As the pumps have been tested and you know they are good, it has to be the drive motors or park brake.
As you say if you move the steering levers it will stall the motor, something is locked up.
I assume it's a bobcat S300? they run a wedge and disc brake setup, the coil pulls the wedge up and allows the disc to move, when off, it falls and locks the wheels.
