FIELD: agricultural engineering.
SUBSTANCE: agrobridge has girder mounted on drive cars, platforms movable along girder, agricultural tools mounted on platforms, auxiliary and processing equipment, and cabin with equipment for controlling movement of agrobridge along tracks, said cabin being provided with sighting device. Agrobridge is further equipped with device adapted for controlling coordinate tillage of agricultural land and made in the form of instrument including packet of agricultural land relief-contour maps and reading head block for map scanning. Reading heads are provided with spring-loaded balls and contact plates engageable with plate contacts for spring-loading of said balls. Mechanism for moving balls in vertical plane is made in the form of threaded-gear mechanism connected to roller of drive car. Balls are moved in horizontal plane over relief-contour maps by means of toothed rack, electromagnetic relay and electric contacting mechanism coupled to supporting plate of one of jacks.
EFFECT: simplified construction of equipment for generation and transmission of control signals and reduced costs.
