摘要： 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 the longitudinal centerline forwardly of the first generally vertical pivot axis, is journaled for rotation about a second generally vertical pivot axis. A unique control system effects rotational movement of the gearbox in concert with the pivotal movement of the tongue to maintain appropriate alignment between the tongue and the gearbox.

摘要： A guide link mechanism is supported from the draft tongue of a pull-type harvester and connected to the gearbox mounted on the crop harvesting header to provide rotational power thereto wherein the guide link is supported from a sliding mechanism mounted on the tongue that accommodates the changes in distance in respective points associated with the pivotal movement of the draft tongue about a different pivot center than the gearbox. The sliding mechanism includes a bracket affixed to the underside of the draft tongue and low friction inserts, such as nylon, phenolic, urethane or polyethylene inserts, carried by the bracket. The guide link is connected to a slider plate that is slidably received by the phenolic inserts to permit a sliding movement thereof relative to the draft tongue. The rearward end of the guide link is pivotally connected to the gearbox to accommodate vertical movements of the crop harvesting header relative to the draft tongue. The guide link mechanism effects pivotal movement of the gearbox in response to the pivotal movement of the draft tongue to minimize angular deflection of the universal joints in the drive line supported on the draft tongue to deliver rotational power to the gearbox.

摘要： 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.

摘要： A 4-wheel tractor having brakes on the rear wheels only and an FWD clutch for selectively drivingly coupling the front wheels to the rear wheels, is provided with a control circuit, operative during rear wheel braking, for controlling the clutch so that the front wheels are intermittently coupled to and uncoupled from the rear wheels. Brake pedals which individually control the rear wheel brakes, and a hand brake all control switches connected to a controller. An FWD switch is also connected to the controller. A ground speed sensor applies to the controller a signal representing the speed of the tractor. If the tractor speed is above 15 mph at the time both brake pedals are depressed, the controller selectively controls a solenoid so that the clutch is selectively engaged and disengaged in a first sequence if the FWD switch is ON but selectively controls the solenoid so that the clutch is selectively engaged and disengaged in a second sequence if the FWD switch is in an OFF or an AUTO position. Operation of the clutch effects intermittent front wheel braking as the rear wheels are braked so that front wheel skidding is reduced during hard braking.

摘要： The feed material handling apparatus has a frame supporting a feed-receiving hopper disposed horizontally on said frame and an impeller rotatable about a vertical axis therein impels said material through a discharge tunnel to a substantially vertical blower having an impeller operable about a horizontal axis which urges the material up a vertical transition member into a silo or the like. The hopper adjacent said tunnel is partially covered and provided with air inlet openings, while the sidewalls of said blower are imperforate except for a material inlet opening from said tunnel and openings for a shaft for said impeller of said blower. A metering blade also is mounted adjacent the inlet to said tunnel to control the flow of material to said tunnel.

摘要： A crop harvesting implement has a wheeled frame, a draft tongue pivotable between extreme left and right operating positions, a mechanism for pivoting the tongue, a drive line for transmitting rotational power from a tractor when coupled thereto, a crop harvesting header suspended from the frame and having operable components for engaging and processing crop material, a gearbox for receiving rotational power from the drive line and transmitting the power to the operable components of the crop harvesting header, an input shaft operatively connected to the drive line, a device for mounting the gearbox on the header so that the header rotates, and a steering mechanism for effecting rotational movement of the gearbox in concert with the pivotal movement of the tongue. The steering mechanism is located on the drive line to pivot the gearbox about its generally vertical pivot axis in response to the pivotal movement of the tongue during field operations so as to keep the input shaft of the gearbox at least generally aligned with the tongue.

摘要： A crop conveying drum for a drive disc cutter is mounted directly to the drive shaft mechanism providing rotational power to the cutterbar. The crop conveying drum is formed as mating segments, each forming a half of the drum. Each segment has a pair of support bars vertically oriented and extending between connecting flanges. A mounting bracket centrally supported by the vertical support bars is formed to partially wrap around the drive shaft mechanism. The mounting bracket has holes therein for the passage of fasteners to connect the drum segment directly to the drive shaft mechanism so that the crop conveying drum rotates with the drive shaft mechanism. Upper and lower mating connecting flanges are fastened together to form the entire crop conveying drum rotatable with the drive shaft. The crop conveying drum assists in conveying severed crop material laterally from outlying disc cutters that define a cutting width of the cutterbar that is greater than the operating width of the conditioning rolls. The crop conveying drum is formed in an open configuration to allow the passage of severed crop through the drum so that severed crop cannot accumulate on the drive shaft mechanism to cause an unbalance therein and premature failure of the universal joints due to the wrapping of crop material.
