PROBLEM TO BE SOLVED: To improve the efficiency of continuous levee plastering work from one ridge to the next.SOLUTION: A levee plastering machine 1 comprises: an operation part 50 for operating at a side position of a traveling machine body; an angle sensor 58 for detecting the direction of the operation part 50; a position sensor 60 for detecting the position of the operation part 50; a direction cylinder 43 for adjusting the direction of the operation part 50; first and second off-set cylinders 13 and 31 for adjusting the position of the operation part 50; and a control device 70 for controlling these cylinders. The control device 70 has: a normal operation mode in which the operation part 50 operates while maintaining the position and direction of the operation part 50 in a predetermined state; an automatic straight traveling operation control mode in which the operation part 50 operates in a straight line while adjusting changes in the position and direction of the operation part 50; a corner part straight line finishing operation control mode in which the operation part 50 operates in a straight line at an unfinished portion of a field corner; a positioning control mode that changes the position and direction of the operation part 50 after completing the aforementioned mode; and a ridge gathering traveling control mode in which the operation part 50 operates in a straight line when the traveling machine body approaches the next ridge side. |
