Abstract: A front suspension for a tractor has an axle that is pivotally coupled to an axle carrier to pivot about a substantially longitudinal axis. The axle carrier, in turn, is pivotally coupled to the chassis of the vehicle to pivot about a generally vertical axis. The front end of the axle carrier is supported by a counter frame that prevents the axle carrier from twisting about a longitudinal axis. The counter frame is pivotally coupled to the chassis of the tractor to pivot about a generally lateral and horizontal axis. Both the axle carrier and the counter frame are constrained to pivot about the common horizontal and lateral axis with respect to the chassis of the tractor. Springs are coupled between the counter frame and the chassis of the tractor to control the pivoting of the counter frame with respect to the tractor and provide shock absorbing for the front suspension.

Abstract: The apparatus is an automatic velocity control system for an agricultural machine. Three feedback circuits are used to increase reliability and repeatability of the apparatus despite variations in load and ground conditions and non-linear responses of control components. A solenoid current sensor supplies a feedback signal to control a current controller for solenoids controlling a hydraulic valve, a hydraulic cylinder position sensor provides a feedback signal to counteract the non-linearity of the hydraulic valve controlling the hydraulic cylinder, and wheel speed sensors supply vehicle speed signals to be compared to the signal from the operator's speed control. A microprocessor processes the sensor signals to maintain the desired velocity.

Abstract: An electronic control system for a machine having a boom assembly and an implement assembly. A microprocessor is provided having an input and generating first and second output signals.

Abstract: A neutral start interlock for a hydrostatic drive system that uses potentiometers to electronically monitor at least the position of the hydrostatic displacement control such that the engine will not start unless such control is in the neutral position.

Abstract: A rotor stripper mount pivotably fixed at its ends to the rotor frame of a round baler for arcuate fore-and-aft movement selectively fixable to the rotor frame. The arcuate fore-and-aft movement alters the distal relationship between the stripper channels and the rotor fingers and surfaces.

Abstract: An operative arm of an earth moving machine includes a dipper stick having a distal end, a bucket coupled to the distal end of the dipper stick, a hydraulic actuator coupled to the dipper stick, and a linkage generally interposed between the bucket and the hydraulic actuator. The linkage includes the following items: (i) a first lever rotatably coupled to the dipper stick and the hydraulic actuator, (ii) a linear actuator rotatably coupled to the dipper stick, (iii) a second lever rotatably coupled to the first lever and the linear actuator, and (iv) a bucket lever interconnecting the second lever, the linear actuator and the bucket.

Abstract: A dozer blade control system controls the position of a bulldozer blade, maintaining the blade at a constant position as the dozer travels through a worksite. The control system monitors the angle of the dozer blade with respect to the earth and when it senses that the dozer blade is tilting, it corrects the dozer blade's position by extending or retracting hydraulic cylinders that couple the dozer blade to the chassis of the crawler-tractor. When the dozer chassis pitches forwards, the blade begins to tilt forward and to drop closer to the ground. The control system senses this forward rotation of the blade and retracts the hydraulic cylinders that couple the blade to the chassis, causing the blade to return to and maintain its original position.

Abstract: A system for automatically moving a stabilizer of a work vehicle is disclosed. A joystick is connected to an electronic controller, which in turn, is connected to valve drivers to drive stabilizer raising and lowering valves. In one mode of operation, the controller is programmed to move the stabilizers up or down at a rate that is proportional to the deflection of the joystick from a neutral position. If the operator holds the joystick in a certain position or range of positions, the controller enters a second mode in which it automatically raises the stabilizers even if the joystick is released. The stabilizer can be placed in a third mode of operation by moving the joystick rapidly back and forth. When the operator does this, the controller is configured to reduce the ramp rate or damping of its response to joystick movement.

Abstract: A wheeled vehicle including a chassis; an axle coupled to the chassis to oscillate about a longitudinal axis parallel to a direction of advance of the vehicle; a pair of cylinders disposed between the axle and the chassis for blocking oscillation of the axle; and a fixing assembly for fixing the cylinders to the chassis, the fixing assembly comprising a plate, a plurality of connection screws extending through the plate, at least one annular rest portion affixed in cantilever fashion to one of the chassis and the plate, the annular rest portion surrounding a corresponding one of the plurality of connection screws and defining a shoulder that supports the plate in a radial direction with respect to the axis of the connection screw.

Abstract: A wet clutch includes a clutch carrier that encloses a stack of clutch plates and a clutch backing plate. Two sets of alternating slots are provided in the clutch carrier. One set of slots is shallower than the other set and is configured to support the clutch backing plate. The other set of slots is deeper and is configure to support many of the clutch plates. The first set of slots is shallower in order to keep the clutch backing plate from pressing against and partially binding the stack of clutch plates together.

Abstract: A parking brake for a motor vehicle includes: a manual operating lever; a braking device designed to act on brake disks applied on a bevel pinion for transmission of the motion to the wheels of the motor vehicle; and a cable for transmission of the command imposed via the lever on the braking device. The brake is activated either automatically by a hydraulic actuator when the engine of the motor vehicle is turned off, or alternatively, by a manual command imposed by the operator through the lever whether or not the engine of the motor vehicle is running.

Abstract: An earthmoving vehicle has an operating arm that is raised and lowered by a hydraulic system. The hydraulic system includes a drain line and at least one actuator connected to the operating arm. The actuator defines a variable-volume chamber connectable to the drain line to lower the operating arm. The hydraulic fluid discharged from the chamber flows through a proportional safety valve adjacent to the actuator and a distributor valve that is driven by a pilot control valve to allow free flow to the drain line. Thus, the lowering of the operating arm is controlled solely by the proportional safety valve.
