The performance of developed seedling device for transplanting sugar-beet was tested and evaluated according to the following criteria: Seedlings longitudinal dispersion; seedlings lateral dispersion; and the quality of seedling index. The aim of the present study has been concerned with a particular problem, associated with the sugar beet seedling transplanting. That aim was seen to be achieved through developing a transplanting machine with feeding system of the elastics disc which its idea depend on using rolling press device with to guide to determine the open and close levels. Under forward speed of 0.6 m/s, the best results were obtained using rolling press diameter of 15mm. The theoretical distance was 19.5 cm and the actual distance was 22.45 cm. This was acceptable result as it was in the right limit (the interference is 10%). while by changing the seedling location on the horizontal belt from 7.0 to 10 cm to the highest value of seedling dispersion 7.3% was obtained under forward speed of 1.16 m/s with rolling press diameter of 21mm. The maximum field efficiency of 94.5 % was obtained at forward speeding of 1.5 km/h and the minimum field efficiency of 83.2 % was obtained at forward speed of 4.2 km/h.
