Abstract
Abstract Apparatus for providing information for an agricultural work machine comprising a distance detector which detects the distance travelled by an agricultural vehicle, a fuel consumption detector, which detects the amount of fuel consumed by the engine of the agricultural vehicle, a circuit for inputting the working width of the agricultural vehicle, an operating circuit for calculating fuel consumption rate indicative of the amount of fuel consumed per unit working area, and a display for displaying the calculated information. The fuel consumption detector may be replaced with a timer which detects the working time of the agricultural vehicle so that working efficiency may be obtained in place of the fuel consumption rate. The total area to be worked may be input in order to estimate the time of completion of the agricultural work or the fuel consumption rate at the time of completion of the work. Various function keys may be provided to selectively obtain necessary information among various kinds of information.
