Soil cultivating implements

A soil cultivating implement comprising a frame and a plurality of soil working members supported on said frame in a row that extends transverse to the direction of travel, said members being rotatably mounted on corresponding upwardly extending shafts and a driving mechanism engaging each of said shafts to rotate same during operation, said mechanism including a rotary input shaft that extends in the direction of travel of the implement and has a gear in driving engagement with two separate, substantially horizontally extending driving shafts, said driving shafts comprising pinion gear means in driving engagement with said input gear within a gear box, said driving shafts being substantially co-axial and extending transverse to the direction of travel at opposite sides of said gear box, the upwardly extending shafts of said soil working members being drivingly connected to said driving shafts within respective transmission boxes, an upper part of each transmission box comprising a housing for corresponding co-operating gear means that establishes drive from one of the driving shafts to the respective upwardly extending shaft, a lower part of that box forming a bearing housing for a rotatable support for said upwardly extending shaft, lower parts of neighboring transmission boxes being spaced apart from one another by connecting members that house segments of the driving shafts and said transmission boxes being rigidly secured to said connecting members.
