L781 left side will not stop after engage steering stick

New holland L781 I was using the skid steerer and after awhile the left side got sluggish and finally would barely move so I checked all fluids and let sit over night the next day I get onit and crank it and the left side drive took off I couldn't stop it. Killed the motor and cranked back up the tires didn't move I thought I had it fixed but wich ever way I move the stick that's the way the wheels turn and there is no way to stop it unless you turn motor off. Crank it up again same thing if I push forward the tires stay forward if I cut motor off and crank it again and pull reverse the tires stay in reverse. Any suggestions?

Take the seat out and move the levers and see if the linkage is still attached or if a bushing is worn out. Also the arms which clamp to the hydro pumps shafts can come loose or break.
