Abstract: A working vehicle attachable an implement such as front loader includes a steering wheel, a steering column frame which supports the steering wheel and has a shape that is long in lengthwise direction, a joy-stick control lever which is disposed in a lateral side of the steering wheel, and a valve which is disposed on an outside face of the steering column frame and is connected to the joy-stick control lever. Accordingly, since the valve is disposed on the outside face of the steering column frame, it becomes easy to perform an assembling work, maintenance check work and the like with respect to the valve.

Abstract: A working vehicle attachable an implement includes a steering wheel which is disposed in a rear side of an engine hood covering an engine compartment for accommodating an engine, a control panel which is disposed near the steering wheel, a joy-stick control lever which is disposed in a rear side of the engine hood and in a lateral side of the steering wheel, a valve which is disposed in the rear side of the engine hood and is connected to the joy-stick control lever, a top cover which is disposed below the control panel, a bottom cover which includes a portion standing up from a floor surface and is a front portion of a floor part, and a middle cover which is disposed between the top cover and the bottom cover, wherein the valve is covered by the top cover and the middle cover, and the middle cover is detachable.

Abstract: A working vehicle includes: a cabin; an air conditioning unit disposed at a rear upper portion of the cabin; and drain hoses connected to a drain portion of the air conditioning unit, water drained from the drain portion flowing through the drain hoses, wherein the drain hoses are respectively disposed at both left and right sides of the air conditioning unit in front and rear direction, and both front and rear portions of the drain hoses are provided with drain hose outlets from which the water flowing through the drain hoses is drained.

Abstract: A grafted seedling producing device including a stock seedling holding unit that holds and conveys a stock seedling, a stock cutting unit that cuts the stock seedling held by the stock seedling holding unit, and a joining unit that joins the stock seedling conveyed by the stock seedling holding unit and a scion seedling, the stock cutting unit including a stock cutter unit that includes a stock blade for cutting the stock seedling by a predetermined stock cutter trajectory, the stock seedling holding unit holding an embryonic stem of a seedling for grafting at a predetermined position on the stock cutter trajectory in a vertical posture, the grafted seedling producing device includes: a supporting unit configured to retract the stock cutter unit from an advance position for cutting in proximity to the stock seedling holding unit; and a stock pressing member that presses and fixes a portion ahead of a cutting position of the embryonic stem from a seedling holding position against the stock seedling holding uni

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.

Abstract: A working vehicle includes a HST, forward and reverse pedals, a brake pedal, an intermediate link mechanism (ILM) operating in linkage with operation of the forward or reverse (F or R) pedal, a single shift rod receiving the operation from the ILM and rotating a trunnion shaft of the HST to a forward drive side and to a reverse drive side, a neutral return mechanism (NRM) having a cam plate rotating integrally with the trunnion shaft and forming a curved surface portion, a roller moving in contact with the curved surface portion, a lower return arm configured integrally with a return arm that includes the roller, and a first spring acting in a direction of returning the trunnion shaft to a neutral position, a lower return arm onto which the first spring is latched, a F pedal onto which is latched a second spring acting in a direction of returning the trunnion shaft to the neutral position when depression operation of the F or R pedals is not being performed, an ILM including a damper applying a resistance to

Abstract: Disclosed is a working vehicle capable of working and driving in stable condition while suppressing the adverse effect caused by the load variation such as sudden dashing from an associated ground working implement. The working vehicle comprises a controller for controlling the variator ratio of its toroidal mechanism to oppose the variation of the load when the toroidal mechanism is loaded on its output side. The controller adjusts the variator ratio appropriately when the engine starts.
