was conducted by the use of a soil bin test apparatus which enable highly accurate experiments as a part of the study to make clear the tractive performances. Three levels of the wheel weight were chosen as test conditions with some levels of slip. Traction, torque, sinkage and traveling resistance composed of the traveling performances were discussed relating to the wheel weight and the slip. Although the maximum traction increased, the mean traction did not similarly change when the wheel weight increased. It is a cause that the traveling resistance increases accompanied with the wheel weight in consequence of sinkage of the wheel. As a result of such decrease of the mean traction, a tractive efficiency rapidly decreased more than 26% of slip. In this study, the values of tractive efficiency had a maximum one at 14% of slip in spite of the wheel weight and were almost same. The maximum values of the normal and tangential ground contact stresses took place slightly front position against to the vertical center line of the wheel. The angle of maximum stress increased with the increase of slip and had a minimum value at 14% of slip. We have mechanically interpreted a relationship between the angle of maximum stress and the tractive efficiency.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3764"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
