Abstract: An agricultural vehicle having a hydraulic system, a cab for the vehicle operator includes a self-levelling cab suspension system having a plurality of suspension units each having a spring, a damper and an accumulator. The accumulator comprises a hydraulic working chamber which is separated by a movable wall from a gas filled chamber serving as a spring. The working chamber is also connected to a working chamber of the damper in a closed hydraulic circuit. In the invention, there is no need for a dedicated oil pump since a hydraulic actuator powered by the vehicle hydraulic system is provided for causing hydraulic fluid to flow in the closed hydraulic circuit between the working chamber of the accumulator and the damper, to vary the height of the cab without fluid from the vehicle hydraulic system entering or leaving the closed hydraulic circuit of the damper and accumulator.

Abstract: A trailer braking device having a high-pressure main hydraulic circuit of a tractor to which a trailer is attached; to a hydraulic circuit of a master brake cylinder of the tractor; and a trailer brake valve having a driver connected hydraulically to the high-pressure main hydraulic circuit and to the hydraulic circuit. The driver of the device has a piston which is subjected to a first action by an independent circuit that is activated, for example, by the stop lights and a second action produced by the operator, such as a foot acting on a brake pedal, on the hydraulic circuit of the master brake cylinder.

Abstract: An independent suspension for a rear wheel of an agricultural vehicle includes upper and lower longitudinal trailing members that are each secured at a chassis location for pivoting movement about respective upper and lower, horizontally extending axes. A planetary gear mount is secured between the trailing members at upper and lower attachments that are spaced from the chassis ends of the trailing members; and a spring attachment protrudes from the planetary gear mount.

Abstract: An agricultural vehicle and method of operating the same, where the agricultural vehicle has an engine, a continuously variable transmission, a processor, an inching controller, and a speed controller. The speed controller sends a first signal to the processor, and the processor controls the transmission to operate the vehicle at a first speed based on the first signal. The inching controller sends a second signal to the processor, and the processor controls the transmission to move the agricultural vehicle in a forward or reverse direction, depending on the second signal. If the first speed based on the first signal is zero, the second signal triggers the processor to control the transmission to move the agricultural vehicle in the forward or reverse direction a predetermined first distance. The control of the vehicle to be at zero speed or to be in a particular position is effectuated by a position control mechanism.

Abstract: A continuously variable transmission can have one or more rotatable output shafts, rotatable non-output shafts, continuously variable transmission elements selectively interconnecting at least one non-output shaft and one output shaft so as to permit variation of a transmission ratio therebetween. The transmission can also have one or more control elements for controlling the instantaneously prevailing ratio of the transmission including a sensor device for sensing the rotational position of a non-output shaft, and a processing device for determining the rotational position of the sensed, non-output shaft at a chosen instant. The processing device is connected to control elements to cause variation of the transmission ratio so that the output shaft attains a desired rotational position at a chosen instant.

Abstract: A method and a jig for mounting of a stack of Belleville springs about a shaft. The individual springs of the stack are first positioned over the shaft. A jig is then placed over the shaft and the springs and has at least one axially extending pressure bar that is radially inwardly biased to urge the inner circumferences of all the springs into contact with axially aligned points on the surface of the shaft. The springs are then compressed using a compression element while they are still urged by the pressure bar against the shaft. Finally, to retain the springs on the shaft and maintain the springs in compression, a split retaining clip is pressed onto to the shaft until it engages in a groove.

Abstract: A power take-off device for an agricultural vehicle, in particular a tractor, wherein an input shaft is connected to a first and, selectively, a second output shaft by moving a sleeve-type selector between three selection positions, in the first of which, the input shaft is connected angularly to the first output shaft to rotate the first output shaft at a first speed, and in the second and third of which, the input shaft is connected angularly to the second output shaft to rotate the second output shaft at a second speed and a third speed, different from the second speed.

Abstract: A method and device for longitudinally balancing an agricultural vehicle, in particular a tractor, whereby at least one sensor, for detecting at least one respective stress affecting a longitudinal attitude of the agricultural vehicle, controls an actuating device of a ballast to move the ballast longitudinally along the agricultural vehicle, which at least partly compensates for the stress.

Abstract: A system and method for managing an engine-powered vehicle is provided. When the vehicle is placed in an automatic speed control mode, an electronic controller receives data from the vehicle's engine, transmission, a final drive, and a device which evaluates at least one variable. The electronic controller determines engine rpm and transmission gear as a result of the data received, and automatically up-shifts the transmission and reduces engine speed to reduce fuel consumption when a load on the vehicle is reduced and down-shifts the transmission and increases engine speed when a load is applied.

Abstract: A steering and engine speed control mechanism for operating a vehicle. The control mechanism has a control handle mounted on the vehicle. The control handle is configured to deflect about an axis by movement of an operator's hand. A steering direction of the vehicle is related to a deflection angle of the control handle about the axis. An actuating element for changing the speed of the engine of the vehicle is attached to the control handle and is conveniently movable by an operator's digit to a plurality of positions to effect the desired speed of the engine.

Abstract: An apparatus and method for generating swath lines including compensation for sloping terrain in a field for use in an automatic guidance system of a work machine. The swath lines are created as a function of the position, elevation and/or orientation of the work vehicle.
