This research aimed to study some of the technical and economical effects including the use of two kinds of potato lifters with one stage of suspended type, the first foreigner made (Finnish) type Tume and the second local designed by the researcher. The research was carried out in mixed soils for both equipments. The angle of lifting was (25) for both equipments and seasons. The results were analyzed statistically by using the factorial experiment with in split plot design with three replications. The following conclusions were depicted. In the first season the results showed that there are no significant differences concerning the effect of lifting equipments on the studied properties In the second season the results showed that there are significant differences concerning the effect of lifting equipments on some of the studied properties, where the local equipment showed slightly higher significance than the foreigner one in the damaged tubers and lifter potatoes properties, but the foreigner equipment showed higher significance concerning the quantitative loss and there were no significant differences in other studied properties. In the mean of the two seasons the results showed that the effect of seasons was higher significantly than most of the studied properties. The first season showed higher significance regarding the undamaged and lifted potatoes than the 2nd season, while the one later showed slight difference concerning the damaged tubers and the qualitative and quantitative losses and no great significant difference in the damaged tubers.
