摘要： A rotary hoe arrangement (10) for weeding a field, the rotary hoe arrangement (10) comprising a tool bar (20) comprising a plurality of hoe wheels (30) along the tool bar (20), two foldable wing sections (40I, 40II) divided by a central bar (25), each wing section (40I, 40II) comprises an inner wing (42I, 42II) connected to an outer wing (44I, 44II) having a distal wing end (45I, 45II), the tool bar (20) having an operational position (22), where the central bar (25), inner wings (42) and outer wings (44) define a straight work line (50), and a folded position (24) where the wing sections (40I, 40II) are folded, each inner wing (42I, 42II) being pivotally engaged with the central bar (25), each inner wing (42I, 42II) pivots in an inner plane between an inner operational position, where the inner wing (42I, 42II) extends along the straight work line (50), and an inner folded position, where the inner wing (42I, 42II) extends vertically upwardly and substantially perpendicularly to the straight work line (50), each outer wing (44I, 44II) being pivotally engaged with the corresponding inner wing (42I, 42 II), each outer wing (44I, 44II) pivots in an outer plane (48I, 48II) being tilted relative to the corresponding inner plane between an outer operational position, where the outer wing (44I, 44II) extends along the straight work line (50), and an outer folded position, where the distal wing end (45I, 45II) substantially faces the central bar (25) and the outer wing (44I, 44II) is parallel to the corresponding inner wing (44I, 44II) and positioned upwardly in the outer plane.
