Costco Hydraulic fluid for 50/100 hour Branson 4720 service?

[Texasmark]

Make sure it says" hydraulic/transmission fluid"

4720 Branson should at least have hydro steering and wet brakes meaning that you need to add the word "Premium" to what you said. Look for JD J20C spec on the label, not JD 303 which is the basic trans-hydraulic fluid made for older tractors with a common sump....tranny and hydraulics with none of the current whistles and bells. My Fords run the 303, Bransons the J20C.
