Abstract

We have developed rotary-type puddling harrows that had the high performance on residue burying, soil pulverizing and leveling, by installing a new rake in front of the rear cover and improving the arrangement of the blades. Based on the results of this study, these harrows have been commercialized and are utilized for puddling. In this report, we presented the following results of fundamental tests about the large rake. (1) A good average clearance of the large rake teeth in the lateral direction was 37 to 45mm. (2) It was better to adjust the mounting positions of a large rake according to the soil conditions.
