SOLUTION: A cylindrical bearing boss part with its axis placed in a lateral direction, a front side connecting plate formed in a state of projecting downward to the front from the bearing boss part, and a rear side connecting plate formed in a state of projecting backward from the bearing boss part, are integrally formed to constitute a shaft support body 67, and the shaft support body 67 is horizontally provided in a casing 20. The inner end parts of lateral center shafts 45L, 45R are coaxially butt-supported by the shaft support body 67, and the lateral center shafts 45L, 45R are positively supported at both ends by the shaft support body 67 and the side walls of the casing 20.

摘要： PROBLEM TO BE SOLVED: To ensure the mesh accuracy of gears by supporting the tip peripheral edge parts of lateral ring gears rotatably fitted to lateral center shafts, by lateral turning gears connected to lateral sun gears and fitted to the lateral center shafts, so as to support the lateral ring gears in a twin state. SOLUTION: Bearing receivers 92L, 92R are formed at the outer peripheral edge parts of turning gears 46L, 46R, and bearing receivers 93L, 93R are formed at the outer peripheral edge parts of lateral ring gears 41L, 41R so as to project onto the lateral turning gears 46L, 46R side. These bearing receivers 92L, 92R, 93L, 93R are arranged in the overlapped state in the radial direction of lateral center shafts 45L, 45R, and bearings 94L, 94R are interposed between the bearing receivers 92L, 92R, 93L, 93R. The outer peripheral edge parts of the lateral ring gears 41L, 41R are thus supported by the lateral turning gears 46L, 46R so as to be supported in a twin state. The mutual mesh accuracy of the gears can therefore be ensured satisfactorily.

摘要： PROBLEM TO BE SOLVED: To enable a device to execute surely and stably a fine turn of a combine by turning operation of a round handle. SOLUTION: In a turn position detection cam plate 200 integrally turned with a round handle 12, a protrusion part 200a is formed, by a right position detection sensor 202, when the protrusion part 200a is detected, in order to execute a right fine turn, a right turning solenoid 80a of a turning control valve is driven by prescribed duty ratio. By a left position detection sensor 203, when the protrusion part 200a is detected, in order to execute a left fine turn, a left turning solenoid 80b is driven by prescribed duty ratio. In this way, an output of a turning second oil hydraulic pump is decreased, by small holding a speed difference between right/left running crawlers, a fine turn is executed.
