Abstract: An agricultural machine includes a tractor having a front end, a rear end, and a front frame coupled to the front end. The agricultural machine includes an implement coupled to the rear end of the tractor. The agricultural machine includes a supply line configured to transfer commodity from a front tank, which is configured to be supported above the ground by the front frame, to a main tank of the agricultural machine. The main tank distributes commodity to row units, which distribute the commodity to the soil, and the supply line transfers additional commodity to the main tank. The front frame is movable relative to the front end of the tractor to cause engagement of the supply line with the front tank.
