A crop harvesting header includes a center portion mounted on two spring arms and two separate wings pivotally connected to the center portion. The wings are connected to the center portion by interconnecting linkages which transfer weight from the wings to the spring arms each including a balance beam arranged to balance the lifting force from the spring arm with the downward forces from the center portion and wing such that the downward force on a skid plate of each portion on the ground varies automatically as the total downward force is varied. The balance beams apply force to the linkages by a compression member to reduce forces. The movement caused by floating of the header and the change of angle of the header are compensated at the balance beam to ensure that the force to the wings is reduced as the requirement caused by changes in geometry reduces.

Each of the wheel arrangements includes two parallel wheels coupled together. The wheel arrangement at the rear end includes a second wheel which is mounted on a swing arm so as to be moved to a position adjacent the cutter bar so that the header is stably supported on the first wheel arrangement, the first wheel of the second wheel arrangement and the second wheel of the second wheel arrangement. The first and second wheels of the second wheel arrangement include coupling members for connection together to operate as a common wheel arrangement in the operating position. The swing arm includes a tower which attaches to the cutter bar and can fold down on to the swing arm in the field position.

The invention discloses a spin milling type multifunctional machine for deeply ploughing and crushing ridges, which is based on a tractor. A hydraulic mechanism and a linking spin milling drill bit device or a cultivation component is arranged on a rear frame of the tractor; the linking spin milling drill bit device is provided with one or more drill bit shafts; spiral hinges are arranged on the drill bit shafts and provided with apical teeth; the linking spin milling drill bit device is provided with a device for preventing a straw from being wound; the hydraulic mechanism drives a spin milling drill bit to move up and down; and a gearbox drives the spin milling drill bit by a connecting rod and a gear. According to the spin milling type multifunctional machine, the drill bit enters intosoil and then vertically cuts, spin mills and crushes the soil and ensures that the soil is automatically suspended to form the ridges; the soil crushing section of the crushed ridge is T-shaped; thelower part of the compacted soil on the ground is in a U-shaped groove, so that the whole layer of the soil is in a loosing state during cultivation; and in addition, the invention plays roles of covering and replacing the soil, increases an active layer, improves the capabilities of preserving moisture and fertility and the permeability of the soil, benefits the utilization of deep growing of the crop root system to water and fertilizer, relatively reduces pests and weeds and ensures that the crop is easy to obtain high and stable yield.

An implement has a tongue used to tow the implement that can be raised or lowered with respect to the rest of the implement. The tongue is raised or lowered by a hydraulic cylinder. The raising and lowering ports of the cylinder are connected to two hydraulic accumulators to permit the tongue to flex up or down while the implement is towed through the field. These accumulators are disconnected from the cylinder when the wings of the implement are lifted and the implement is towed over the road to prevent the implement from oscillating backwards and forward about an axis defined by its wheels.

The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a disc/drive unit. The disc/drive unit includes first and second pluralities of discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned in front of the first discs is a ground-engaging driver rotatably coupled to the frame for rotating as the driver engages and is moved across the ground along the direction of travel. A driven flow controller is rotatably coupled and situated between the plurality of first discs and the plurality of second discs. The ground-engaging driver is operatively controlling and preferably accelerating the rotational speed of the driven flow controller.

An apparatus for preparing soil for the placement therein of at least one of seed and fertilizer.
