Abstract
For use with lettuce heads growing in double rows between furrows, there is provided a wheeled cart having a body adapted to be drawn along a furrow and carrying a radiant energy detector and an indicator, printer or readout for the detector, as well as a power supply and auxiliary equipment for the indicator and detector. One or a pair of outrigger bodies are articulated to and movable toward and away from the cart body. Each outrigger body runs between the lettuce heads in one of the double rows on opposite sides of the furrow. A source of radiant energy is located in one or both outrigger bodies and beams through the lettuce heads to the detector. Except when away from the cart body in operating position, the energy source is or the sources are shielded to block release of radiant energy. The source and detector locations may be interchanged.
