Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a backhoe attachment that is suitable for dredging of grooves, and a track-land dual backhoe.SOLUTION: A backhoe attachment 1 is provided in an arm 6 of a backhoe, and includes a fixing part 11 and a bucket 7. The fixing part 11 is fixed to the tip of the arm 6. The bucket 7 is mounted to the fixing part 11. The bucket 7 is attached to the fixing part 11 so that a yaw angle θ to the longitudinal direction of the arm 6 may become variable. The bucket 7 can set the tip 71 of the bucket 7 horizontally when the tip of the arm 6 is directed downward by adjusting the yaw angle θ. Thereby, even if used for the dredging of the groove at the inclined place, it is hard to leave excavation remainder between the tip 71 of the bucket 7 and the inner bottom of the groove.
