I noticed the drive motor was leaking on the skid steer. Upon further investigation it was the speed sensor that was leaking. These speed sensors were so problematic that Bobcat just did away with them, and re programmed the computer so it wouldn't bring up a fault code. This machine had already been reprogrammed at some point, so it was just a matter of removing the speed sensor, putting a block off plate over the hole and putting everything back together.
