Abstract

This research aimed to design, construct and test the performance of the rice stubble chopper. There were 2 sets of cutting blade designed for the performance test. The first set of blades was made with approximately 125–130 degrees of curve, 20 degrees of knife-edge slope and used for cutting the rice stubble. The second set of blades was made straight with approximately 20 degrees of knife-edge slope and used to shorten the rice stubble. In order to test the performance, these sets of blades were connected to a tractor via the power transmission (PTO). The speeds of the PTO shaft were at 540 rpm and 750 rpm while the tractor engine was running at 2,000 rpm to 2,500 rpm and the tractor speed were at gear level L2, L3 and L4. The test found that at the average 10–12 centimeters height of the rice stubble, there was not difference between two different speeds, either the PTO shaft or the tractor. The average length of the rice stubble was about 10–12 centimeters long and the SD value was ± 2.10. It was also found that the uneven surface of the rice fields caused the difficulty of tractor control and affected the performance of the cutting blades especially when using a higher speed as the blades move up and down so they could not cut the rice stubble thoroughly.
