A stone burier for preparation of soil comprising a soil conveyor assembly for lifting a layer of soil from a soil bed, a soil grading means for ending the layer of soil, said soil conveyor assembly comprising a minimum of 1 soil share and an upwardly and rearwardly mobile conveyor; and said soil grading means comprising a forwardly moving grading belt where said belt features a rearward end and a forward most end; whereby fine soil piece fall flat forwardly moving grading belt onto the uncovered soil bed and course soil piece are conveyed forwardly on grading belt to the forwardmost end thereof where they also fall onto the uncovered soil bed, whereby the soil layer is re-laid onto the uncovered soil bed so as that the course piece are becoming to be subsequently covered by and situated underneath the fine piece within the re-laid soil layer after the stone burier passes thereover, further comprising one or a plurality of rotors or tines (T) positioned on the upwardly and rearwardly mobile soil conveyor arranged to interrupt the soil layer because it travels up the conveyor.
