Abstract
A method of maintaining a desired seed population rate during periods of acceleration of the agricultural planter. In one method, if the horizontal acceleration of the planter is greater than a predefined upper threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on a highest stable ground speed. In another method, if the horizontal acceleration is less than a predefined lower acceleration threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on a lowest stable ground speed. In another method, if the horizontal acceleration is less than the predefined upper acceleration threshold and is greater than the predefined lower acceleration threshold, the seed disc is driven at a rotational speed to maintain the desired seed population rate based on an a preferred planter ground speed input.
