Got the front tires of my L4600 in the creek, spun down in loose gravel trying to back out, engine died, pulled tractor out on high ground, drained oil from crank case, had maybe a cup to a pint of water in it as the water had been about an inch over the dip stick. water had got sucked into air filter, apparently that's what killed the engine? engine would not crank over with starter? assuming hydrolocked? it was a clear clean creek water, probably in the water 30 min. any suggestions?
