Abstract: The device consists of a two stage hydraulic tongue swing mechanism and a tongue latch mechanism for controlling and affixing the tongue of a pull type implement while the implement is being laterally transported. The two stage hydraulic tongue swing mechanism comprises a tongue plate attached to the tongue. A free plate is pivotally attached at the tongue pivot and is controlled by a hydraulic cylinder. The tongue plate and free plate are selectively attached to each other by a lateral transport latch. The tongue latch mechanism is partly affixed to the tongue and partly to the trailframe. Attached to the tongue is a tongue handle that controls the position of a tongue pin. The tongue pin is biased into an angled strike plate with a slot on the edge of the trailframe. The tongue pin may be held in a retracted position by a notched lock bar.

Abstract: A feederhouse on an agricultural combine. Having a first acoustic array having a first sounding board and acoustic sensor positioned beneath the front drum and feederhouse floor. A second acoustic array positioned behind the front drum and between the conveyor chain encircling the front and rear drums. The second acoustic array also has a second acoustic sensor and second sounding plate. The acoustic sensor detects the impact of a stone on the sounding plates. A signal is transmitted via a controller from the sensor to a solenoid controlling a stone trap door latch. When the door opens, a sled also rotates into contact with conveyor chain. This deflects any crop flow containing stones. To close the door, the feederhouse is raised and the door rotates into contact with the latch.

Abstract: The invention consists of an offset kingpin in the rear steering axle of a self-propelled combine harvester. Attached to the rear axle is a knuckle. The kingpin is pivotally attached to the knuckle and the spindle is rotationally attached to the knuckle. The kingpin is positioned forward of the spindle allowing the rear tires equal clearance with the combine side shielding. This positioning of the kingpin relative to the spindle improves the turning radius of the combine. It also aids tire stability at road speeds.

Abstract: The invention consists of an engine driving a wet clutch and hydrostatic pump and connected hydrostatic motor. The output of the motor drives the sun gear of a hydro-mechanical planetary drive and the output of the clutch drives the ring gear of the same drive. The carrier is the output and drives the rotors of an agricultural combine. The transmission is controlled by a microcomputer. The microcomputer receives signals from an engine speed sensor and a rotor speed sensor and transmits controlling signals to the hydrostatic pump's swash plate and to a clutch valve allowing a quantity of hydraulic fluid to enter the clutch. The microcomputer can also send a signal to brake the ring gear while reversing the direction of the hydrostatic pump motor to allow act as a reverser for the rotor. The microcomputer also can receive signals from the rotor speed sensor to open the clutch valve allowing a quantity of hydraulic fluid to enter and synchronize the clutch.

Abstract: A rotating bubble-up auger of an agricultural combine harvester having a fixed, lower auger assembly receiving a grain from a clean grain elevator. The rotating upper auger assembly is connected by a roller assembly to the lower auger assembly. A handle controls movement of the upper auger assembly. The operator lifts a spring-biased pin upwards and can rotate the assembly manually. Another option allows for the use of an electric motor that drives a worm gear. The worm gear contacts a series of collar teeth on an upper auger collar positioned on the upper auger assembly.

Abstract: A round baler for forming crop material into cylindrical bales, having a main frame, a plurality of conveying elements supported on main frame for defining a bale forming chamber, and a pickup for feeding crop material into said chamber. The conveying elements each have a crop engaging surface extending transversely of the main frame for forming a cylindrical package of crop material under conditions where the pickup is feeding crop material into the chamber. A dispensing assembly dispenses wrapping material from a storage container into the chamber for wrapping the outer surface of the cylindrical package of crop material to form a round bale. The storage container, mounted in an operative position on the main frame, is pivotable to an inoperative position away from the dispensing assembly for providing unobstructed access to the storage container and the dispensing assembly.

A transverse reel assembly and an auger conveyor are mounted on the main frame for picking up crop material from the ground, consolidating it and conveying it to the forage harvester base unit via the input opening. A ground gauging roller assembly supports the attachment to protect the reel during operation over uneven terrain. The assembly is adjustably mounted relative to the main frame.

Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system.

Abstract: A self propelled windrower having no brake pedal is provided with a signal light system conforming to standards for agricultural equipment traveling on public roads. The ground speed of the equipment is sensed and, after it exceeds a threshold speed, computation of equipment acceleration/deceleration begins. When the deceleration exceeds a deceleration threshold, the brake lamps are enabled according to the settings of left turn and right turn signal switches. The brake lamps are enabled as long as the deceleration exceeds the threshold and for a short interval (2 sec) thereafter. If the speed drops below the speed threshold during the short interval, the brake lamps are enabled for an extended period (2 min).

Abstract: An agricultural harvesting machine having a threshing and separating mechanism for threshing and separating crop material; and cleaning mechanisms for cleaning the threshed and separated crop material. The cleaning mechanism comprising: a grain pan for receiving threshed and separated crop material and transporting the latter rearwardly; and an upper and lower sieves installed behind the grain pan and operable to receive the material from the grain pan and move it through and along. At least one portion of the grain pan is inclined in a sideways direction for sideways movement of the threshed and separated crop material while it is being transported rearwardly towards the sieve. This inclination spreads out the surplus of crop material supplied to one longitudinal section of the grain pan and delivers it in an even pattern to the front section of the upper sieve.

Abstract: A splitter gearbox for a four wheel drive, hydrostatically driven tractor integrates both the input drive train and the output drive train into a single gearbox. The splitter gearbox is mounted to the rear axle housing to allow the sharing of a common oil sump. The front and rear axles of the tractor are driven from a single hydrostatic motor associated with a gear drive system that provides a shaft extending forwardly and rearwardly out of the splitter gearbox to drive, respectively, the front and rear axles of the tractor. An auxiliary pump drive is mounted to the side of the splitter gearbox and driven from an idler gear appropriately positioned within the splitter gearbox.

Abstract: A splitter gearbox for a four wheel drive, hydrostatically driven tractor integrates both the input drive train and the output drive train into a single gearbox. The drive mechanism eliminates the need for a separate mechanical gearbox by establishing pre-set fixed displacement settings that are electronically controlled along with the variable displacement of the hydrostatic motor and hydrostatic pump, to provide a smooth power shift through all ranges without requiring the tractor to stop. The drive mechanism is configured so that essentially all components are individually controlled so that the entire power generated by the tractor engine can be diverted to any one of the traction drive, the PTO mechanism, the auxiliary hydraulic drive or, to a somewhat lesser extent, the tractor hydraulic system. The splitter gearbox is mounted to the rear axle housing to allow the sharing of a common oil sump.

Abstract: A baler (10) for wrapping a rotating bale (52) of crop material (26) with strands of twine (72) has two twine tubes (68) through which the twine is fed so that ends of the strands dangle from the tubes. A bale density sensor (36) senses bale density and a controller (42) compares the sensed density with a desired density selected by an operator via an operator control panel (34). When the sensed density reaches about half the desired density the twine tubes are moved to a twine insert position so that the ends of the strands dangle adjacent the rotating bale. When a full bale has been formed, a duckbill (60) is actuated to push the ends of the strands toward the bale where they are caught up in the crop material. If either strand is not caught up in the rotating bale, the operator may abort the wrap cycle and initiate a new wrap cycle by pressing a wrap key on the control panel.

Abstract: An agricultural vehicle is described having a chassis and a cab mounted on the chassis. The fore end of the cab is mounted on the chassis for pivotal movement about a transverse axis but is prevented from moving relative to the chassis in a vertical plane. The aft end of the cab is resiliently supported on the chassis by springs and is connected to the chassis by means of a linkage, preferably a Watts linkage, that permits movement of the aft end of the cab in a vertical direction towards and away from the chassis while preventing transverse movement of the aft end of the cab.

Abstract: A disc mower conditioner utilizing a modular disc cutterbar to sever standing crop material by impact action. The side sheets of the disc mower conditioner are provided with a rolling crop divider that can be an optional attachment. The rolling crop divider is constructed as a series of overlapping rolling coulters mounted to the side sheet by bearings to enhance the rolling operation of the coulters. The rolling coulters effectively divide the crop material to direct tall and entangled crops into the header to be severed by the rotating knives. The coulters are arranged in a trailing orientation to present a curved leading edge that is highly effective in directing tall, entangled or viney crops downwardly into engagement with the adjacent disc cutter.

Abstract: A crop harvester having a wheeled frame with a tongue pivotally connected to the frame in the vicinity of a longitudinal centerline. The tongue, rotatable about a first generally vertical pivot axis, is swingable between extreme left and right positions on opposing sides of the longitudinal centerline with its distal end adapted for connection to a prime mover. A drive line transmits rotational power from the prime mover. A crop harvesting header, suspended from the frame in a forward disposition, includes operable components for engaging and processing crop material as the harvester is pulled over a field of standing crop. A gearbox receives rotational power from the drive line and transmits it to the operable components. The gearbox, mounted on the crop harvesting header in the vicinity of said longitudinal centerline forwardly of the first generally vertical pivot axis, is journaled for rotation about a second generally vertical pivot axis.
