Abstract

A singulating device (171) for singulating granular material in an agricultural implement comprises a metering member (1714), which is movably arranged in a meter chamber (1710) and which presents a plurality of through holes (1715, 1715a, 1715b), which are arranged along a direction of movement of the metering member (1714). The through holes (1715, 1715a, 1715b) are provided as at least one first row of holes and at least one second row of holes (1715, 1715a, 1715b), said rows of holes extending in parallel along the direction of movement. The rows of holes (1715, 1715a, 1715b) are spaced from each other in a direction perpendicular to the direction of movement. The singulating device (171) is connectable to a pressurization device (16), for providing a pressure difference across the metering member (1714), sufficient to cause granules of the material to attach to the metering member (1714) at the holes (1715, 1715a, 1715b). The singulating device comprises an excess material pickup prevention device (17161, 17162, 17163). The excess material pickup prevention device (17161, 17162, 17163) is operable only in an area radially between said rows of holes (1715a, 1715b). There is disclosed an agricultural implement comprising such singulating device and a method of operating a singulating device.
