Abstract
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.
Claims18
A ground engaging tip for a seed boot attachment for depositing a seed within a furrow comprising:
- 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 secured to the leading edge of the conical shape member, the insert comprising a generally elongated bar having a leading end, a trailing end and three connecting side surfaces, a first side, second side and third side, to form a bar having a generally triangular cross-section, wherein the intersection of the first side and third side forms a straight edge extending from the leading end to the trailing end and aligned with the leading edge of the conical shape member and wherein the leading end of the bar is angled.
A modular seed planting system including an elongated tool bar supported for movement by a plurality of wheels and which is adapted to be towed in a given forward direction, wherein attached to the tool bar are a plurality of planting units mounted in side-by-side relation relative to each other along the length of the tool bar, each planting unit including a replaceable ground engaging tip, a main body member and a rear seed boot attachment the ground engaging tip releasably attached to the forward end of the seed boot attachment, the ground engaging tip comprising:
- 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 secured to the leading edge of the conical shape member, the insert comprising a generally elongated bar having a leading end, a trailing end and three connecting side surfaces, a first side, second side and third side, to form a bar having a generally triangular cross-section, wherein the intersection of the first side and third side forms a straight edge extending from the leading end to the trailing end and aligned with the leading edge of the conical shape member and wherein the leading end of the bar is angled.
