How
is the accuracy of the Williames seeder achieved?
First, we make sure that the dibbled hole made to place each seed is in exactly the right place. The hole must be in the centre of the cell and must be at the right depth to suit the particular seed being sown. This is achieved with the timed dibber and specially shaped convoluted dibber points. Second, we give the operator great control over the seeding head so that only one seed is placed in each cell (or if multiple seeds of a low-germination variety are desired in each cell this can be achieved also). This is achieved with the patented seeder head and singulator bars, and on some machines, with variable vacuum control. Williames’ seeders are built to last, to enable accurate high speed seeding year after year. We believe that some of them could have seeded well over one billion seeds since they were first installed. How the Williames seeding head works The diagram below shows how the seeder picks up seed out of the hopper, removes unwanted multiple seeds using fine jets of air from the singulator bars, and places them in the tray. This diagram shows the use of a needle seed drum. How it works
