I have a tym 273hst. Used the tractor spreading dirt.Parked it until next day,started it but no hydralics at all.sterring ,loader or 3point will move. Looked at gauge and it was very low filled it up with fluid but nothing moves. Ido not know which pump controls everything. I have one on right side with hoses to loader and two gear pumps on other side. Which one do i need to pull off and how can it be checked? New at tractor repair! thanks Bill
