agriculture. SUBSTANCE: apparatus has frame mounted on carrier wheels, which also function as measuring wheels. Frame carries feeding hopper, planting tubes and shares with replaceable shoes (hoes). Planting tubes are equipped with fruit flow stoppers connected to locking plates and are joined to measuring wheels through kinematic chain composed of rotary pin engageable through its lever arm with control cable, whose one end is connected through spring with frame and other end with rotating roller mounted on pin. Planting tubes are made replaceable for sawing tubers of different sizes and are attached with their one ends on feeding hopper, and their other ends are inserted into share cavities. Shares are attached to separate frame mounted on main frame and are movable in vertical plane by hydraulic cylinders. Each share is rigidly fixed to slide mounted on transverse guides for displacement and fixation by stoppers. Planting tubes are made from transparent flexible polymer, which enables operation of apparatus to be visually controlled. Reliable delivery of tubers from feeding hopper into planting tubes is provided through dosing device arranged in outlet branch pipe, which connects feeding hopper to planting tube. Dosing device is made in the form of plate equipped with stop joined to measuring wheels through kinematic chain. EFFECT: simplified construction, enhanced reliability in operation by regulated planting spacing. 5 cl, 10 dwg
