ABSTRACT:
An apparatus for calibrating a conventional seed meter to achieve the lowest error rate of seed spacing and single seed placement per space. The apparatus having an endless belt with cells formed integrally and mounted on a track system with vertically spaced tracks for supporting the belt such that a plurality of longitudinally spaced cells are formed on an upper level for a visible showing of the calibration efficiency. A vacuum seed meter and/or a mechanical seed meter are mounted in side-by-side arrangement such that the outlet of each seed discharge chute of each meter is located directly above and in contact with the upper surface and the slots of the belt and an opening formed in the upper track below the belt and directly below each discharge chute. The apparatus particularly for the vacuum seed meter including further a plate secured to the upper track and extending into the seed meter discharge chute to reduce the chute horizontal length to that of a cell. A reflection device is disposed on the apparatus for making visible the image of a rearward disposed opening to the seed meter for viewing an arcuate portion of the meter seed plate containing seed holding cavities. Additionally, the apparatus has a substitute cover for the original cover usable during operation of the apparatus to provide operator access to the interior of the meter for adjustment of finger tension on the seeds held within.
