A cultivator function is coupled with a scraper function in a single implement such that the cultivator portion and the scraper portion of the combination farming implement, when attached to a vehicle, can be mechanically and remotely changed out at any time. The cultivator portion and the scraper portion of the combination farming implement are positioned on opposite sides of a rotating framework, such that the combination farming implement can be mechanically and remotely rotated during use in the field, thus enabling the performance of both the cultivator function and the scraper function without a vehicle operator ever leaving the vehicle.

A soil preparation apparatus having a first frame member configured to couple to a towing vehicle, wherein the first frame member comprises a blade member configured to engage soil. The apparatus can also include a second frame member pivotally secured to the first frame member, wherein the second frame member comprises an adjustable height protruding member configured to engage soil. The apparatus can also include a third frame member pivotally secured to the second frame member, wherein the third frame member comprises a plurality of bars configured to engage soil, and wherein the second frame member pivots relative to the first and third frame members.

A drag bar for levelling of soil includes a rigid frame with transverse bars attached to a tractor by a support head where the frame can be inverted so that a face with aggressive teeth and a smoother face can operate against the soil while the other faces away from the soil. The mounting allows side-to-side movement of a coupling bar which changes an angle of a forward axis of the frame relative to a forward direction so as to incline the bars to move the soil to one side or the other. The support head includes a pair of side-by-side flex cables which allows pivotal movement of the frame relative to the support head. A gauge plate separate from the frame carried on the forks of the tractor runs over the ground to gauge the height of the frame in the levelling action as the tractor moves forwardly.

System that automates crop maintenance activities, such as cultivating and weeding, with a device that intelligently and independently controls two blades that drag along either side of a crop row using sensors to repeatedly track the position of the blades and of the plants in the row. Blades may be moved in and out independently using an actuator for each blade to contour closely around the individual plants, even if plants or rows vary in their positions, and even if plant sizes and shapes differ. An illustrative system may use a single camera and a processor per crop row; the processor may analyze camera images to locate plant positions and shapes, to plan blade trajectories, and to control blade actuators. The processor may be able to control blade movement precisely to respond quickly to sensor input on changes in plant positions, shapes, and sizes along the row.

A surface conditioning drag tool apparatus includes a plurality of fencing members each extending laterally along a width of the drag tool and spaced apart from one another at a plurality of locations between a front end and a rear end of the drag tool. The plurality of fencing members include a plurality of lower ground contacting extremities and a plurality of upper extremities spaced apart from one another in height and a frame coupled with and positioned above the plurality of ground working fencing members.

A land plane that may be moved over an agricultural field to smooth any irregularities in the surface of the field is pulled by a tow vehicle and has a blade assembly in a general diamond shape. The general diamond shape may be between 30 and 35 feet wide and 35 and 40 feet long. Thus, the land plane may have a sufficient length for drag and earth moving capability to economically and properly level a field, and a sufficient width to cover a substantially large area in single pass over the field. Further, the land plane may have foldable wing sections that enable the land plane to be transported over a typical state or county road or highway.
