摘要： A vehicle transmission system having shift levers mechanically linked to couplers for selection of ranges of gear speed ratios and electro-hydraulic powershift clutches for selection of a gear speed ratio within the selected range is provided with controls for avoiding unexpected speeds or speed changes under certain conditions. If the vehicle is moving at start-up as a result of a stall or accidental reset of the microprocessor, and the shift levers have not been moved since the stall or reset, the microprocessor retrieves from a nonvolatile memory an indication of the last selected powershift gear prior to the reset and uses it for the initial powershift gear selection. When an operator depresses a clutch, shifts a shift lever and then changes his mind and shifts the shift lever back to its original position before releasing the clutch above a threshold point, the microprocessor selects the powershift gear in effect at the time the clutch pedal was depressed.

摘要： A loader having hydraulically operated boom and bucket mechanisms controllable from the operator seat is disclosed wherein switches sense the presence of the operator in the seat and the buckling of the seat belt. An electronic controller is operably associated with the seat and belt switches and solenoid valves in the hydraulic system and the starter relay. The controller requires proper sequencing of the activation of the seat and belt switches before permitting the starter to be energized, thereby controlling the starting of the loader engine, or permitting the energizing of the hydraulic solenoid valves to control the flow of hydraulic fluid to the hydraulic cylinders for the boom and bucket. The controller also includes a delay associated with the seat switch so that a reactivation of the seat switch within the delayed period of time would allow the hydraulic system to operate without requiring a resequencing of the activation of the seat and belt switches.

摘要： In a rectangular baler wherein a plunger is reciprocated by connecting rods to force crop material through a bale casing, and a microprocessor-based control circuit monitors the stress in the connecting rods to develop a digital value representing the pressure which should be applied to the tension rails of the casing in order to obtain baled crop material of desired density, the digital value is compared with upper and lower limits of the pressure which may be applied to the tension rails. If the digital vaue falls below the lower limit or exceeds the upper limit a visual indication of the condition is displayed for the operator.

摘要： In a forage harvester having a metal detector with permanent magnets located within a crop feed roll, additional permanent magnets are positioned beyond the ends of the feed roll and at a distance greater than the radius of the feed roll from the axis of rotation of the feed roll. The additional magnets cooperate with magnets within the feed roll to provide a more uniform flux density across the width of the feed roll, even in regions near ferrous side sheets defining the lateral limits of the harvester feed path. Tramp metal is thus detected with equal facility regardless of its trajectory past the feed roll.

摘要： In a rectangular baler wherein right and left conrod load cells measure the force applied to plungers for compacting crop material, a microprocessor based control circuit monitors the loads registered by the load cells. The microprocessor produces output signals to control the baler in accordance with the loads sensed by the cells. On a stroke of the plunger, a one-quarter second interval is tolled after one cell registers a load. If the second cell does not register a load within the interval it is assumed that it is faulty. In order to permit continued operation of the baler, the output of the good cell is assumed to be, and is used by the microprocessor as if it were the output of the faulty cell.

摘要： An agricultural baling machine controls the density of bales of crop material discharged therefrom by monitoring the stress experienced by a reciprocably driven plunger assembly (22) employed to apply a compactive force to crop material introduced into a bale case (20). The bale case (20) is comprised of rails (54, 56) which are positionably adjustable in response to applied tension in a manner whereby the dimensions of the bale case (20) are changeable, thereby facilitating a change in the degree of resistance caused by the bale case (20) to crop material movement therein. Signals produced by stress sensors (124, 126, 128, 130) mounted relative to the plunger assembly (22) are analyzed by a programmed signal processor (200) which accordingly generates a control signal for controlling a servo valve (61). In response to the control signal the servo valve (61) governs the degree of tension applied to the bale case raisl (54, 56) and thereby adjusts the degree of resistance to crop movement in the bale case (20). The analysis performed by the signal processor (200) results in the generation of a pulse width modulated control signal that enables the servo valve (61) to adjust the degree of resistance to crop movement in the bale case (20) so that the stress experienced by the plunger assembly (22) is maintained near a predetermined level in accordance with desired bale density.

摘要： An automatic baling machine for forming round bales and wrapping them with twine is provided with a microprocessor-controlled signal processing circuit for controlling movement of a bidirectional motor which drives a pair of twine tubes. Retract/extend switches are manually actuated by an operator to store in the signal processing circuit a sequence of control words which are subsequently executed to control movement of the twine tube drive motor. In addition to being connected to the input of the signal processing system, the retract/extend switch are connected in parallel with the signal processing circuit to actuate the twine tube motor.
