Controlled population monitor

摘要: The embodiment of the invention disclosed herein is directed to a controlled population monitor which controls density seeds delivered from dispensing hopper furrows formed in field. Seed means associated with direct toward ground and includes seed-sensing apparatus for sensing actually furrow, produce signal corresponding number sensed. A distance sensor provided producing pulses linear travelled are modified times width between rows. produced by seed compared determine whether or not desired being obtained. Should deviate that desired, planting automatically adjusted either increase decrease furrows. This will allow constant be maintained regardless changes planter efficiencies.
