A combination of a soil-working part and a mounting part to be provided on a plough body. The working part has a pair of opposed working tips and is configured to be mounted on the mounting part so that one of the tips is an outboard tip. The outboard tip projects from the mounting part so as to be capable of carrying out a soil-working operation in use of the plough body. The other of the tips is an inboard tip in which the working part has first and second modes of adjustment relative to the mounting part when tip wear occurs. |
