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.
Claims13
A bed renovator frame having at least one a soil loosening assembly, the soil loosening assembly comprising:
- a rigid shank fixed beneath the frame;
- and
- a blade assembly fixed to the shank, the blade assembly comprising a pair of blades extending horizontally from either side of the base of the shank, wherein:
- each blade has a leading edge angle of approximately 30° from a rear centreline of a direction-of-travel axis;
- each blade comprises a lateral rearward span at right angles to the direction-of-travel of approximately 350 mm;
- each blade defines an inner edge aligned with a direction-of-travel axis being approximately 350 mm;
- and
- the shank is fixed to the renovator frame to draw the blades beneath a soil surface at a fixed depth of approximately 250 mm to sever rootstock at the level of the blades while retaining the rootstock substantially in place and loosen soil above the level of the blade assembly without substantial soil disturbance or inversion.
