Abstract
A soil sample collection machine has a mobile support frame that is transportable across the soil surface of an agricultural field. A surface scraper assembly is mounted to the mobile support frame and includes a scraper and a driver that is adapted to lower the scraper onto the surface of the soil and move the scraper across the soil surface for removing surface debris before a sample collection probe is driven into the soil at the scraped location and removes a soil sample. A soil sampling probe assembly is also mounted to the mobile support frame and includes a sample collection probe and a driver that is adapted to move the sample collection probe along a downward path into the soil to collect a sample of soil at the place the surface was scraped, to retract the probe upward and then to eject the soil sample from the probe into a container on an endless conveyer of containers.
