Abstract: An operation control system of a working vehicle capable of maintaining an angle of a bucket at a fixed angle when the bucket is elevated and/or lowered by rotating an arm is provided. The working vehicle includes an arm and a bucket mounted on the arm. The operation control system includes a control unit and a first angle sensor that measures an angle of the bucket. The control unit adjusts an angle of the bucket such that the angle of the bucket takes a fixed angle by referencing the angle of the bucket that the first angle sensor outputs during elevating of the arm and/or during lowering of the arm.

Abstract: An operation control system includes a control device having a hydraulic pump control unit that controls a hydraulic pump based on a level that an operator selects from levels in n stages (n being an integer of 2 or more). The hydraulic pump control unit has operation distance/current value corresponding data where an operation distance of an operating lever and a current value are made to correspond to each other in a corresponding manner with each level in the levels in n stages. A current value that corresponds to an operation distance of the operating lever at a present point of time is acquired from the operation distance/current value corresponding data that corresponds to the level that the operator selects, and controls the discharge amount of a pressurized oil that the hydraulic pump discharges based on the acquired current value.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at a rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. A radially outer end part at an end on an air-flow upstream side of the ring portion is positioned outward in a radial direction of a rotary shaft in the blower fan, as toward the air-flow upstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.
