ABSTRACT:
A seed metering device comprising a seed hopper having a base which is in part sealed by two sets of contra-rotated circular rotary members driven about adjacent substantially horizontal axes, one set of the rotary members having the form of Vee-belt pulleys each of which is provided with a plurality of regularly spaced single seed receptors at the base of its Vee-shaped peripheral slot, the other set of said rotary members having complementray Vee-shaped protruding rims of high friction material penetrating upper parts of the said slots with close tolerance to sweep open faces of the seed receptors, and at least one masking plate mounted in the seed hopper and having an arcuate edge closely spaced from the said open faces of the seed receptors, the masking plate being located beneath the location at which the Vee-shaped protruding rims sweep the said open faces of the seed receptors to maintain single seeds within the receptors until the seeds reach a position at which the seeds can be released from said receptors.
