<p>A machine (1) such as a seed drill has two hoppers (2, 27). The first hopper (2) supplies material (such as seed) to seed pipes (3). The second hopper (27) supplies the seed through conduits (41) to the first hopper (2) to maintain a desired level of seed in the hopper (2). The second hopper is supported on beams (25) above and ahead of the first hopper (2), and is situated above a soil cultivating machine (17) to which the seed drill (1) is hitched. This position of the second hopper (27) provides favourable weight distribution on the tractor (59) or other prime mover to which the machines are coupled.</p> |
