The present invention relates to a plough device (100) and a method for ploughing a ground (120). A rotatable first plate-like cutting element (102) having a circumferential first cutting edge (103) is arranged on a support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a side region (202) of a soil ridge (201) of the ground (120) can be cut by means of a first cutting region (104) of the first cutting edge (103). A second disc-shaped cutting element (105) having a second cutting edge (106) is arranged on the support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a base region (203) of a soil ridge (201) of the ground (120) can be cut by means of a second cutting region (118) of the second cutting edge (106), wherein the second cutting element (105) is arranged relative to the first cutting element (102) in the ploughing direction (110) such that the second cutting region (118) is arranged before the first cutting region (104) in the ploughing direction.

A blade assembly includes an adapter board including a lower tool bit attachment portion, terminating in a lower adapter board free end, the lower adapter board free end defining a bottom surface defining a plurality of shank receiving bores. A plurality of bushings are disposed in a corresponding one of the plurality of shank receiving bores.

This invention relates to a mouldboard for a plough having active and passive surfaces. The active surface arranged opposite to the passive surface and has extensions in vertical and longitudinal directions. Active surface extends from an upper rim to a lower rim of the mouldboard, and, in a predetermined area, has a geometry configured existing of a number of cross-sections spaced along mouldboard's extension in longitudinal direction and intersecting upper rim of active surface and lower rim of active surface so that each cross-section on active surface in the predetermined area defines a cross-sectional curve. In respect of each cross-section and within the predetermined area of active surface, the cross-sectional curve includes upper and lower cross-sectional parts of the active surface. In respect of each cross-section within the predetermined area of active surface, the lower cross-sectional part of a particular cross-section has a smaller curvature than its corresponding upper cross-sectional counterpart of same cross-section.

A cutting edge component for a work tool on an earth-moving machine may include a longitudinally-extending wear component and a support surface connectable to a moldboard of the earth-moving machine. The wear component may include at least one wear portion connected to the support surface, and the at least one wear portion may form at least one ground engaging edge. The at least one wear portion may include a mild steel body and a plurality of longitudinally-spaced white cast iron teeth vacuum brazed along a distal, ground engaging edge of the mild steel body. The plurality of teeth may each be shaped with two intersecting substantially planar surfaces arranged to mate with at least a surface extending between the distal, ground engaging edge and at least one of a rearward-facing surface of the mild steel body and a front-facing surface of the mild steel body on at least one of a side of the mild steel body facing away from a direction of travel of the machine and a side of the mild steel body facing in the direction of travel of the machine to form a brazed joint. Each tooth may include a material directing feature defined in a front-facing surface of each tooth when the tooth is brazed to the mild steel body.

An autonomous farm vehicle is provided. In a preferred embodiment the vehicle is a plow, which is capable of driving itself without input from an operator. The plow is significantly lighter in weight and smaller in size then a combined tractor and plow, and can be operated continuously. The vehicle, includes a chassis mounted on a plurality of wheels and a tool in the form of a plowing assembly mounted to the chassis and displaceable about the chassis between a first and a second position, such that in the first position the plowing assembly is operational while the vehicle is driven in a first direction. In the second position the plowing assembly is operational while the vehicle is driven in a second direction substantially opposite to the first direction.

A method of enhancing the soil structure of land having a topsoil layer and a subsoil layer beneath the topsoil layer includes providing at least one subsoil tiller blade having a tilling surface and a bottom end, and a channel positioned behind the tilling surface of the subsoil tiller blade for injecting nutrients toward the bottom end of the subsoil tiller blade. The subsoil tiller blade is inserted into the land such that the bottom end extends into the subsoil layer. The subsoil tiller blade is driven through the land such that the tilling surface loosens the subsoil layer while the channel deposits nutrients into the subsoil layer.
