FIELD: agriculture, in particular, applying of organic fertilizer into soil from mineral fertilizer windrows. ^ SUBSTANCE: apparatus has tractor with front and rear hydraulic hangers. Windrower mounted on front hydraulic hanger is composed of two sides arranged at an angle to tractor longitudinal axis, and rear wall with dosing window. Organic fertilizer pile leveler adapted for leveling of piles formed after unloading of vehicles is arranged on rear hydraulic hanger. Pile leveler has frame, shaft mounted longitudinally of tractor, and two beams rigidly connected to shaft and arranged in plane perpendicular to shaft. Beam ends arranged at opposite sides of shaft are equipped with fingers. Length of each beam is at least equal to half the width of tractor and half the width of pile. Shaft and beams are rotated through 90 deg in bearings under the action of hydraulic cylinder. ^ EFFECT: reduced draft and power consumed for forming of windrows from organic fertilizer piles produced by unloading of vehicles of any load capacity, improved uniformity of spreading of fertilizer over field surface, provision for employment of heavy-freight vehicles for transportation of organic fertilizer and laying of piles on field surface and, accordingly, reduced number of vehicles demanded for transportation of organic fertilizer on fields. ^ 6 dwg |
