Abstract
This research aimed to study some of the technical indications including the use of three kinds of potato diggers (Japanese plow, Chain and spindle type) under loamy clay soil conditions and depth about 15cm and four traveling speeds (1.71, 2.27, 2.56 and 3.41)km/hr. The results were analyzed statistically using the RCBD with split plot design with three replications. The main results of this study were follows: The local equipment (Japanese plow) showed significant effect on the studied properties when registered high weight of total pods, big size pods and undamaged pods with small weight of broken, search and unlifting pods. The travelling speeds of machines used showed no significant effect on studied properties.
