Field test of a locally designed inter furrow cultivator prototypeNabil Shaban
The main aim of this research was to evaluate and test the hand steering cultivator for inter furrow cultivation. The hand machine frame was provided with a single rubber wheel. The soil working tines represented in the two augers attached to the back of the frame. The auger tines mounted to the frame was inclined in position of both sides of the frame. The cultivation unit is supposed to uproot and kill weeds at the early stage of the crop growth along the furrow sides with minimum crop seedlings damage. The cultivation unit also should agitate soil surface and form of the furrows to facilitate easy irrigation. The cultivator was tested in the Faculty of Agriculture, Al-Azhar University, Assiut. The experiments show that using small size auger tines may not mean lower labor effort exerted for pushing. The direction of cultivation tine rotation generates forces directed forward in the direction of motion. Therefore, lower labor fatigue may occur when using auger tines of larger size (suitable for cultivation) and more capable engine to drive it. Possible forward speed for the labor to maintain continuous operation was
0.34 m/s for the labor of average health. This particular forward speed was recorded corresponding to 160 rpm of the cultivation auger tine. The 6 cm lip height auger tine slowed efficient performance of the cultivator from the point of view of soil agitation as well as weed uprooting. Using a ridger efficiently opens the furrow to enable uniform irrigation. The auger tine mechanism was also designed to provide the possibility of changing operation width to match the working conditions of different crops. The theoretical field was capacity 0.21 and 0.29 fed/h. Actual field capacity of 0.17 and 0.22 fed/h were obtained. Operation efficiency was 80.1 and
75 % for Corn and Cabbage, respectively.
