  • Patent number: 4009556
    Abstract: A crop harvesting vehicle including a self-propelled chassis and a crop harvesting header coupled on the chassis. The header includes a variety of crop handling elements such as a cutter, a reel, a crop-consolidating conveyor, and conditioning rolls which cooperate in a hay windrowing operation. The chassis includes drive wheels driveable from an engine on the chassis through a hydrostatic drive system including two pumps and two motors hydraulically interconnected. The crop handling elements on the header are drivable through a third pump hydraulically connected to a motor on the header. The three pumps are mounted on the chassis with the rotary input drives thereof successively interconnected in coaxial alignment enabling the pumps to be simultaneously driven through a direct common input from the vehicle engine.

  • Patent number: 4002217
    Abstract: The addition of an air diverter to a tractor which has a partially enclosed engine, a shroud in arrangement for supplying cooling air to the engine and a carburetor operatively connected to the engine and mounted within the enclosure. The diverter separates a small portion of the cooling air from the main flow over the engine and uses this smaller flow to maintain an operable temperature for the carburetor.

  • Patent number: 3999674
    Abstract: A machine adapted to be towed by a tractor and powered by the PTO and hydraulic power system of the tractor for loading, transporting, shredding and feeding a module (bale or stack) of hay of substantial size and weight. The machine includes a frame and a load bed thereon. The frame mechanically supported on a pair of ground wheels which are swingable relative to the frame to tilt the load bed rearwardly into ground engagement. A module pickup ramp or fork is pivotally mounted on the load bed for lifting a module onto the load bed. A conveyor on the load bed moves the module forwardly against a plurality of vertically spaced rotary shredders. The shredded hay falls upon an auger conveyor which feeds the hay from the machine into a feed bunk or onto the ground for livestock feeding.

  • Patent number: 3994133
    Abstract: In a hydraulic power system having two independent circuits, wherein one circuit has priority over the other circuit, and the priority circuit furnishes a residual flow to the non-priority circuit, a pressure sensing system is provided in the return flow line of the non-priority circuit which causes a directional flow valve to shift and direct the residual flow back to the priority circuit in the event of a leak in the non-priority circuit which results in a loss of pressure in the return line.

  • Patent number: 3991735
    Abstract: An internal combustion engine, which has soundproofing cowling, uses the space between the sidewalls of the cylinder block and the cowling to provide a reservoir for a liquid lubricant media. A cover cap is provided over the fuel injection and valve timing mechanisms, and the space between the cover cap and the cowling, which is over the top of the cylinder head, provides a chamber for receiving coolant from the engine cooling system. The large surface area of the cowling along the sides of the cylinder block accommodates the transfer of heat from the lubricant to the atmosphere. In addition both the lubricant and the coolant serve as sound deadening medias in the sidewall reservoirs and in the overhead chamber.

  • Patent number: 3990504
    Abstract: The invention disclosed in this application relates to an improvement in a water cooling system for an engine of the type that passes air and water through the radiator at relatively low flow rates whenever the engine is running in its low idle speed condition. The radiator is disclosed as having upper and lower headers interconnected by a plurality of parallel extending rows of water tubes. A means responsive to the engine speed is provided for converting the water flow through the water tubes from a plurality of parallel paths to a single series path upon the engine speed dropping to its low idle speed condition.

  • Patent number: 3988977
    Abstract: A hay baler for picking up windrowed hay, forming a cylindrical bale, feeding twine onto the bale during the latter stage of bale formation, and cutting the twine after the bale is wrapped. The hay is picked up and fed rearwardly under a press roller onto an endless belt. A plurality of oppositely running belts is disposed above the lower belt defining a bale-forming zone there-between. The twine extends from a source of supply on the baler through an elongated twine feed tube. The tube is pivotally mounted such that its dispensing end is swingable through an arc above the incoming hay to and from a home position for feeding twine into the hay and around the bale. As the tube is swung back toward the home position a twine hook is actuated through an interconnected linkage and the twine is pulled downwardly onto a fixed knife which severs the twine.

  • Patent number: 3985472
    Abstract: A hydraulic pump arrangement and control circuit for supplying fluid at high volume and a high pressure to a work circuit. The system utilizes a fixed displacement pump, a variable displacement pump, a dual pressure compensator, and an unloading valve working together to provide high pressure fluid delivery while reducing the horsepower requirements of the fixed displacement pump and the variable displacement pump. High flow is provided through the utilization of the combined pumps and high pressure is attained through the unloading of the fixed displacement pump through the unloading valve and destroking of the variable displacement pump in response to signals provided by the dual pressure compensator.

  • Patent number: 3985196
    Abstract: A safety start system for lawn and garden equipment in which a single safety switch completes the starting circuit of the power source by responding to the disengaged condition of both the main clutch and the implement clutch of the machine. The starting circuit is completed in direct response to the operator's moving the implement clutch handle to its disengaged position thereby permitting a resilient actuating member to close a safety switch and complete the circuit. The circuit is interrupted upon his engagement of the main clutch through a release of the clutch pedal which changes the deflection point of the resilient actuating member from the safety switch to linkage which is connected to the clutch pedal mechanism.
