The picking performance of a 4-row self-propelled riding type rice transplanter was evaluated in the experimental filds at Kasetsart University, Kampangsaen campus under two different field conditions. The first fields was prepared using a rotavator attached to the 22 kW four wheel tractor for both first plowing and puddling operation. The second field was plowed using a conventional moldboard plow and the puddling was done using a raker attached to the two wheel walking type tractor. Planting accuracy of the transplanter was measured in these filds. The missing hills and floating hills in the first field were measured to be 6.33% and 1.33% respectively with no observed buried hills. In the second field the missing hills and buried hills were measured to be 2.33% and 2.00% respectively with no observed floating hills. The soil mechanical properties affected the trans-planter performance were also measured and discussed.
