Abstract: An agricultural combine having a supporting structure that is driven by ground engaging wheels at a harvesting speed by a propulsion assembly. The combine is also provided with a threshing assembly that is driven by a variable torque sensing drive. The variable torque sensing drive is manipulated by pressurized hydraulic fluid. A hydraulic sensor in hydraulic communication with the variable torque sensing drive provides an actual hydraulic pressure signal that is directed to an electronic controller. An operator control in the operator's cab of the combine provides a loss rate signal that is also directed to the electronic controller. The electronic controller converts the loss rate signal into a desired hydraulic pressure signal. The electronic controller regulates the forward speed (harvesting speed) of the combine so that the desired hydraulic pressure signal is equal to the actual pressure signal.

Abstract: A device for adjusting the opening width of vibrating sieves in a cleaning mechanism of combine harvesters is arranged on and vibrates directly with the sieves or the sieve frame. The device includes an electric-motor-driven adjusting mechanism which actuates in a direction along an axis which differs from the direction in which the sieve is vibrating. A detector is activated when a particular sieve opening width is achieved. When the detector is activated, the particular opening width is associated with a position of the adjusting mechanism as measured by a position sensor, thereby allowing calibration of further adjustments to the sieve opening.

Abstract: A lawn mower includes a front wheel suspension system as well as a rear wheel suspension system. The front wheel suspension system includes upper and lower suspension struts that are pivotably connected between a main frame of the lawn mower and a longitudinal suspension strut that is connected to a front wheel. A spring is connected between an extension of the upper suspension strut and a front transverse member of the main frame. The rear wheel suspension system includes upper and lower links that are pivotably connected between vertical struts that are connected between upper and lower frame members of the main frame and a motor mount. A spring is connected between a spring bracket extending from the upper frame member and either the motor mount or a motor mounted in the motor mount. In order to prevent scalping while turning, a floating cutter deck is suspended from the front and rear wheel suspension systems rather than from the main frame or chassis of the mower.

Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff from straw, and returning the straw to the field. This is carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and preferably the harvesting unit and vehicle, are designed to make this possible.

Abstract: A self-propelled crop harvester or one of the train of towing vehicle and towed implement for processing harvested crop are equipped with a measuring device for the measurement of components in and/or properties of harvested crop that is conveyed along a path and/or along which the measuring device is moved. The measuring device is an optical spectroscope which operates in the visible wavelength range and/or in the near infrared wavelength range. Measurements made are used to determine the amount of particular organic components contained in the harvested crop, such as carbohydrates, organic substances that can be dissolved in enzymes, oil and raw protein; and to determine the amount of non-organic components contained in the harvested crop, such as minerals, for example sodium and magnesium or water. Further parameters of the harvested crop are also measured including solid matter and raw fiber content, length of fibers, caloric or energy content, digestibility and color.

Abstract: A harvester includes an integral two-section baling device with the section movement designed to provide both a bale discharge function and a transport height reduction function. In one embodiment, one section of the device includes rollers which follow a downwardly sloped ramp as the sections are opened relative to each other. The sloped ramped additionally serves as a portion of a finished bale handler and bale support. In a second embodiment, an additional hydraulic cylinder system controls the downward movement of the opened sections towards the transport position. Existing baler functions are advantageously utilized to provide transport height reduction with a minimal amount of additional hardware, and the operator can switch between transport and operational modes quickly and easily.

Abstract: An apparatus for attachment to a rear end of a combine for spreading straw and chaff comprises a pair of side-by-side rotating pans with attached blades for spreading chaff, with a straw spreader attached to and above each pan to spread straw before same falls onto the pans. Each pan is enclosed at the front by a vertical wall with an opening to allow chaff to exit to the rear and side. A lip extends from the top of the wall toward the center of the pan to enhance the air blast and increase the distance chaff is blown. Rear deflectors allow the amount of chaff directed to the rear to be varied.

Abstract: The combine of the present invention is provided with an internal combustion engine. An electronic engine controller is used to monitor and control the operation of the engine. The electronic engine controller stores at least two power curves for controlling the engine. The first power curve has a higher horsepower output than the second power curve. A harvesting assembly detector signals the electronic engine controller with a corn head signal if a corn head is mounted to the combine, or a grain platform signal if a grain platform is mounted to the combine. If a corn head is mounted to the combine the electronic engine controller derates the engine and works on the second power curve. If the electronic engine controller receives a grain platform signal, the electronic engine controller works on the higher horsepower first power curve.

Abstract: A mower comprises a frame having a cutting deck which is tiltable relative to the frame. The cutting deck has a substantially horizontal operating position and a generally upright transport or service position, the cutting deck tilting to move between the horizontal and upright positions. A blower is carried on the frame and a plenum connects the blower and the cutting deck. A grass discharge outlet on the cutting deck is telescopically inserted into the front of the plenum as the cutting deck is moved into its operating position. A guide pin is received in a slot having a V-shaped portion and a straight portion to correct misalignment between the cutting deck and the plenum as the two are telescoped together. The rear of the plenum can be manually attached to or released from the blower inlet without using tools.

Abstract: The invention is a grain tank which pivots about an axis transverse to the direction of travel to facilitate grain flow to the unloading system. The grain tank is sloped and curved to allow the grain to be easily and completely discharged from the tank. Grain is delivered from the clean grain system to a first auger which transports the grain to either a second auger or bubble up auger. The grain can enter the grain tank by the bubble up auger or may be discharged to the unloading system via a second auger. While unloading, the tank pivots from its lowest position to its highest position, only as needed, to maximize output.
