FIELD: agriculture.
SUBSTANCE: bed is mounted in the upper part of the drill drawbar near its hinged joints. The rod of each of the power hydraulic cylinders is attached in the platform of the universal joint yoke with a crossbar which is the head of the bolt axis with a sparse thread extending through the nut guide supported by the angle-plate rest. At the splined end of the bolt axis the I-beam lever with spring-loaded counterbalances is mounted. The device also comprises a clock timer with a sound-light signalling device and the ability to adjust the time parameters of overall switching on and off. The timer is mounted in the tractor cab.
EFFECT: increased productivity, reduced downtime of the drill and time loss during agricultural works.
