Development of farm work machine for shaft tillage and transplanting by aged farmer

本研究的目的是研制适合老年农民的农机具。他们可以用农机进行竖耕耕作。研制的农机由竖耕和出苗两个单元组成。苗木供应单元是用市场上链条式盆栽播种机的一些部件制造的。种植试验是由开发的农场进行的。实验的结果，成功率达到了90%左右。播种失败的主要原因是苗木。建议研究更高的播种育苗技术，以提供更均匀的苗木。

The purpose of this research is to develop the farm work machine for aged farmer. They can practice the shaft tillage cultivation with the farm work machine. The developed farm work machine consists of two units for shaft tillage and seedling supply. The seedling supply unit is manufactured using some parts of the chain pot planter on the market. The planting test was carried out by the developed farm. As a result of the experiment, the success rate became about 90%. The factor of the planting failure originated chiefly in the seedling. Then, we suggested the higher technology of sowing and raising seedling must to be researched to supply more uniform seedling.
