| Abstract | ||||
| The main purpose of the present work is to modify a sugar beet digger to suit the Egyptian working conditions using a primary digging tool with a special design (under root) to assist the main harvesting unit to pull the roots from the soil with the following criteria: - The modification should be simple and constructed from cheap row material locally available. The modification should be made from standard components to save the time and money for mass production if possible. It must be designed to attach to the most available tractors. A comparison between the number of un-harvested roots, injured roots and harvested roots were determined before and after modification of the machine. The results indicated that the percentage of un-harvested roots was 16.3 % and 20.4 compared with 5.7% and 4.5% before and after the modification, respectively, at the same tractor speed. While the injured roots were 42.9% and 49.3% compared with 10.2% and 8.2%. The pre-pulling device did not make any change in the machine field capacity but it had direct effect to decrease the number of injured sugar beet roots during the harvesting operation. | ||||
