Performance of a Triangular Rubber Tracked Tractor in Paddy Fields
AbstractTracked tractors have been commonly used on paddy fields to overcome soft soil problem. However, triangular-shaped rubber-tracked tractors with high clearance has not been properly tested. The objective of the research was to evaluate the performance of a triangular, rubber-tracked tractor used in paddy fields. This tractor was tested in typical paddy field conditions at MARDI Seberang Perai. The prime mover was attached with a rotary tiller. The performance tests include measuring the soil bearing capacity before and after machine disturbance, machine work rate per hectare and the effective field capacity. The fuel consumption was also recorded. Results showed that the tracked tractor obtained an effective field capacity of 0.576 hr/ha with average fuel consumption of 20 liters/ha. The lightweight tractor also contributed in producing less ground effects, combined with the use of low ground contact pressure tracks, that caused minimal soil disturbance that would affect the soil hardpan layer. The tractor had enough power to move in typical paddy field condition, with no soft soil problems. The tractor was able to turn 360 degrees within a small area, which made it suitable for working in paddy fields. This prime mover has potential to be used in paddy fields.
