Hi guys I found an issue with my NH 1630, I just actually bought a small hobbie farm and it came with the farm it used mostly to cut grass, it was the first run I had after I noticed, what looked like fluid (Hydrostatic fluid?) all over the rear tire and on the ground I noticed it was dripping off the lower bolt of the rear axle bearing/gasket housing I removed the rear tire and notice when the pressure was released and the rear axle stopped leaking, is that a bad seal? Or am I missing something plus what is the best way to remove that axle?
