摘要： A ground engaging tip for a seed boot attachment for depositing a seed within a furrow. The tip including a conical shape member formed of three generally planar shape side surfaces wherein two of the side surfaces meet to form an inclined leading edge extending from a tip of the conical shape member; and at least one wear resistant insert. The insert is secured to the leading edge of the ground engaging tip and includes a generally elongated bar having a leading end, a trailing end and three connecting side surfaces, a first side, second side and third side. The first, second and third side surfaces form a bar having a generally triangular cross-section, wherein the leading end of the bar is angled.
