PROBLEM TO BE SOLVED: To provide a farm working machine which enables the efficient performance of a border coating operation. SOLUTION: The farm working machine 1 includes a machine frame 2 for being connected to a tractor. A turning frame 11 is turnably attached to a frame attached part 9 of the machine frame 2. The turning frame 11 is composed of a parallel crank mechanism 15 which has a pair of first front and rear parallel opposed links 13a and 13b facing each other in a state being isolated from each other, and a pair of second right and left parallel opposed links 14a and 14b facing each other in a state being isolated from each other. Operating means 21 for carrying out the border coating operation is attached to the turning frame 11. When the tractor advances and swings at a corner part of a field, the operating means 21 carries out the border coating operation while moving rectilinearly along a levee A on the basis of the turning of the turning frame 11 with respect to the machine frame 2, and the turning of the second opposed links 14a and 14b with respect to the opposed links 13a and 13b.
