A cultivating machine has groups of soil working tines that are mounted on an elongated support that is driven to rotate about a horizontal axis. The tines are mounted in spaced apart groups and guide members converge at the rear of the groups to form ridges of worked soil. Each group includes tine units that are formed by opposing bracket portions clamped to the support. Strikers can be mounted on the support between groups of tines and the strikers are pivotable about respective horizontal axes spaced from the support's axis of rotation. The strikers are positioned to excise crop leaves or emerged growth on the ridges. Hoods and a grating ensure that the top layer of worked soil is free of debris. Screening plates having obliquely upwardly and inwardly inclined inner edges are located at the lower, front, outer corners of the hood to prevent the rearwardly adjacent time groups from displacing soil too far laterally. |
