MARKER FOR WORKING VEHICLE

PROBLEM TO BE SOLVED: To provide the marker for a working vehicle by solving problems that a conventional marker for marking rough standard lines of processes during a seeding work, a fertilizing work and the like is operated to be ascended or descended in turning the implement by getting off a tractor or using a power cylinder and the former is inefficient caused by behaviors for getting on and off and the latter is expensive. SOLUTION: In a constitution in which the working vehicle is installed to the tool bar of a working vehicle and the marker for the implement for marking rough standard lines of working processes on a filed is attached to the both sides of the tool bar, the marker for the working vehicle consists of a tool bar-mounting unit, an arm unit and a line-drawing unit. The arm unit is pivoted to the tool bar-mounting unit to be rotative around a pivot shaft. The pivot shaft is constituted to incline forward from the vertical line in lifting the working vehicle and backward from the vertical line in lowering the working vehicle. A device for changing the mounting angle of the arm unit is installed to the tool bar-mounting unit.
