Abstract
An earth working tooth with wear cap wherein the wear cap has a closed forward end with horizontally extending side wings to mate with longitudinal side grooves of the adapter, the forward end being equipped with forwardly extending side projections to defer wear which would jeopardize the wings and grooves and simultaneously promote build-up of earth to protect the releasable lock between the tooth point and adapter.
