ABSTRACT:
A ripper tool having a generally inverted "Y" shaped arrangement for use with earth-working equipment such as backhoes, excavator buckets, tractors, etc. The tool comprises a straight shank including means for sturdy attachment to the earth-working equipment and two teeth angled out from said shank towards the ground, the angle between said teeth being from about 38.degree. to 62.degree.. This bifurcated angled arrangement has been found to be both more effective and longer wearing than single tooth rippers or rippers using two or more parallel teeth.
