Claim:
1. A method for controlling weight distribution in a self-propelled agricultural implement for delivering liquid or dry product to an agricultural field, the method comprising: storing liquid product in a liquid product container removably mounted on a self-propelled agricultural implement for delivery of the liquid product onto an agricultural field during a liquid product application session, the liquid product container having a front section arranged relatively closer to a front end of the implement and a back section arranged relatively closer to a back end of the implement when the liquid product container is mounted on the self-propelled agricultural implement; storing dry product in a dry product container removably mountable on the self-propelled agricultural implement for delivery of the dry product onto an agricultural field during a dry product application session, the dry product container having a front section arranged relatively closer to the front end of the implement and a back section arranged relatively closer to the back end of the implement when the dry product container is mounted on the self-propelled agricultural implement; mounting one of the liquid product container and the dry product container on the self-propelled agricultural implement; determining target front-to-back weight distributions of the implement for one of the liquid and dry product application sessions in response to one of the liquid product container and the dry product container being mounted on the self-propelled agricultural implement; sequentially emptying the front and back sections of the liquid product container mounted on the self-propelled agricultural implement by delivering product from one of the front and back sections of the liquid product container before delivering product from the other one of the front and back sections of the liquid product container such that an actual front-to-back weight distribution of the implement during the liquid product application session to approximates the target front-to-back weight distribution of the implement for the liquid product application session whereby the differences between the actual front-to-back weight distribution of the implement during the liquid product application session and the target front-to-back weight distribution of the implement during the liquid product application session are attenuated; and sequentially emptying the front and back sections of the dry product container mounted on the self-propelled agricultural implement by delivering product from one of the front and back sections of the dry product container before delivering product from the other one of the front and back sections of the dry product container such that an actual front-to-back weight distribution of the implement during the dry product application session approximates the target front-to-back weight distribution of the implement for the dry product application session whereby the differences between the actual front-to-back weight distribution of the implement during the dry product application session and the target front-to-back weight distribution of the implement during the dry product application session are attenuated.
