Abstract
There is provided soil loosening and furrower assemblies and a bed renovator therefor. The soil loosening assembly comprises a blade assembly and wherein the blade assembly is horizontally pitched such that, when drawn beneath a soil surface at a fixed depth, the horizontally pitched blade assembly severs rootstock at the level of the blade assembly while retaining the rootstock substantially in place and loosens soil above the level of the blade assembly without substantial soil inversion. The furrower assembly comprises side plates extending rearwardly from a forward prow edge, wherein the side plates are approximately 25-45° with respect to the horizontal axis; and bottom edges of the side plates are approximately 20-40° with respect to a direction-of-travel axis.
