This study conducted on the constructed and performance a new sugar beet cultivator is an important production operation that assists in soil loosening weeding between rows and ridge forming. However, the operation is problematic because of risks of damaging the plants during critical growth phases. The article examines a new construction for precision cultivator guidance for inter-row tillage and presents the results of field trials of the new construction. This cultivator allowed for an

This study concentrated on comparing between exported cultivator (model Gaspardo), Italian construction and the developed cultivator, to evaluate the new cultivator, three measurements achieved, weed erasing efficiency (E1 %) -weed control efficiency (E2 %) -percentage of damaged plants (Dp %). The equipment was tested under different operating conditions, at depth of cultivating (3, 5 and 7 cm), tractor forward speed (3.2, 4.4, and 5.5 km/h) and three types of shares (duck leg, shovel and modified share with protection armors). The results showed that the forward speed is 3.2 km/h; depth of cultivating was 7 cm and the modified type of share, respectively due to its ability to level soil loosening, weeding, and ridge forming between rows and reconsolidate the soil. The aim of this work is to study and performance a local inter row cultivator that working twice, the first at 8 -12 leaves and the other after ten days from the first one to be maximizing exploitation by Egyptian investments in new reclaimed land.
