Last year I changed my filter and fluid in the hydro unit of a Cub 2082 Lawn Tractor. The reason I changed it was the steering would get really hard to turn after about an hour of use. I was told to change the filter and fluid. It fixed my steering problem but ever since It leaks fluid out of a plug on top of the hydro unit. It leaks any time the motor is running and seems to get worse with higher rpm. I used a wix replacement filter and Hydro fluid from Rural King. It was approved for IH hytrans units, or so they said.
Could non Cub fluid be the problem or am I in for a big repair?
