I think the only time a hydro gets fluid is when the drive shaft is turning and rotating the charge pump. I think towing the tractor will turn the out put shaft on the hydro and with no fluid pumped through the pump you damage the ends of the pistons and plates they ride on. I will post a picture later today.Once the swash plates and pistons are damage from the heat created from towing the hydro trans is toast, all the pistons and plates would need to be replaced. That is what happens towing a hydro for to long and to fast. My .02
