ABSTRACT:
Particular tooth assembly structure is presented for a trench digging machine powered to cyclically present a series of digging teeth as the machine moves forward to dig the trench. The teeth are shaped to produce a semi-circular trench bottom and each is of a size and length such that the power load for digging by each tooth is substantially evenly distributed.
