Abstract: The present describes a work vehicle where an operator can, on the work vehicle side, confirm which working machine is engaged and set which working machine to engage. A tractor, to which a working machine can be mounted, is provided with: a liquid crystal panel selectably displaying an engageable working machine mounted and displaying the currently engaged working machine so as to be identifiable; an operation unit (encoder dial, enter button, and command buttons) for carrying out selection and determination operations for the working machine displayed on the liquid crystal panel; and a control device that, when a determination operation is carried out by the operation unit for a desired working machine, disengages the currently engaged working machine, and configures the working machine for which the determination operation has been carried out to be engaged.

Abstract: A gas-side stop valve on the gas refrigerant side and a liquid-side stop valve on the liquid refrigerant side are provided in a package of an outdoor unit. A gas-side filter on the gas refrigerant side is mounted on the indoor unit side relative to the gas-side stop valve and inside the package of the outdoor unit. A liquid-side filter 9 on the liquid refrigerant side is mounted on the indoor unit side relative to the liquid-side stop valve and inside the package of the outdoor unit. As a result, it is not necessary to ensure a place for mounting the gas-side filter and the liquid-side filter at the time of installation on site and the workability can be improved.

Abstract: A route generating system in which a work vehicle setting unit sets a vehicle information on a tractor. An altitude information obtaining unit of the route generating system obtains an altitude information on a field where an autonomous travel route is to be generated, and a traveling direction setting unit thereof sets a traveling direction of the tractor in the field. A region setting unit of the route generating system sets, in the field, a plurality of regions including a work region where autonomous work paths in parallel with the traveling direction are generated and headlands where connection paths each connecting corresponding ones of the autonomous work paths are generated. The region setting unit sets the widths of the headlands (headland widths) based on the vehicle information, the altitude information, and the traveling direction, the widths of the headlands extending in parallel with the traveling direction.

Abstract: An ECU includes a cooling water temperature sensor, an intake air temperature sensor, a storage unit, a determination unit, and a calibration unit. In an after-run control performed after the internal combustion engine stops, the determination unit compares a cooling water temperature Tw detected by the cooling water temperature sensor with a first threshold value T1 and determines that the environment is not the cold environment in which an EGR differential pressure sensor is likely to be frozen, if the cooling water temperature Tw is equal to or higher than the first threshold value T1, or if the cooling water temperature Tw is less than the first threshold value T1 but is equal to or higher than a second threshold value T2 which is lower than the first threshold value T1 and an intake air temperature Ta from the intake air temperature sensor is equal to or higher than a third threshold value T3, and determines that the environment is the cold environment otherwise. When the environment is determined as not to be the cold environment, the calibration unit obtains a calibration reference value based on the detection value from the EGR differential pressure sensor. The storage unit stores the calibration reference value obtained by the calibration unit.

Abstract: Provided is a fuel injection device for engines, configured using a technique which can extend service life while good responsiveness is maintained. This fuel injection device for engines is provided with: a control rack supported so as to be slidable in an axial direction and configured so that the amount of fuel delivered under pressure by a fuel pumping mechanism can be adjusted by changing the sliding position of the control rack in the axial direction; an actuator which can move forward and backward an operation section; and a link lever which is supported in a rockable manner by a support shaft and which rocks as the operation section of the actuator moves forward and backward, thereby sliding the control rack . The fuel injection device for engines is further provided with an actuator-side connection section for connecting the operation section of the actuator to the link lever. The actuator-side connection section is disposed coaxially with the operation section of the actuator.

Abstract: A tractor in which various main manipulation parts are arranged on the right side of a driver, to allow the manipulation parts and a steering wheel to be reliably grasped with different hands, thus improving workability for the driver; and the various main manipulation parts are arranged within a semi-arc range over which a right arm of the driver turns about his/her right elbow which rests on an arm rest, thus improving workability for the driver and relieving driver fatigue. The tractor includes an operation unit in which a loader manipulation part and a hydraulic manipulation part are arranged near a driver seat disposed at the rear of a steering wheel, the loader manipulation part and the hydraulic manipulation part being arranged within a semi-arc range over which a right arm of a driver turns about his/her right elbow which rests on a right arm rest of the driver seat.

Abstract: An exhaust gas purifier including a casing, SCR catalysts (comprising a first SCR catalyst and a second SCR catalyst), a first backflow prevention plate, and a second backflow prevention plate. In the casing, at least a part of the catalyst passage and at least a part of the bypass passage are formed. The SCR catalysts are disposed in the catalyst passage and selectively reduce NOx included in an exhaust gas flowing in the catalyst passage. The first backflow prevention plate prevents or reduces a backflow of an exhaust gas from a second exhaust passage to the catalyst passage.
