In one aspect, the disclosure describes an apparatus that harvests crops as the apparatus moves in a direction of travel across a field. The apparatus includes a crop harvesting assembly configured as a line of implements, the line being transverse to the direction of travel. First and second devices for adjusting a vertical position of left and right sides of the apparatus, respectively, are independently operable. Adjustment of a vertical position of at least one of the left and right sides of the apparatus results in tilting the line of implements relative to a horizontal plane defined at a ground surface under left and right ground contacting elements. In other aspects, a method and system are disclosed for automatically positioning a line of implements of an apparatus to follow a ground surface proximate the line of implements.

An object locating system, especially for use in locating a gaming ball in the game of football, utilizes a series of three sensors positioned on one side of a football playing field and a calibration source positioned on the other side. The calibration source emits an ultrasonic signal which is received by the sensors in order to provide a calibration signal. A ball marking unit is positionable on the field at a location of the ball and emits an ultrasonic signal which is received by the sensors and an RF signal which is received by the calibration source in order to turn the calibration source off. The sensors provide signals in which a processing unit calculates time delays by a time acquisition process in order to determine the position of the ball. In an alternate embodiment, the ball marking unit emits only an RF signal which is received by the sensors. The sensors again provide signals which are analyzed by the processing unit to determine delay between receipt of the signals at the sensors. Additionally, an automatic ball marking unit on a track drive can be controlled by the processing unit to automatically provide a visual representation of the ball's location.
