Mechanical harvesting of two cassava varieties
Abstract: A one cassava harvesting machine is designed and manufactured (under small workshop conditions using locally row materials) for harvesting two cassava varieties. The designed machine consists of digging blade, spikes, shank and mounted frame to suit tractor three hitch points category II.
The performance of the designed machine is evaluated in the field in terms of field capacity and field efficiency, harvesting efficiency, fuel, power and energy requirements as a function of change in machine forward speed and harvesting depth.
Results of this study could be summarized in the following points:
1- The highest buried roots of 10.7 for cassava Brazilian variety was recorded at 4.0 km/h forward speed and 30 cm digging depth, meanwhile the highest buried roots 31.4 % for cassava Indonisian variety was recorded at the same forward speed and 20 cm digging depth.
2- The minimum values of roots mechanical damage of 4.1%, and 3.5% were obtained at a forward speed of 2.6 km/h and 30 cm digging depth in Brazilian and Indonisian varieties, respectively.
3- The optimum conditions of cassava mechanical harvesting using the locally designed harvesting machine were conducted at 2.6 km/h forward speed and 25 cm digging depth for the Brazilian
variety, and 2.6 km/h forward speed and 30 cm digging depth for the Indonisian variety.
