Abstract
A seed planter performance monitor is disclosed herein. The monitor is used with a planting system including a planter coupled to the tractor. The target rate at which the planter deposits seeds into the soil being planted is controlled with a control signal, and the actual rate at which seeds are planted is monitored with an infrared seed sensor supported by the planter at the location where seeds exit the planter. The planter and tractor both include data busses, and the signal from the seed sensor is transmitted to a controller on the tractor via the busses. The controller applies an appropriate signal to an electronic display in the cab of the tractor to produce an image thereon which an operator can view to determine the actual rate at which seeds are planted. The operator compares the target and the actual planting rates, and adjusts or controls the planter to place the rates in general correspondence by varying planter parameters such as air flow or pressure in the planter, or brush spacing in the drum of the seed meter.
