Summary:PURPOSE:To improve workability by a method wherein a wheel arranged in a vertical communication ditch in the central part of a chassis is lowered as the wheel is rotated, a ground is excavated by buckets on the outer periphery of the wheel, and excavated soil is discharged to the side by a discharge chute. CONSTITUTION:When a wheel 4 is rotated by a motor 6 and the wheel 4 is lowered by a jack 5, a ground is excavated by buckets 7 and excavated soil is inputted in the buckets 7. When the bucket 7 is positioned above, soil in the bucket 7 is dropped under its own weight and fed through a hole part 4a to a discharge chute 8 and discharged to the side of a chassis 1. Discharged soil is accumulated in a hole part without being scattered. After excavation to a given depth is effected, working of the jack 5 is stopped. When the position of an arm 3 is fixed and a crawler 2 is driven, a chassis 1 is run to dig a ditch 103. In this case, since the bucket 7 is positioned at the central part of the chassis l, stable running is performed. This constitution facilitates formation of a uniform ditch even in a ground where excavation resistance is changed and improves the efficiency of excavation and discharge.
