The adverse effect of using traditional equipment particularly in developing countries is that it is time and energy consuming, less productive, difficult and more manpower is required. Hence, it is necessary to design and produce low price, and simple machines that can narrow this gap. The objective of the project reported in this article is to design and model a light duty trencher that is used for trenching the ground or soil for making ditch, and used for agricultural, ground cabling, ground piping and drainage system. The designed machine trenches, maximum of 1 m depth, 30 cm width and has adjustable length. The working mechanism is fully hydraulic, and equipped with an engine of 12.7 hp, which provides suitable power for the pump that delivers 23 l/min at 1500 rpm to drive hydraulic motors and actuators.
