700 h

2004 700H 5600ish hrs Fired up this morning, went to work Right off the bat machine is pulling to the right noticeably. Put back in park, checked controller window, showing code F3A0. Was no service code light on dashboard, I thought that was odd . Turned machine off, cranked it back up. When I did there was distinct humming coming from what I assume was one of the pumps . Never heard it before, and didn't hear it first time I started today. lasted less than a second. machine ran fine for about 30 minutes, then came to dead stop. Service code light came on, F3A0 . Now ive got no movement whatsoever. Shut it down and limped back to house . Had to restart it 10 times or so and go through same process to get it back. Sometimes forward would work, but not reverse. Sometimes opposite. Every time I cranked it back up, I would hear the distinct humming sound, again, assuming from one of the pumps. Pulled floor plate and checked connection on top of the pumps, appears to be good. no obvious broken wires ect. Machine used probably 20 hrs a week, so does sit for short periods unused, but never more than couple days. Any help is appreciated
