PROBLEM TO BE SOLVED: To provide a bucket with superior agitating and mixing properties and compaction property.SOLUTION: A bucket has a base plate, a back plate and two side plates. Openings for sieving are formed on the side plates and between the base plate and the back plate, while the opening for sieving is not formed on the base plate. Using this bucket enables one bucket to effectively perform multiple processes to plow surface soil, break clods, sieve sediment, level and compact the ground, which results in high work efficiency without the necessity of changing devices for each process.SELECTED DRAWING: Figure 1 |
