摘要： PROBLEM TO BE SOLVED: To expand ranges of rolling and pitching and to simplify a structure. SOLUTION: A running gear 4 having a pair of right and left crawlers is installed below a chassis frame 1 in a controllable state of rolling to correct the right and left inclinations and pitching to correct the front and rear inclinations by means of a rear link mechanism 12 and a front link mechanism 19. The front horizontal shaft 21 of the front link mechanism 19 is attached to the front supporting attachment member 22 fixed on the frame 1 in a pivoted state. A plate 29 forming the wheel pipe-supporting member of the member 22 situated below the upper crawler 10 of the above crawlers is formed in a slant state that its front side is higher than its rear one so as to become lower as it goes toward the rear side.

摘要： PROBLEM TO BE SOLVED: To increase the tank capacity by providing a tank support part lowered by a step on the upper surface part on the rear end side of a main longitudinal member in the longitudinal direction of a traveling frame. SOLUTION: On the rear end side of a left main longitudinal member of a traveling frame 2, a tank support part 3c is formed extending from a cross member 24c forward to an area where a fuel tank 4 is placed with the upper surface part lowered by one stage. A tank stay 39 having an inverse U-shaped section is joined to the cross member 24c and the front cross member 24d between the left main longitudinal member 24c and the outer left longitudinal member 23b, and the tank stay 39 is formed with the upper surface part lowered by one stage on a level equal to the tank support part 3c. Thus, by the tank support part 3c of the left main longitudinal member and the tank stay 39, the height of the fuel tank 4 installed can be lowered so that even if the height of the fuel tank 4 is limited for the convenience of layout, the tank capacity can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a combine harvester having no longitudinally inclining means but a crosswise inclining means capable of appropriately automatically controlling its own height. SOLUTION: This combine harvester so operates that, when it enters a paddy field from a dry land to immediately lower the front section and a longitudinal inclination detector detects the chassis 2 to descend forward (to raise the rear section), a crosswise inclining means controls the upheaval of the body, when it often descends backward (raises the front section) while traveling on the paddy field, likewise it controls the upheaval of the body, and when the detected value of the longitudinal inclination detector is zero (or a small value), the harvester is judged to horizontally travel on the dry land and the set height of the vehicle is reduced and the body is lowered. The harvester can surely detects a paddy field and keep the height of the vehicle higher, which improves the traveling performance on a paddy field and the operability because of automatically controlling the height. Also, on the dry land, the harvester prevents its height from being positioned higher, never operates while setting its height higher and prevents a trouble of resulting in rugged fields when harvested.

摘要： PROBLEM TO BE SOLVED: To suppress lowering of traveling performance due to collapse of grounding posture of a traveling apparatus by increasing stiffness of right and left main supporting members by connecting members and reducing spreading of the lower end side of supporting leg members due to deformation of main supporting members. SOLUTION: Right and left main supporting members 3 formed long in longitudinal direction are arranged at a prescribed interval on the lower side of a machine frame 2 having an engine supporting part 1 as a first means and space between right and left main supporting members are connected by a connecting member 4 and right and left supporting leg members 6 for supporting traveling apparatus are attached to right and left both sides of the connecting member 4. A vertical supporting part 4v and horizontal supporting part 4h are each formed on the upper sides of right and left both end part of the connecting member 4 as a second means and the inside and the lower face of right and left each supporting member 3 are brought into contact with the vertical supporting part 4v and horizontal supporting part 4h to connect them. Further, a recessed part is formed on the upper side of the connecting member 4 as a third means and an engine discharge pipe or muffler is disposed in the recessed part.

摘要： PROBLEM TO BE SOLVED: To enable to easily steer the rotary handle of a crawleroperating traveling machine such as a combine and improve its safety. SOLUTION: As a handle arm 65 installed below a rotary handle 60 is applied by a tension from right and left by loading springs 77R and 77L, a handle load detected by an operator who steers the rotary handle 60 becomes larger in proportion to a handle-steering angle similarly both in a break turn and a spin turn and a handle-loading motor 71 is operated to bring the tension of the loading springs 77R and 77L larger in the spin turn than in the break turn, thus, the handle load becomes larger in proportion to the handle-steering angle and the spin turn is brought to be able to sense the larger handle load in the spin turn in the same handle-steering angle by preliminary selecting the break turn or the spin turn.

摘要： PROBLEM TO BE SOLVED: To eliminate a sense of incompatibility in operation by automatically transferring from braking turn to mild turn and then from the mild turn to the braking turn when executing the mild turn so that a turning radius can correspond to the tilting angle of a steering lever and clutch connection in spin turn can be made where the tilting of the steering lever is greater than that in the mild turn. SOLUTION: A variable throttle switch 66, a spinning mild executing switch 67, a mild turn cancelling and spin turn starting switch 97 and a mild turn starting switch 98 are fixed to the same body frame. A steering lever 55 is tilted to press the respective switches with an operating member so that braking turn, spin turn and mild turn can be executed corresponding to the tilting angle of the steering lever 55.

摘要： PROBLEM TO BE SOLVED: To adjust the turning direction and the turning angle of a round steering wheel to the turning direction and the turning angle of a machine body when the travelling direction of the machine body is changed by the action of an automatic direction control. SOLUTION: A steering wheel motor 85 is driven while feeding back the sensor output value of steering wheel rotation angle detection sensor 81 according to the timing at which the automatic direction controller brakes a right and left crawler to rotate a round steering wheel. The rotating direction of the steering wheel motor 85 is controlled so that, when the left switch is turned on, the round steering wheel may be rotated right, and when a right switch is turned on, the round steering wheel may be rotated left. The rotation angle of the round steering wheel at the time is enlarged according to the operation time of the brake by driving the steering wheel motor 85 in proportion to the on-time period of the pulse control of a selector valve 76 for the direction control.
