Abstract: In one aspect, a method for controlling a continuously variable transmission when transitioning the transmission from operation within a hydrostatic mode to operation within a hydro-mechanical mode may generally include initially operating the transmission in the hydrostatic mode, receiving a mode switch signal associated with transitioning the operation of the transmission to the hydro-mechanical mode and initiating a clutch swap between a secondary range clutch and a directional clutch of the transmission. In addition, the method may include adjusting a swash plate angle of the transmission as the directional clutch is slipped in order to transition the operation of the transmission to a point along a hydro-mechanical operating curve and fully engaging the directional clutch to allow operation of the transmission along the hydro-mechanical operating curve.

Abstract: In one aspect, a computer-implemented method for enhancing the performance of a continuously variable transmission of a work vehicle may include engaging a range clutch of the continuously variable transmission, cycling a directional clutch of the continuously variable transmission between an engaged state and a disengaged state while the range clutch is engaged and controlling a position of a swash plate of the continuously variable transmission such that a ground speed of the work vehicle is maintained substantially at zero while the directional clutch is cycled between the engaged and disengaged states.

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: An automatic guidance system for an agricultural vehicle includes a tractor, a towed implement, an absolute tractor position sensor, a relative implement position sensor, and an electronic control system. The operator inputs the implement geometry and field information into the control system. The control system combines this data with the absolute vehicle position and relative implement position to accurately guide the towed implement through a field.

Abstract: A work vehicle has a transmission controller that is configured to determine the direction of travel of the vehicle based upon the state of the transmission. The transmission controller is also configured to communicate this information to navigation system to assist the navigation system in determining the vehicle's movement. The transmission controller determines the direction of travel based upon looking at the clutch state and the vehicle speed.

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 skid steer vehicle has a chassis with four drive wheels suspended from the chassis that are damped by four damping cylinders. An electronic controller varies the damping of the cylinders in an automatic mode, based on certain operational parameters of the vehicle, and in a manual mode in response to operator selection of a desired degree of suspension damping.

Abstract: An access control system for work vehicles has a display, an operator input device and a computer configured to program individual vehicles keys to operate individual vehicles or groups of vehicles.

Abstract: A connector assembly is provided, including a first connector body, and a rotating coupler rotatably secured to the first connector body having at least two securing members. A second connector body is also included, having at least two partially helical securing grooves formed about circumferential portions of an outer surface of the second connector body. Each of the helical securing grooves has an entry end and a terminal end. Upon assembly, the securing members enter an entry end of a respective securing groove and engage an upper axial surface thereof as the rotating coupler is rotated, and each securing member travels along the upper axial surfaces of the securing grooves toward the terminal ends thereof to securely couple the first and the second connector bodies to one another.

Abstract: An array of coaxial cable connectors includes a generally cylindrical-shaped first female member with an inner surface having at least one set of left-hand threads adapted to engage complementary threads on a first male port. A generally cylindrical-shaped second female member has an inner surface including at least one set of right-hand threads adapted to engage complementary threads on a second male port. A mounting member allows for rotation of each of the first and second female members about their respective longitudinal axes while maintaining a portion of the outer surface of the first female member (preferably configured as a gear) in contact with a portion of the outer surface of the second female member (preferably configured as a complementary gear). In operation, rotation of the first female member about its longitudinal axis results in a corresponding rotation of the second female member about its longitudinal axis.
