Inter-vine vineyard plough, has radial screw fixed on hole, such that hole allows spring to present high or low pressure for tilting knives when knives stumble on vine stock in their progression

摘要

The plough has a tilt arm (19) provided on a rear part of a fixed structure and equipped with a telescopic rod (20). The rod has an elbow (22) at its lower end, and is fixed with a balance weight unit (23) using the elbow by welding. A cylindrical bent has a contiguous radial protrusion with a wall interdependent of knives (14) of the plough. A radial screw (10) is fixed on a hole in a rim of upper piece of the bent, such that the hole allows an inner spring to present high/low pressure for tilting the knives when the knifes stumble on a vine stock in their progression.
