Abstract: In order to adjust the sensitivity of an obstacle detection means and improve detection accuracy when an obstacle is actually present although the obstacle detection means detects no obstacle or when no obstacle is actually present although the obstacle detection means detects an obstacle, an autonomous travel working vehicle is provided with a position calculation means for measuring the position of a vehicle body using a satellite positioning system, and a control device for automatic travel and work along a set travel path. The autonomous travel working vehicle is provided with an obstacle sensor, an alarm means, and a false report switch, and if, although an obstacle has been detected and an alarm has been issued, an operator does not recognize the obstacle and activates the erroneous report switch, the control device cancels the alarm.

Abstract: Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The present invention relates to a fuel injection pump which is provided with a pump body and a hydraulic head and driven by an engine, and is characterized in that while the engine is in operation, the temperature of the hydraulic head is increased to a dew-point temperature or higher. Consequently, it is possible to increase the temperature of the hydraulic head and remove water in the fuel injection pump while the engine is in operation. Accordingly, the engine can be prevented from being unable to start in the state that dew condensation occurred in the fuel injection pump and froze.

Abstract: A front loader comprises an arm, a work implement supported to a tip portion of the arm, and an angle display device. The angle display device includes a gauge member, an indicator, a shaft member, and a conversion mechanism. The gauge member has a scale indicating an angle of the work implement relative to the arm. The indicator is movable relative to the gauge member according to variations of the angle of the work implement. The shaft member is movable along the arm according to variations of the angle of the work implement. The conversion mechanism changes a relative position of the gauge member and the indicator according to the movement of the shaft member. The conversion mechanism is configured so as to cause the indicator to rotate relative to the gauge member around a rotation axis being parallel to an axis of the shaft member in one direction or another direction according to the movement of the shaft member.

Abstract: At least an embodiment may provide a remote server that can predict overheating of an engine. A remote server may receives an engine rotational speed, an engine load factor, and a cooling-water temperature. The remote server calculates a moving average of the engine load factor during a predetermine time, and calculates a correlation between the moving average of the engine load factor and the cooling-water temperature. If the correlation during a predetermined period is in the status of a predetermined difference from the correlation up to the predetermined period, the remote server predicts occurrence of overheating in a swing working vehicle that is used by a user.

Abstract: A working vehicle includes an engine, a pair of right and left traveling portions rotated by a power of the engine, a pair of right and left brake operation devices for respectively operating to brake the traveling portions, an engine controller which controls driving of the engine, and a control mode selection switch which can alternatively select the isochronous control and the droop control. The engine controller selects any of an isochronous control and a droop control so as to control the engine. In the case that the isochronous control is designated by the control mode selection switch, the engine is controlled according to the isochronous control when one of the right and left brake operation devices is under a non-operation state, and the engine is controlled according to the droop control when both of the right and left brake operation devices are under an operation state.
