摘要： PROBLEM TO BE SOLVED: To prevent dangerous fault in the disconnection of a position detector for electrically detecting the operating angle position of a steering operation tool for performing the steering turn of a combine or the like. SOLUTION: The combine or the like having a traveling transmission case that can execute turning operation by each turning mode and steering operation in straight advance by a planetary gear mechanism or the like via an auxiliary transmission part, is provided with a notifying means for notifying with alarm sound, voice or display when detecting a current non-flowing state caused by the disconnection of the position detector for electrically detecting the operating angle position of the steering operation tool for allowing the execution of each turning operation and straight advancing steering operation by tilt operation; a rotating speed increasing means for increasing the rotating speed of a traveling drive system on the turning inside which is slowing down; a turning restraining means for inhibiting the execution of turning operation even if tilt-operating the steering operation tool; and a substitution detecting means for setting another substitutive means as the position detector.

摘要： PROBLEM TO BE SOLVED: To eliminate a problem that a large number of part items are required to increase a cost with miniaturization incapable of a vehicle due to a constitution providing a transmission gear transmitting power to a drive shaft in an axle case and a brake device braking the drive shaft respectively in the right/ left of the shaft extended from a bevel gear, in the constitution mounting the axle case in right/left both side parts of a transmission case in a tractor or the like. SOLUTION: A differential gear 60, 61, 62 generating a right/left rotational difference in a crawler is provided in the right/left axle case 4, and a right/left drive shaft 5, 5 internally mounted in the right/left axle case is constituted in a single axial state. A pinion gear 6 transmitting rotational power of an engine and a bevel gear 7 meshed with this pinion gear 6 are arranged in a right/left almost central position in the transmission case 2, and a transmission gear 9 transmitting power to the drive shaft 5 is provided in one side part of a support shaft 8 supporting the bevel gear 7.

摘要： PROBLEM TO BE SOLVED: To surely turn at crawling advance of a travel device and avoid a misoperation at turning. SOLUTION: A turning HST5 of this travel device is constituted of a turning hydraulic pump 5a receiving driving force from an engine E, and a turning hydraulic motor 5b for transmitting power to a differential gear device 6 by feed oil from the pump 5a. A hydraulic circuit 5e, which can be opened and closed, is provided between the pump 5a and the motor 5b. The hydraulic circuit 5e is opened and closed in association with tilting of a steering lever 10. When the steering lever 10 is in a neutral position and the hydraulic circuit 5e in the turning HST5 is opened so that the hydraulic circuit 5e from the hydraulic pump 5a to the hydraulic motor 5b is opened, a stop condition of the hydraulic motor 5b is maintained and a machine body travels straight. When the steering lever 10 is tilted to close the hydraulic circuit 5e the hydraulic motor 5b is promptly driven and the machine body can surely turn even at low speed traveling.
