FIELD: agriculture. ^ SUBSTANCE: implement consists of a frame with support wheels and the following components mounted onto it: rotary-type tools with a ridge-like deflector installed between them, coverers and slide boards. Over the rotary-type tools there is the deflective-and-directive cover plate mounted. The ridge-like deflector is represented by rods of periodically varying length attached onto its edge and is equipped with a vibratory movement drive. Over the ridge-like deflector there is the clod smasher mounted. The clod smasher is composed of two reciprocally rotating wound rollers mounted so that to enable adjustment of the clearance between them. On the sides the clod smasher is framed by adjustable tilt angle slide boards. ^ EFFECT: design solution eliminates the risk of vulnerable shoots being accidentally damaged and enables formation of the optimum profile cover mound thus ensuring better clonal stock rooting. ^ 3 dwg |
