“…ANNs have been used to solve a wide variety of application in Geomechanics and Rock Engineering [8]. In the last few years, fuzzy inference systems (FISs) began to be used in the areas of rock mechanics and engineering geology [9][10][11][12]. According to Setnes et al [13], an interesting and perhaps the most attractive characteristics of fuzzy models compared with other conventional methods commonly used in geosciences.…”

“…To move the cut soil in the case of cup tooth, gravitational force (F g ) should be calculated, while to get the total force (F T ), gravitational force should be added to resistive force (F s ) as, (6) and calculations provide F T = 196.842 N (for one cutting tooth).…”

“…The performance of a trencher [5,6] is expressed by its production (excavation) rate and by the bit consumption (due to wear and breakage). The production rate, i.e., the volume of material excavated per hour, affects the time necessary to excavate a trench.…”

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.

“…The values of VAF closer to 100 % indicate low variability and consequently better prediction capabilities. The lower the RMSE, the better the model performs [62,63]. In ideal condition, the value of RMSE should be zero and value of CE should be unity.…”
