Abstract:
1. A seed distributing machine comprising: a seed meter having a housing to hold a pool of seed to be singulated and delivered sequentially; a seed sensor generating a signal for each seed delivered by the meter and passing the sensor, a seed delivery system to provide at least two different varieties of seed to the meter, the seed delivery system having a switching mechanism to change from a first variety of seed to a second variety of seed being delivered to the meter housing; a controller operating the switching mechanism to control which seed variety of the first and second seed varieties is delivered to the meter based on the location of the machine in a field; wherein the controller stops supplying a first seed variety to the meter before supplying a second variety to allow for substantial consumption of the first variety of seed in the seed pool prior to supplying the second variety of seed to the seed meter, the location of the machine in the field where supply of the first variety of seed to the meter is stopped is based on a programmed quantity of seed representing the quantity of seed in the seed pool and the seeding rate; wherein the controller determines the programmed quantity of seed in the seed pool for each variety of seed during a meter calibration process.
