FIELD: agriculture; machine building.
SUBSTANCE: planting machine for forming a trench for planting seeds and/or fertiliser in a ground surface comprises a frame that supports a planting assembly having a cutting tool and a gauge. Said gauge sets the height of the cutting tool so as to determine a depth of the trench formed by the tool. Assembly includes a linkage coupled between the frame to the gauge and an actuator to allow for remote adjustment of the linkage, in order to vary a planting depth of the trench. Gauge and tool are mounted to the frame with a parallelogram coupling. Linkage is mounted directly to the coupling and adapted to raise and lower the gauge relative to the coupling.
EFFECT: invention enables to reduce the time spent on adjusting the depth of the planting trench.
