Monolever operation apparatus for working vehicle and operation method of the same

A monolever operation apparatus for a working vehicle including an arm rest provided at a console placed at least any one of left and right sides of an operator's seat, and a monolever placed in front of said arm rest and rotatively operated in a fore-and-aft direction and a left and right direction respectively,

• said arm rest and console having an outer side, and an inner side, opposite to and adjacent to the operator's seat respectively, in relation to a longitudinal centerline of said arm rest and console, a front side facing toward the front of the vehicle, and a top surface intermediate said inner side and outer side and facing upwardly,
• wherein when operated in the left and right direction, said monolever is allowed to be operated with a distance from a fulcrum of operation below an operator's elbow placed on said arm rest to a grip of said monolever being almost constant,
• wherein an axis of a first rotary shaft for rotating said monolever in the left and right direction passes through the vicinity of said fulcrum of operation,
• wherein said monolever has a palm rest for supporting an operator's palm formed integrally at a lower portion of said grip, and
• wherein in a neutral position, an upper end of said grip is inclined at a predetermined angle so that a side of said grip facing toward the inner side of the console is positioned in front of a side of said grip facing toward the outer side of the console, relative to the left and right direction, and is inclined toward said inner side of the console at about 30 degrees to about 45 degrees relative to a horizontal plane.

A monolever operation apparatus for a working vehicle including an arm rest provided at a console placed at least any one of left and night sides of an operator's seat, and a monolever placed in front of said arm rest and rotatively operated in a fore-and-aft direction and a left and right direction respectively,

• said arm rest and console having an outer side, and an inner side, opposite to and adjacent to the operator's seat respectively, in relation to a longitudinal centerline of said arm rest and console, a front side facing toward the front of the vehicle, and a top surface intermediate said inner side and outer side and facing upwardly,
• wherein when operated in the left and right direction, said monolever is allowed to be operated with a distance from a fulcrum of operation (P) below an operator's elbow placed on said arm rest to a grip of said monolever being almost constant,
• wherein a recessed portion is formed along the fore-and-aft direction on the outer side portion of said console, and
• wherein said recessed portion is formed throughout the range of a maximum stroke during a forward and reverse gear shifting operation of said monolever.
