6 years ago.
yeah this is a weird one! one more question on my part ... does it have a clutch?
Customer: replied 6 years ago.
yes with auto style shifter,clutch only needed for start or reverse direction.
Expert:  catmech69 replied 6 years ago.
We need to verify that the clutch is actually engaging..with the engine running when you step on the clutch does the engine change sound of any kind?
Customer: replied 6 years ago.

how does clutch affect hyd system. i dont think there is any change in engine sound

Expert:  catmech69 replied 6 years ago.
well sir the clutch could disengage the hydaulics,you mentioned that you also have no forward or reverse movement of the tractor correct? I will be honest Im not familiar with your equipment, but I know equipment, im willing and trying to help you as an experianced technician, and my understanding is that you have basically lost ALL working functions of your tractor..if that is correct that tells me that we lost our main route from engine to hydaulics and transmission.. so the problem lies somewhere between the 2 points, are you following me? you need to make sure that the crankshaft is turning the device's that are attached to it.. IE hydaulic pump or transmission....

usually with a clutch driven device you can hear the engine "pick up" the load when you release the clutch... even if it is just the clutch load that you are applying.

GOOD LUCK

hyd pump is run off crank and turns with the motor running,my whole system gets pressure from the pump,steering,trans and hyd system,but i have no pressure anywhere.
