A hopper for a seed drill, having: - a hopper wall surrounding a hopper volume on multiple sides; - a partition wall , which is arranged in the hopper volume , separating it into partial volumes, such that a first and a second partial volume are formed, which are separated from each other by means of the partition wall , and are each configured for receiving a granular material such as seed grains, fertilizers or the like; - a first sump , which is associated with a first bottom opening in the region of the first partial volume and is configured for discharging the granular material in the first partial volume from the hopper volume; - a second sump , which is associated with a second bottom opening in the region of the second partial volume and is configured for discharging the granular material in the second partial volume from the hopper volume ; - a wall opening in the partition wall , through which the granular material can pass from the first to the second partial volume and vice versa when the wall opening is open; and - a closure member , which is supported in a pivotable manner in a corner region in which the partition wall meets a bottom of the hopper wall , and which can be pivoted between a first and a second position, such that the closure member - opens the first bottom opening and closes the wall opening when it is displaced from the first to the second position, and - opens the wall opening and closes the first bottom opening when it is displaced from the second to the first position; characterized in that the partition wall has a displaceable wall section , which forms an upper part of the partition wall , which upper part is arranged adjacent to an opening of the hopper located on the deck side, and which, by means of displacing it between a first and a second displacement position, can change a volume ratio between the first and the second partial volume . - a hopper wall surrounding a hopper volume on multiple sides; - a partition wall , which is arranged in the hopper volume , separating it into partial volumes, such that a first and a second partial volume are formed, which are separated from each other by means of the partition wall , and are each configured for receiving a granular material such as seed grains, fertilizers or the like; - a first sump , which is associated with a first bottom opening in the region of the first partial volume and is configured for discharging the granular material in the first partial volume from the hopper volume; - a second sump , which is associated with a second bottom opening in the region of the second partial volume and is configured for discharging the granular material in the second partial volume from the hopper volume ; - a wall opening in the partition wall , through which the granular material can pass from the first to the second partial volume and vice versa when the wall opening is open; and - a closure member , which is supported in a pivotable manner in a corner region in which the partition wall meets a bottom of the hopper wall , and which can be pivoted between a first and a second position, such that the closure member - opens the first bottom opening and closes the wall opening when it is displaced from the first to the second position, and - opens the wall opening and closes the first bottom opening when it is displaced from the second to the first position; - opens the first bottom opening and closes the wall opening when it is displaced from the first to the second position, and - opens the wall opening and closes the first bottom opening when it is displaced from the second to the first position; <EOS>
