In a herringbone dairy staff can watch the time on the large digital display and know when it is time to take the cups off. If there is enough time left in the row they can leave cows to load and exit at their own pace. In a rotary dairy the large digital time display allows staff to see time losses from stopping, starting, and reversing the platform, and aim to maintain a consistent platform speed. The previous rotation time is displayed to milkers for the first 2 minutes of the next rotation.
