A loading operation of a plurality of stages of container W, for example, a three-stage container W group, that is, a replacement operation is performed.

That is, as shown in FIG. 3, for example, the driver of the tractor T performs a predetermined operation to perform the three-point link mechanism T.
The top link a and the lower link b of 1 are rotated to lift the entire farm work machine 1 from the field H to the ground. Further, the operator turns on the lifting operation switch 92 to raise the fork 73 by a predetermined amount, and turns on the turning operation switch 93 to turn the fork 73 by a predetermined amount.

When the fork 73 is raised, the separation conveyor
31 is brought into contact with a container W on the fork 73, which is raised together with the fork 73, and is pushed by the container W to move upward, that is, in the upward direction so that, for example, the rear end side is raised about the rotation center axis α. Rotate a fixed amount. That is, the separation conveyor 31 is pressed by the container W and jumps up.

Subsequently, for example, from the lifted state shown in FIG. 3, the fork 73 is lowered by operating the raising / lowering operation switch 92, so that the lower surface of the pallet P is loaded onto the carrier 1 of the carrier 106.
By bringing the fork 73 into contact with the upper surface of 07 and then moving the tractor T forward, the forks 73 are extracted from the pallet P, and a plurality of container W groups in which the agricultural products A are fully stored are placed on the fork 73 on the pallet P. From carrier 106 of carrier 106
Replace on top. The separation conveyor 31 pivotally returns to a predetermined work position due to gravity of the separation conveyor 31 itself.

After loading a plurality of container W groups, the operator inserts the next pallet P into the fork 73, places the next empty container W on the inserted pallet P, and the state shown in FIG. To In addition, the operator who follows the farm work machine 1 is
