Abstract: Provided is a work vehicle having an improved obstacle detection accuracy. The work vehicle includes: a bonnet provided on a front portion of a travelling vehicle body; an obstacle sensor that detects an obstacle on a front side; and a sensor attaching stay configured to extend toward a front side of the bonnet and to allow the obstacle sensor to be attached thereto.

Abstract: A working vehicle may be provided that detects obstacles around a self-traveling tractor in a wide range, with reduced erroneous detection. A tractor may include a vehicle body including a front wheel and a rear wheel; a rear wheel fender covering the front and top of the rear wheel; a rear stay in a shape that extends along the rear wheel fender, a rear first obstacle sensor provided at the front of the rear stay; and a rear second obstacle sensor provided at the rear of the rear stay.

Abstract: A work vehicle includes a hydraulic main speed change clutch and a Hi-Lo clutch provided to a power transmission device for transmitting power to drive wheels, and a speed change control device configured to control vehicle speed in multi-stage manner by a combination of the main speed change clutch and the hydraulic Hi-Lo clutch. In shift-up operation for changing the speed from a low speed stage range to a high speed stage range in which a high speed clutch is used, before completion of speed change, the high speed clutch pressure is kept at a first pressure (Pa) higher than the low speed clutch pressure while the pressure of the main speed change clutch, which is a speed change source, is kept, so that the power is transmitted by a combination of the high speed clutch and the main speed change clutch, which is a speed change source.

Abstract: A work vehicle with a travel control device that allows stationary work without disabling a theft-prevention state of the vehicle is provided. The work vehicle includes an engine, a power transmission device having a clutch for transmitting rotational power of the engine to drive wheels, a travel control device for controlling the clutch in the power transmission device and having a start restriction mode for restricting engagement of the clutch when electrical power is turned on, a mobile terminal configured to transmit signals for enabling and disabling the start restriction mode, and a control unit configured to transmit and receive signals to and from the mobile terminal.

Abstract: A work vehicle includes two types of PTO shafts, a PTO drive unit, a storage unit, a PTO gear shift operation unit, a PTO shaft detection sensor, a PTO gear shift sensor and a control device. The storage unit stores a PTO shaft, which is not connected to the driven portion, of the two types of PTO shafts. The PTO gear shift operation unit performs gear-shifting of the gear shift mechanism. The PTO shaft detection sensor detects a type of the PTO shaft stored in the storage unit. The PTO gear shift sensor detects an operation state of the PTO gear shift operation unit. The control device decides a propriety of a combination of a detection value of the PTO shaft detection sensor and a detection value of the PTO gear shift sensor.

Abstract: A route setting device of an agricultural working vehicle, wherein the route setting device includes a reference-measurement starting switch unit which accepts a setting operation of reference-measurement starting, and a reference-measurement ending switch unit which accepts a setting operation of reference-measurement ending, the reference-route setting unit has a reference-measurement starting setting unit which sets a starting point of the reference-route based on the setting operation of the reference-measurement starting switch unit, and a reference-measurement ending setting unit which sets an ending point of the reference-route based on the setting operation of the reference-measurement ending switch unit, and the starting point is renewed with every setting operation of the reference-measurement starting switch unit.

Abstract: In structure of an engine control device for a tractor, when a standard engine performance curve is selected by a mode selection device, and a PTO drive device, which drives an implement attached to a tractor, is turned on, switching to the engine speed maintenance control mode is performed. Further, when a fuel efficient engine performance curve is selected by the mode selection device, and the PTO drive device, which drives the implement, is turned on, switching to the engine speed change control mode is performed. The problem that an engine stall tends to occur when control for maintaining the engine speed is performed while the fuel efficient engine performance curve with lower consumption rate than normal consumption rate is selected can be solved.
