That is not a common problem that I am aware of. If the right steering clutch won't disengage, then the machine will not turn to the right. Same if the brake/steering clutch operating sequence is out of adjustment. The symptoms you describe have been noted in machines that have been idle and stored outside for extended periods.
It would help to know whether it has pendulum pedals or direct link pedals.
