I have a 4 year old Exmark Quest, that up until today, has been problem free. I mowed 5 days ago, parked it, no issues. Today, I go to start it and the battery is dead....completely dead, weird as the key was off, and the arms were in park...no idea. So I put it on the charger, battery charges up fine, mower starts and I go to move the levers and ......nothing. They just whine. I then check the drive belt, it's fine, I check the tensioner, it's fine and springs intact. With the mower running, I see the drive belt turning and each fan turning at each transmission. Fluid is at the cold fill mark. I then push in on the rods to move it manually, key on, move the levers to neutral. Normally it makes a whine noise for a second when I do that, but it doesn't this time and I can't move the thing manually either. The only other thing I can add is my hour meter,when I turn the key to on, an "8" flashes briefly next to the hours and disappears. Any ideas?
