Older JD425 with loader is leaking hydraulic fluid after use. Maybe 2-3 ounces. Coming from around filter area, but any hints as to where common leaks are in this tractor?
 
The pump area has issues with gaskets leaking over time. There is a front cover sandwiched with the pump assembly. There are long bolts and short bolts that hold the system together. Remove the long bolts to remove the entire front assembly together and leave the short bolts in place until removed from transmission. Otherwise you will be retrieving the pinion gear from the rear differential area. Also the brake shaft on the right side has O rings that will leak, and the differential lock lever that has a seal that will slight out over time.
