I'm borrowing my uncles 260 skid steer. It is a 2003 or 2004 model with 720hrs. Using it today driving back to house I stopped to open gate and hydraulic fluid was pouring out from right under the center of the machine. No way I poked anything into the hole. Everything works as it should just leaking bad. Any ideas what it may be or where I should start on it? Thanks in advance.
