I guess those big blades are super expensive so they do the work themselves.
Not so much the cost of the blade but the millwright time to take them on and off. It takes less dollars to sharpen them in place than it does dismount one, send it out for sharpening, and then remount it. Plus a good millwright can sharpen a blade pretty quickly, and if you do it a few times a day before it is really dull, it takes even less time to sharpen.
