ABSTRACT
A method for evaluation of machine performace for terrace construction is presented and tested. According to this method, the channel, the ridge and the original land profiles for each section are obtained. For profile determination, horizontal reference points spaced at 0.5m were used and their respective heights were measured. The differences in height of reference points on the soil surface relative to a horizontal base line made it possible to calculate the cross sectional areas of the channel and the large ridge after each passing of the implement. The suggested methodology was evaluated for terrace making by a crawler tractor and the results obtained were considered satisfactory.
Key words:
