=37-Trencher=
Definition – A trencher is a piece of construction equipment used to dig trenches for laying pipe, cable, or drainage. We are building a rock wheel style trencher for trenching in soil and rock.

Problem Statement and Solution– A trencher is a useful piece of equipment for infrastructure-building. We are designing a low-cost, 40 hp version with 3 foot digging depth for about $500 in parts, using the rock wheel design, which is simpler than a digging chain design.
