description FIELD: agricultural production, in particular, drills and combined units for direct strip drilling of seeds onto stubble and sod. ^ SUBSTANCE: strip sowing drill has frame bearing supporting-drive wheels, hopper for drill equipped with seeding units, seed pipes, seed guides, covering rollers, and rotavation section. Rotavation section has tillage depth adjusting mechanism and is closed with housing. Working devices mounted on output shafts of rotavation section are formed as disks with L-shaped knives. Each of working devices has safety coupling consisting of driving half-coupling, driven half-coupling, and intermediate bushing. Driving half-coupling is mounted on output shaft of rotavation section and has radial protrusions provided on its outer surface. Driven half-coupling has radial openings and is equipped with disks. Intermediate bushing has radial cuts and diametrical slots on its outer surface. Each of radial protrusions provided on driving half-coupling is disposed in respective radial cut of intermediate bushing. Compression springs are positioned between protrusions at side opposite direction of rotation. Driven half-coupling is connected to intermediate bushing by means of spring-loaded stops positioned in radial openings of driven half-coupling and in diametrically opposite slots of intermediate bushing. ^ EFFECT: improved quality of soil tillage, provision for direct strip drilling of seeds onto stubble and sod, prolonged service life of L-shaped knives and reduced consumption of power for rotavation process. ^ 2 cl, 2 dwg
