摘要： PROBLEM TO BE SOLVED: To enable an operator to surely grasp the display contents of various kinds of meters and a message given by an informing device while carefully looking at a windshield in front of the operator so as to conduct operation without an error by incorporating a projector for projecting information required for driving operation on a cabin front glass on an instrument panel. SOLUTION: A projecting unit 25 is incorporated in an instrument panel 22 extending all over an operation seat 21. A light source 27, a signal generating part 28, and a light diffraction part 29 are provided in the projecting unit 25, and a signal from the signal generating part 28 is projected on a windshield by the defraction action of the light diffraction part 29. For example, an engine rotating speed and the rotating speed of a PTO are displayed on the front of the windshield. A terminal controller comprising a microcomputer and the projecting unit 25 are connected to each other to project a part of the information obtained by the terminal controller on the windshield 25.

摘要： PROBLEM TO BE SOLVED: To move a cabin back and forth for a car body by supporting a cabin covering a driver seat on the upper side of the car body and a driving part such as a steering handle by parallel link mechanisms oscillating back and forth for this car body. SOLUTION: An opening and closing arm 34 is projected downward from a supporting part 33 at the lower ends of rear links 6 of front and rear parallel links 5, 6 which supports a cabin 4 for a car body 1 and the arm 34 is connected with a cable 35. The parallel links 5, 6 are rotated and the cabin 4 is moved to the front or the rear side by connecting and fixing the tip part of the cable 35 with/to a ground object and by forward or backward driving force due to driving of an engine E of the car body 1. Because the cabin 4 moves, temporaily rising so as to stride over a projection on the car body 1, in the forward rotation moving of the cabin 4, the projection such as an operation mechanism is difficult to be a hindrance and the cabin 4 is capable of smoothly moving back and forth. Thus, maintenance of a driver seat 2 and the upper side of a transmission case on the lower side of this seat 2 can be easily performed.

摘要： PURPOSE:To perform smooth gear shift operation by providing a control part which is constituted in an arbitrary position according to an electric signal so that gear shift is practicable and prevented from performing subsequent shift variation operation for a given short time. CONSTITUTION:The states of sensors and switches, connected to a control part 18, are read and it is discriminated whether shift operation is permitted. In a case it is permitted, when the boost switch 14b of a gear shift switch is pressed, setting to a state wherein an output command is outputted so as to effect shift up to a boosting state by one step is carried out. Simultaneously, a timer to prohibit following shift operation for a given short time is set. Shift variation control is executed, the solenoid 30 of a boosting control valve is charged with a given current and boosting control through which a hydraulic clutch is gradually connected is executed. Thus, a shifter under return to a neutral position and a shifter under movement to a target gear shift position are prevented from being entangled with each other and one shifter is not returned to a neutral position, whereby smooth gear shift is practicable.

摘要： PROBLEM TO BE SOLVED: To shorten shift time if necessary to improve work efficiency while allowing the positive shift operation of multistage shift positions without a sense of incongruity when shifting with the cooperation of a hydraulic clutch type first transmission and a synchromesh type second transmission by the up-down operation of a switch type shift operating part provided at a grip part of a shift lever. SOLUTION: A high-low changeover switch 36 is provided in the vicinity of the shift lever 18 separately from an up switch 34 and a down switch 35 provided at a grip part 83 of the shift lever 18. When the push operation of the high-low changeover switch 36 is performed, the shift position of a main transmission is left as it is, and a Hi-Lo transmission is shifted into a 'high speed' position or a 'low speed' position. Only a hydraulic clutch is thereby driven without performing the synchronization of a synchromesh mechanism by driving an actuator, so that shift operation is performed very rapidly. When the Hi-Lo transmission is in an operable state onto the speed reducing side, a Hi-Lo lamp 83 of the high-low changeover switch 36 is lighted to notify an operator.
