Singulator for agricultural implement, agricultural implement and method of operating a singulator

A method of operating a singulating device, comprising:

• a metering member, which is movably arranged in a meter chamber and which presents a plurality of through holes, which are arranged along a direction of movement of the metering member,
• wherein the through holes are provided as at least one first row of holes and at least one second row of holes, said rows of holes extending in parallel along the direction of movement,
• said rows of holes being spaced from each other in a direction perpendicular to the direction of movement,
• wherein the method comprises:
• providing a pressure difference across the metering member, sufficient to cause granules of the material to attach to the metering member at the holes, and
• preventing excessive material from being picked up by providing an excess material pickup prevention device that is operable only in an area radially or only in an area axially between said rows of holes.

A singulating device for singulating granular material in an agricultural implement, comprising:

• a metering member, which is movably arranged in a meter chamber and which presents a plurality of through holes, which are arranged along a direction of movement of the metering member, wherein the metering member is formed as a cylinder, which is rotatable about a center axis of the cylinder, the holes being present in the circumferential surface of the cylinder,
• wherein the through holes are provided as at least one first row of holes and at least one second row of holes, said rows of holes extending in parallel along the direction of movement,
• said rows of holes being spaced from each other in a direction perpendicular to the direction of movement,
• said singulating device being connectable to a pressurization device, for providing a pressure difference across the metering member, sufficient to cause granules of the material to attach to the metering member at the holes, and
• an excess material pickup prevention device,
• wherein the excess material pickup prevention device is operable only in an area axially between said rows of holes.
