ABSTRACT:
A deep banding knife of the type comprising a bar of metal twisted so that an edge of the bar faces forwardly to define a cutting leading edge and including a material supply duct running down behind the bar for depositing material such as fertilizer into the furrow cut by the knife is modified by the addition of a transverse rod extending through the bar so as to be supported thereby. The rod is of a relatively short extent so that it is supported wholly by and independent of adjacent banding knives. The rod can be attached by a screw threaded coupling arrangement in which one cantilever part of the rod is threaded into a hole in the knife with a second part of the rod screwed onto a male portion extending from the first rod through the knife.
