Development and construction of a three-point tethered lemongrass planter

Abstract

This experiment is an experiment to study and develop a lemongrass planter. The research team therefore chose to use the design and development of the machine and compared it with the pre-developed machine. To find the best factors and reduce production costs in growing lemongrass. The factors used in the experiment consisted of 2 factors: 1) Average fuel consumption in the same running distance 2) Efficiency in planting at the same distance but different running speeds was carried out by using gears L2, L3 and L4, engine speed at 1,500, 2,000, 2,500 Revolutions per minute in a total of 27 experiments where the distance of lemongrass plants was 120 centimetres. From all the experiments, it can be seen that the experimental results of the three-point lemongrass planter were the highest efficiency is L2 2,000 Revolutions per minute at 98.72%. The production cost could be reduced after the development of the original machine according to the objectives. using only 1person Planting time was 38 minutes/rai, fuel consumption was 2.34 liters/rai. A total of 27 tests were conducted, using the same distance of 16 meters, using the speed of L2, which had a engine speed of 2,000 Revolutions per minute. 702 plants.
