The tail is cut by a tail cutting device while the root vegetables are being conveyed backward.When the root vegetables are guided to the center while abutting the guide guard of the tail cutting device, the conventional horizontally configured member in a front view is obtained. In the guide guard that has
Soil, foliage, tail, etc. are easy to adhere, and if processed in large quantities,
Soil or the like is deposited on the horizontal support portion and the horizontal guide portion that guide the tail of the left and right root vegetables, and at the cutting position of the disc cutter that cuts the tail, the guiding posture is collapsed, and the accuracy of the finished surface of the tail is poor. In each case, an operation for removing soil attached to the guide guard has to be performed, making continuous operation impossible, resulting in poor harvesting efficiency.

In the conventional arrangement, the root of the root vegetable is guided to the center where the left and right disc cutters are wrapped. However, the root is not necessarily guided to the central part in an appropriate posture due to disturbance in the transport of the root vegetable. Not always, the accuracy of the finished surface of the tail was poor. In addition, the conventional guide guard has a complicated structure in which a large number of bar members are arranged vertically and horizontally, so that it is difficult to easily manufacture the guide guard and the cost is likely to increase.
