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.
Claims19
A furrower assembly comprising:
- side plates extending rearwardly from a forward prow edge, wherein:
- the side plates are each angled backwards at approximately 45° with respect to a horizontal plane;
- and
- bottom edges of the side plates are between 20-40° with respect to a direction-of-travel axis;
- trailing edges of the side plates are configured to form furrow walls being steeper than 70° from the horizontal plane;
- and
- the side plates are configured to form a furrow having a flat base.
A furrower assembly comprising:
- side plates extending rearwardly from a forward prow edge, wherein:
- the side plates are each angled backwards between 25-45° with respect to a horizontal plane;
- bottom edges of the side plates are between 20-40° with respect to a direction-of-travel axis;
- a shank;
- a clamp for clamping the shank to a horizontal frame member;
- and
- a shank height adjustment mechanism, wherein
- the shank height adjustment mechanism comprises a pair of vertically orientated plates engaging the shank therebetween and wherein an edge of the shank comprises height adjustment notches configured for engaging bolts passing through the vertically orientated plates.
