To provide a farm working
machine and a farm working method capable of forming a proper
ridge.SOLUTION: A working unit (C) that is provided at a position offset to a side of a traveling
machine body and performs
ridge forming work includes a banking portion (H) that supplies soil excavated by an excavating claw H13 disposed on a rotating rotor shaft H16 to a
ridge forming location, a ridge forming portion (D) that is disposed behind the banking portion (H) and presses the banking to form a ridge (P), a cylinder that causes the rotor shaft H13 to protrude and retract relative to the ridge, and a sensor J1 that is capable of measuring distances to ridge side surfaces in front of the banking portion (H). The banking part H is provided with a cylinder for relatively projecting and retracting the rotor shaft side J1 with respect to the
levee according to the distances measured by the sensor side H13, and the excavation claw side H16 is attached so as to project in the direction of the
levee provided in the banking part D, and moves so as to approach the
levee side when the levee side surface in the advancing direction of the agricultural implement advancing along the levee is recessed, and separate from the levee side when the levee side surface in the advancing direction is projected.SELECTED DRAWING: Figure 1
