At the same time, automatic on / off control for stopping the cutting drive of the cutting blade 24 is performed.

  In other words, when the vertical swing position of the work machine 3 exceeds the reference height, the driving of the belt conveyor 23 and the cutting blade 24 is restricted (more specifically, prohibited). On the other hand, when the height is equal to or lower than the reference height, the belt conveyor 23 and the cutting blade 24 are in a non-regulated state in which they can be driven. A state notification lamp (notification means) 69 for notifying the restricted state and the non-restricted state based on the presence or absence of lighting is installed on the operation surface 58a of the operation panel 58.

  Incidentally, in order to realize the above control, a detecting means (not shown) such as a potentiometer for detecting the vertical swing position of the work implement 7 is provided.

  In addition, a notification lamp (notification means) 71 that notifies whether the work lamp 40 is turned on or off based on whether it is lit or not is provided in the vicinity of the work lamp switch 68.

  Further, the transport drive on / off operation tool 63 and the reaping drive on / off operation tool 66 can be turned on / off themselves, and light up when the operation target is driven, while in a state where the drive is stopped. It is configured to turn off.

  The operator A operates the operation panel 58 configured as described above, and performs the work of cutting and collecting the object by the work machine 3.

  FIG. 14 is a side view illustrating a state where the support mechanism is switched to the operation posture, and FIG. 15 is a side view illustrating a state where the support mechanism is switched to the avoidance posture. The support mechanism 59 includes a parallel link 72 that moves up and down without changing the attitude of the operation panel 58, a stopper member 73 that restricts (inhibits) the lifting operation by the parallel link 72 at the highest position of the operation panel 58, and the parallel link 72. And an urging member 74 such as a tension spring that elastically urges the operation panel 58 to the ascending side.

  When the operator A performs a normal operation, the operation panel 58 is switched to the operation posture translated to the highest position by the action of the biasing member 74 and the stopper member 73 (see FIG. 14). Various operations are performed on the attitude operation panel 58.

  On the other hand, when the hull 2 passes through a place where there is an obstacle at a low position from the water surface such as a bridge, the operator A moves the operation panel 58 in the lateral direction against the elastic force of the biasing member 74. It is moved to switch to an avoidance posture that is positioned obliquely downward (more specifically, obliquely downward rearward) (see FIG. 15) to prevent contact with an obstacle at a low position.

  FIGS. 16A to 16C are perspective views showing the state in which the gripping frame is switched from the use posture to the retracted posture step by step. Each of the left and right grip frames 57 connects and fixes a pair of front and rear columns 76 projecting from the deck 7 side of the hull 2, a frame main body 77 bent in a reverse U-shape when viewed from the side, and the front and rear columns 76. A pair of upper and lower lower reinforcing frames 78, 78 extending in the front-rear direction, a front-rear upper reinforcing frame 79 for connecting and fixing the front and rear portions of the frame body 77, and a vertical direction for connecting and fixing the upper and lower lower reinforcing frames 78 to each other. The connecting frame 81 is provided.

The inner shaft 83 is fixed in a state of protruding upward from the deck 7.

  When the outer shaft 82 is moved upward to the extent that the outer shaft 82 is completely extracted from the inner shaft 83 (movable state), the outer shaft 82 can be turned to the left and right with respect to the inner shaft 83 by the connecting tool 84. In a state where 83 is inserted (standing state), it is regulated (prohibited) to turn left and right, and only sliding in the axial direction relative to the inner shaft 83 is possible. Incidentally, the above-described pair of upper and lower lower reinforcing frames 78, 78 are constructed and fixed between a pair of front and rear outer shafts 82, 82, and both are connected and fixed.

  Both end portions of the frame body 77 are inserted into the outer shafts 82 and 82 of the pair of front and rear columns 76 and 76 so as to be movable and adjustable in the axial direction.

  The gripping frame 57 having such a configuration is normally switched to a use posture in which each column 76 stands upright and a part of the frame main body 77 protrudes in the axial direction from the columns 76, 76. Used as a fall prevention application.

  On the other hand, when the hull 2 passes through a place such as a bridge where there is an obstacle at a low position from the water surface, the frame main body 77 is inserted into the outer shaft 82 as much as possible, and each column 76 is made movable and the frame The outer shaft 82 of the support column is switched to the retracted posture in which the outer shaft 82 of the support column is rotated inward in the left-right direction with respect to the inner shaft 83 so that the main body 77 falls on the deck 7 side, and the grip frame 57 is prevented from contacting the obstacle. To do.

  Next, the configuration of the boat maneuvering unit 17B will be described in more detail based on FIGS.
