A vehicle steering assembly for controlling movement of a vehicle having independently rotatable left and right ground-engaging traction elements. The steering assembly comprises a steering handle coupled to the panel support structure and extending generally upwardly from the panel support structure. The steering handle comprises a laterally-extending crossmember and at least one upright extension member. The crossmember and the upright extension member are rigidly connected to one another so that shifting of the crossmember relative to the extension member is substantially prevented. The steering handle is shiftable in forward and rearward directions to thereby cause corresponding forward and rearward rotation of both of the left and right traction elements. The steering handle is rotatable in clockwise and counterclockwise directions to thereby cause a change in the relative speeds and directions of rotation of the left and right traction elements.

In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick, and a joystick position sensor. The MRF joystick resistance mechanism is controllable to selectively resist movement of the joystick relative to the base housing. The controller architecture is configured to: (i) when detecting operator rotation of the joystick in an operator input direction, determine whether continued joystick rotation in the operator input direction will misposition the work vehicle in a manner increasing at least one of work vehicle instability and a likelihood of work vehicle collision; and (ii) when determining that continued joystick rotation will misposition the work vehicle, command the MRF joystick resistance mechanism to generate an MRF resistance force deterring continued joystick rotation in the operator input direction.

Embodiments of a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device having a base housing, a joystick movably mounted to the base housing, and a joystick position sensor monitoring movement of the joystick relative to the base housing. An MRF joystick resistance mechanism is controllable to vary a joystick stiffness resisting movement of the joystick relative to the base housing in at least one degree of freedom. A controller architecture is coupled to the joystick position sensor and to the MRF joystick resistance mechanism. The controller architecture is configured to: (i) command the MRF joystick resistance mechanism to increase the joystick stiffness when the joystick is moved into a first predetermined detent position to generate a first MRF detent; and (ii) selectively activate a first detent-triggered function of the work vehicle based, at least in part, on joystick movement relative to the first MRF detent.

A shift device for a vehicle includes: a shift body that is moved and whose shift position is changed to a plurality of shift positions; a moving unit that moves the shift body; and a restricting body that restricts movement of the shift body by the moving unit at a predetermined shift position among the plurality of shift positions.

In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device. The joystick device includes, in turn, a base housing and a joystick, which is rotatable relative to the base housing and which is biased toward a joystick return position. An MRF joystick resistance mechanism is controllable to vary an MRF resistance force impeding movement of the joystick relative to the base housing, while a controller architecture is coupled to the MRF joystick resistance mechanism. The controller configured to: (i) selectively enable an operator adjustment of the joystick return position by a work vehicle operator; and (ii) when enabling the operator adjustment of the joystick return position, command the MRF joystick resistance mechanism to maintain the MRF resistance force at a predetermined level until the operator adjustment of the joystick return position is terminated.
