A seed singulator for an agricultural planter uses a housing with a seed cavity to which seed and compressed air is delivered and a disc with seed pockets which, in rotating, pick up seed kernels from the seed cavity and drop them at equally spaced intervals. A wear ring prevents the rotating disc from wearing the singulator housing and a resilient air cutoff pad has radial extensions which extend between sealing surfaces on the housing and the wear ring whereby seeds are prevented from wedging between the air cutoff pad and the side walls of the groove in which the pad is installed. The trailing edge of the air cutoff pad has coplanar segments in angular relation to one another which serve to accurately space the seed when using a seed disc with multiple annular rows of seed pockets.
