Ivan49--being new to tractors and hydraulics, the 4 main hoses from the controller to the frontend loader look bad to me. One of the hoses had already been replaced but its quick disconnect coupler is dripping fluid---about 8 drops or so during the time it takes to cut my back field. The other 3 hoses look brittle and the outside of the hoses are cracked and split on the end that screws into the hard lines on the frontend loader. In the attached picture you can see what I'm talking about. I'm guessing replacing the hoses and couplers may be expensive?
