Abstract:
A tooth assembly for a ground engaging implement, comprising:an adapter carried upon said implement and having predetermined vertical design load capacity sufficient to withstand a predetermined large vertical load without failing, said adapter having a forwardly extending tip mounting nose portion; and a replaceable tip having an elongated body with a rearward end portion and a forward ground penetrating end portion, said rearward portion having a rearwardly opening socket cavity adapted to receive said mounting nose portion of the adapter and said forward ground penetrating end portion having a leading cutting edge at its distal end, said forward ground penetrating end portion transitioning from said rearward end portion to said leading edge in a manner so as to provide a necked down portion adjacent said socket cavity of said rearward end portion, said necked down portion having a reduced cross-section sufficient to cause the tip to fail at said necked down portion when said tip is subjected to a sufficiently large vertical load, such sufficiently large vertical load being smaller than the predetermined vertical design load capacity of the adapter so that the tip will break before the adapter.
