put gauge on it it read 90lbs 95 at full thottle what is the pressure suppose to be ? thanksYes the hydraulic pump supplies the charge pressure for the hydrostatic drive. Put a 200psi pressure gauge in the port the charge pressure sending unit is in and see what the charge pressure is.
I don't have a service manual for the 731 but the 720 series manual says above 75psi is good. Move the steering levers one at a time and see what the pressure does.put gauge on it it read 90lbs 95 at full thottle what is the pressure suppose to be ? thanks
