It is configured to be opened and taken out of the machine from above.

``Problem to be solved by the invention'' If the operating column is offset to either the left or right side of the machine, the operator must stand on either the left or right side of the machine. This makes it extremely difficult to perform work such as along the ridge, and if the upper cover of the bale forming chamber is opened upward, it obstructs the worker's forward view, making it difficult to check the work status in front of him. There were drawbacks that made it unsatisfactory.

"Means for Solving the Problems" Therefore, the present invention provides a method for forming the bale formed in the bale forming chamber so as to be taken out in the left and right lateral directions of the machine body, and
The operation control unit for controlling the operation of the machine body is arranged at the center of the left and right sides of the machine body behind the bale forming chamber.

``Function'' According to the present invention, the operation control unit is located at the center of the left and right sides of the machine, and the operator can stand on the left and right sides of the machine as necessary to perform work while clearly checking the working conditions in front of the machine. The upper cover of the bale forming chamber can be opened when taking the bale out of the machine, so it does not obstruct the forward view and allows you to always check the working status in front of you safely. In addition, the work can be performed accurately and safety and workability can be improved.
