PROBLEM TO BE SOLVED: To suppress damaging such as bending and curving by making rotational resistance as small as possible and to improve excavating performance even when the rotational resistance is made small.SOLUTION: An excavation agitation device for ground includes a base body 10 fitted to a work vehicle 1; a pair of rotary heads 11 which are provided projecting from the right and left of the base body 10 and supported rotatably by the base body 10; and a plurality of excavation and agitation blades 20 projected from each rotary head 11. Each excavation and agitation blade 20 has a mountain-shaped claw body 22 having a linear ridge 21 atop, and the excavation and agitation blade 20 is provided on the rotary head 11 such that the ridge 21 of the claw body 22 is along tangential directions of circles Qa, Qb having their centers at the axis P of rotation of the rotary head 11. |
