摘要： In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system acts to calibrate” the control output so that the control module has a secondary reference point as to how the PWM valve should function in the event of a speed sensor failure. Instead of using the speed sensor signal as a reference, the control system now compares the set point with the stored table (which may in one example provide 256 values) containing the PWM voltage/current values. These values correspond to a set of actual speed sensor values taken during the profiling procedure, plus extrapolated values equalling 256 points.

摘要： In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system can be used in an automatic mode to set an index value for an actual difference in reel speed relative to ground speed and to vary reel speed accordingly. In this mode a manually operable control varies the index. The control system can be switched by the operator to manual in which case the same control varies the actual reel speed. Minimum reel speed can be set by the same control and when operative the automatic system does not allow reel speed to fall below the minimum set value despite the values of index and ground speed. A crop-lodged switch is also provided which when operated acts to move the header to a lowered position and the move the reel to a forward most and lowermost position in a single operation controlled by the single switch.

摘要： A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driver's console is rotated in the cab with the steering and speed control elements moved with the seat for the driver to face forwards and its position is detected by switches. In the engine forward position for transportation, the control system detects the seat position and operates the controls for higher speed drive and to prevent operation of the header. The engine has a series of ratings which can be selected depending upon whether the header motor is engaged so that a highest engine speed is used only when the header is disengaged and the lower speed is used for higher fuel efficiency when the header is operating.

摘要： An agricultural tractor having its engine longitudinally spaced along its frame from the operator cabin features at least two heat exchangers carried on the frame at a position located longitudinally between the operator cabin and the engine to perform air-cooling of at least one fluid associated with the engine. The two heat exchangers are arranged in parallel so as to each accept an intake stream of ambient air that is independent of a discharge stream of exhaust air from the other heat exchanger. Accordingly, each heat exchanger uses the coolest air possible to maximize the cooling potential of the system. The discharge stream of air from the heat exchangers is exhausted rearward to avoid recirculation of this heated air as the machine moves forward, and to direct the exhaust air past the engine for further cooling effect.

摘要： A crop harvesting machine including a header mounted on a tractor is hydraulically driven by a pair of pumps on the tractor and a series of motors on the header. A first circuit control includes variable rate valves controlling the rate of supply of fluid from the unidirectional pumps to the motors to vary rate of the knife, conditioner, reel and converging systems in a forward harvesting direction. A second circuit controls reverse rotation of at least some of the elements for releasing a blockage by taking the fluid from one of the pumps and passing it through the separate second circuit to the required motors in series. The second circuit is provided in a separate block which can be omitted and thus constitutes an option. The drive of the motors in reverse direction in series ensures that they are driven at common speed without need from individual speed control. The use of unidirectional pumps and the separate circuits for forward and reverse allows the use of a single return and a filter at the return which is advantageous in a system which allows disconnection of couplings to allow the header to be replaced.
