Well i don't own a 773, all i can think of is a bad switch for the tilt solenoid. This would explain the fact you can't move the arms to get out as if the solenoid is pushing oil to your tilt cylinder and you have no pressure left for the arms. Start with the control switch, at least give it a squirt of contact cleaner if you can get access. I'd hate to think what they want for a new one!I sure wish we could edit our own postings? GRR

Check the solenoids with a continuity meter. solenoids are located at the top of the hydraulic control valve under the driver seat. If it is not that then you may have an electrical short somewhere between the hand control and solenoid. Check the service manual for wiring diagrams and info on testing the solenoids.Well i don't own a 773, all i can think of is a bad switch for the tilt solenoid.
