I would change the hydraulic fluid and filter.
Run it around the yard for 3-4 minutes, then change it again.
And hope that saves it.

worked on getting the hydro broke down to get to the filter to change it out. noticed one of the seven piston was lower then the other . you guessed it broken spring at its foot . the piece of spring went through the system scoring all the mating surfaces and passages . will see if I can clean up surface scars put back together and hope I don't need to buy anew pump assembly . thanks herler for your input ,now I know what the problem is . wonder what caused that spring to break like that , i'll have to investigate that further before investing any more time and money
