    I have a 1994 or 95 CASE series1 580SL that came w/"Priority Swing" alot of mechanics and dealers do not know anything about it.When you swing the boom w/foot pedals it really labors the tractors engine,because it kicks both hydraulic pumps in and gives swing cylinders more power.I have tried to get used to it but i wished it was deleted.It seems to make my tractor drank more fuel.I have been told it was a complex and costly procedure to delete.Anybody here have any experiences?Also i am about to change my rearend fluid out my manual recomends a CASE MS1370 fluid which is $95 for a 5gallon bucket,I was also told you could use Hy-Tran Ultra in its place. :help:
