A very common problem on that type of tractor was a leak that would develop on the suction side of the mcv pump. There is an O-ring type seal between the center section and the rear frame that is above the normal oil level. With age and repeated heating and cooling cycles the seal will lose it's desired shape and when that happens air may be allowed to enter the hydraulic system. When air gets in the system the MCV pump can lose it's prime and you end up having a hard time to get the steering to work. By adding the extra five gallons of fluid the seal ring will be below the oil level so when it leaks it draws oil into the system rather than air.
