[Sprocket]

Hey guys, I am new on here and could use a bit of assistance. I have a 2007 430 case skid steer, and nailed a mostly buried steel post that jarred the machine good. Immediately I lost control of the lift arm, but have total control of bucket tilt and drive. Used my emerg over-ride and am able to move up and down but only when over-ride is engaged. Is there a safety sensor in there or any answers? Thanks in advance.
