ABSTRACT:
The drill rate calculator is used to test seeds per acre population settings for agricultural grain drills. The improvement is comprised of five parts. The two positioning springs are attached to the seed metering cup mounting bolts, and generally are not removed after completed tests. The base cone, which has detents on each side for positioning, confines measured seed to a particular seed metering cup. The seed measuring tube has predetermined seed measuring lines strategically located above a base line from which all measurements begin and test results are determined. A top funnel is used to assist in filling.
