A gate on each container controls flows out to a conveyor system that receives product from each container and transfers same to a conveyor discharge located beside the operator's station. The horizontal distance between a front end of the container vehicle and the conveyor discharge is less than the horizontal distance between a rear side of the furrow opener implement and a front fill opening on the product cart, such that the container vehicle can be driven forward behind the air seeder and the conveyor discharge positioned to discharge into the front tank fill opening while the front end of the container vehicle is rearward of the rear side of the implement. A weighing system connected to a controller allows an operator to control and management of product flow from storage to the field.
