When i parked the combine under the shed after cutting wheat my hydro power seemed normal. Come time to cut corn i serviced it and put it in the field but the hydro seems real week on the machine. Haven't changed nothing its like it did it just sitting under the shed.

Throw a 10000 psi gauge on the test DR's on the hydro motor. At full throttle hold the brakes and push the hydro lever all the way. You should see around 6600 to 6800 psi fwd and rev. If it's low, check/replace the pressure control valves in the endcap of the motor.
