1. A farming apparatus, comprising:

  • a guidance computer to steer an implement according to a row offset provided by a row sensor with respect to a row;

    a positioning system to determine geographical positions of said implement;

    a row calibrator to calibrate said geographical positions according to a difference between one of said geographical positions and a planned geographical path of said row; and

    the guidance computer to use said calibration with said geographical positions to steer said vehicle, wherein;

    the guidance computer has a first mode to steer said implement to minimize said row offset provided by said row sensor with respect to said row and to steer said vehicle to minimize a hitch offset between said vehicle and said implement; and

    a second mode to steer said vehicle to minimize a cross track error between a geographical path and said calibrated geographical positions where said implement is not independently steered.
