I bought a cub cadet 1748 not too long ago. One of the hydros had to be pressed farther forward than the other to track straight. I checked the hydro oil resevior and it was low but I wasnt to concerned. I was changing everything and noticed that unlike my exmark this has two reseviors. The one on the side of the weak hydro was bone dry. I havent really moved or touched it since I bought it. If I refill it will it be ok? How do I tell if the hydro needs replacing? Everywhere that sold hydro oil was closed tonight but I am gonna refill it tommorow. Will it return to normal? Is there something I should do? I am so angry that I was stupid and didnt check both before I bought it.
