Abstract
A tiller cover assembly covering a rotary tiller unit is provided inside thereof with rake members arranged at a spacing along the width of cultivation for sieving lumps or blocks of soil carried around by the tiller unit. Each of the raker members is made of a resilient rod which has a coiled portion toward its base end and is fixed to an attaching member at the base end above the coiled portion. The coiled portions of the rake members are projected toward an upwardly or downwardly movable rear cover of the cover assembly, permitting the rear cover to contact the coiled portions. A clearance is formed between sieving portions of the rake members extending downward from the coiled portions to their free ends and the rear cover. A protector is provided on the inner side of the coiled portions, by which the lumps or blocks of soil carried around by the tiller unit are prevented from striking the coiled portions.
