Turning brakes can be added on. I always have them installed on my hay squeeze. If your loading heavy blocks on ice it's the only way you can steer.
They are manually actuated valves, sort of like a johnny bar, one for each side, only actuates the rear (drive) axle brake. I can't remember exactly how they are plumbed but could find out if your interested.
