Abstract: A mower deck can include a linkage that enables adjusting the height of the mower deck with a single action. The mower deck can include a rolling mechanism support arm at each corner and a coupling mechanism that extends between the front and rear rolling mechanism support arms on each side of the mower deck. A shaft can extend between the two front rolling mechanism support arms and can be rotated via an actuator. When the shaft is rotated, the front rolling mechanism support arms will rotate in unison, and the coupling mechanisms will cause the rear rolling mechanism support arms to also rotate in unison. In this way, a single action can cause the height of the mower deck to be adjusted.

Each of the rotatable threshers is attached to the central rotatable mount and in line with a stationary thresher. A plurality of cutters is attached to the outer shell, a flame source projects a flame into the drum, and a water source projects water into the drum. The cut crop passes into the cut crop opening, to be further cut by the plurality of cutters and threshed by the plurality of rotatable threshers, such that the flame and water are projected onto the cut crop, resulting in a processed crop and detritus that is separated from the processed crop.

Abstract: An apparatus for automating the process of bunching straw in a farming operation is disclosed. The straw buncher is a towable implement that includes one or more rakes mounted on a rotatable axle. The rakes gather straw. Rotation of the rake assembly is prevented by a stop mechanism that holds a rake in position using a resistive force until sufficient straw has gathered in front of the rake and the drag created by the straw overcomes the resistive force. At this point the rake begins to rotate, a cam on the rake assembly engages a drive system that turns the rake assembly until the next rake is in position. The implement works automatically and does not require monitoring by an operator to have straw bunches of a desired size be formed.

Abstract: A self-adaptive throwing device for stalks cutting and discharging in the longitudinal axial flow combine harvesters comprises a longitudinal axial flow stalk discharging and guiding device, a stalks remnant shredding device, a wind direction and wind speed detection device, a reaping region identification device, an operating speed sensor, a shredding revolution speed sensor, a width adjustable throwing device, a self-adaptive throwing real-time control system. The throwing width is self-adaptive based on the machine operating speed, wind speed, wind direction, the position of the region having been cut and the region waiting to be cut, so as to achieve the full width throwing of the stalks remnant. An arc stalk guiding plate and a flow separating bar are mounted in the longitudinal axial flow stalk guiding device to make the shredding load more even.

Abstract: A mower deck dual wedge system uses a dual wedge configuration to funnel vine like material for cutting to prevent interference with a spindle shaft. The system includes a mower deck having an upper wall and a peripheral. A spindle shaft extends through the upper wall. Each of a pair of wedges is coupled to and extends from the upper wall of the mower deck. Each of the wedges has a pair of lateral sides extending from a tip.

Abstract: An improved crushing tool for the processing of aggregates, and a heat treatment method for metals used in the fabrication of such tools, is provided. The crushing tool may comprise an attachment portion having a relatively low material hardness and a crushing portion having, in comparison to the attachment portion, a relatively high material hardness. For example, the hardness of the attachment portion may be in the range of 20-35 HRC, and that of the crushing portion may be in the range of 50-60 HRC. Use of tool-grade steel, such as AISI S7 steel, may thereby result in a tool offering a compromise between the hardness (wear-resistance) of the crushing portion and the toughness of the attachment portion. A heat treatment process for the tool-grade steel may involve distinct heating, quenching, and tempering cycles in order to achievable desirable material properties.
