ABSTRACT

Hand tractor is a popular agricultural vehicle in Asia, like Indonesia. Most of the hand tractors are used to soil tillage in paddy fields that are integrated with various types of implements such as plow, rotary, dishes, etc. The challenges a majority of the characteristics of paddy fields in Indonesia is sloping land (with a slope greater than 10°), small in size (5-10 m2 per plot paddy field) and irregular in dimensions between one paddy fields land and another. That requires the performance of hand tractors to be able to work moving between plot paddy fields so that it can achieve all plot paddy fields. Several studies have examined this issue for 4-wheel tractors; however, on the hand tractors have not been studied in depth to date. Therefore, the objective of this study is to analyze the performance of the hand tractor to climbing sloping terrain. The experiment of the field for trajectories of hand tractors is designed with a slope of 10°, 15°, and 30°. The performance of the hand tractor (torque, wheel rotational velocity, forward speed, sinkage, and slip) is measured when the hand tractor climb of the track. Traction efficiency is also calculated to show the level of effectiveness of the hand tractor when climbing of sloping land. The results show that the torque on the hand tractor increases with increasing land slope from 10° to 15°. But after that, the torque will decrease sharply in the condition of the land with a slope of 30°. Wheel rotational speed, forward speed, sinkage and slip of the hand tractor decrease by increasing the sloping angle of the land, respectively. The traction efficiency of the hand tractor also decreases along with increasing sloping terrain.
