| Abstract | ||
| The field experiments were carried out to develop and construct of a local planting machine for the potato crop suitable for Egyptian conditions. The performance of the developed machine was studied under the following parameters: Four different machine speeds of (0.72, 1.08, 1.44 and 1.8 km/h). Three different ranges of diameter tuber about (2 : >4 cm), (4 : >6 cm) and (6 : >8 cm). Three different planting depth of (6, 8, and 10 cm). The performance of the manufactured machine was evaluated taking into consideration the following indicators: void tuber, double tuber, germination percentage, field capacity, field efficiency percentage, concumed energy and operating costs. The machine was designed to be mounted on the tractor’s hydraulic device and carried on two ground wheels. The feed device of the machine consists of two gears and a chain with 16 feeding spoons to transfer potato tubers from the hopper to the soil at regular distances and depths. The experimental results reveal that the highest value of machine field efficiency was 87.2% and highest value of machine field capacity 0.245 fed/h, the lowest value of the energy consumed and the lowest value of the operating cost were 1.29 kW.h/fed and 213 LE/fed, respectively. The optimum operating parameters of the developed potato planter machine were found at 1.44 km/h machine speed, (6 : <8 cm) tuber diameter and 10 cm planting depth. | ||
