hydraulic charge pressure

[brookstown]

i have a jd 9500 combine. When i got it out this year the alarm for the hydraulic charge pressure came on. I changed filters but still have the alarm. Need to know what to do next?

Check PSI at the test ports to see if the problem is low PSI or a defective alarm.

Like Gale said, check pressure first. If the combine propels you are getting enough charge pressure for the pump servo to stroke the pump so pressure check first and go from there.
