FIELD: agricultural engineering, in particular, soil tillage equipment used in the gardens. ^ SUBSTANCE: machine has frame mounted on hitching device by means of parallelogram mechanism equipped with hydraulic cylinder. Body of multiple-roll cylindrical reducer is attached to frame. Cylindrical reducer has rotavation drums mounted on upright output shafts. Casing is positioned for rotation relative to central input shaft. Said rotation is controlled by means of mechanism providing rotation of casing through 180 deg during movement around tree trunk. Feeler device is extending around outer edge of frame and adapted for controlling functioning of hydraulic cylinder of parallelogram mechanism through hydraulic distributor. Length of feeler device is equal to spacing between trees in row. Feeler device is oriented along direction of advancement of machine and is secured to frame so that longitudinal axis of reducer casing coincides with mid portion thereof. ^ EFFECT: enhanced reliability in operation and reduced power consumed for providing two adjacent passages for tillage of garden soil strip adjoining to tree trunks. ^ 3 dwg |
