Recognition system for implements mounted on tractors - electronically measures wt. of implement defined e.g. end position, so that driver can switch to appropriate mode

摘要

The identifying arrangement is esp. for tractors with electrohydraulic actuating systems. The implement attached is recognised electronically so that the operator can switch over a control unit to the appropriate control mode or the controller can switch itself over automatically. A measurement sensor determines the mass of the attached implement for a given position and produces a corresp. output signal. The given position may be the end position of the implement. The output signal of the measurement sensor is fed to a threshold switch or a window comparator with an adjustable critical value. The threshold switch or comparator acts upon a memory element which can be set only when the implement is in the defined position.
