I have a t190 I just bought from my grandpa. Everything works fine except for the brakes. When unloading from a trailer it will roll down the ramps on its own if I don't apply forward pressure. The parking brake works. When driving forward, if I try to turn slightly, the control gets loose and it is very jumpy as if the drive motor is trying to reverse itself in order to turn. The charge pressure on the display says 264psi at 2700rpm with a fluid temp of 112°F. And 187psi at idle.
