I need help finding where it is that you check your hydraulic levels as well as where to drain the hydraulic system. Can anyone help me? I have been under it from one end to the other, followed the lines every which way and can not find anywhere to check the level or drain it out. I have a M4700. I am not by any means a tractor mechanic but I am not incapable of doing some simple service procedures myself. I thought this would be one of those simple procedures-but I am stumped.
