This machine would be ideal for:​
This is as especially in demand machine for the residential pool and renovation field. Often access is narrow for getting to the backyard, but the dig depth and volume of earth to move is considerable. Finding a machine that is only 5 feet wide, yet can dig to 13 feet deep (reach is often as big a factor) is a very rare combination, almost impossible to find. Not many other manufacturers ever made such a model, and Bobcat ceased production on this a few years back. The 331E has remained a very desired, and now fairly rare, machine to acquire.
