our mid size mini ex is constantly tracking to the right when walking it. Always have to work it to keep it straight. Not being familiar with this machine but is there an adjustment on the pumps or travel motor to tweak to correct problem. I have adjusted out valves before on tandem stacked pumps before on skid steers to correct same issues.
Centre joint leaking?
Good day If you have a hydraulic schematic we can try to help you trouble shoot. Kind regards Uffex
On the travel motor it have forward and reverse valve.( local name) both side travel motor have it. You can either adjust the right side motor valve to slow the pressure and will equal up to the left side
If machine is swinging slow and moving slow on one side travel motor then pump need to adjust. Half of the pump control one side travel motor and swing and the other half control hydraulics and the next side motor
