A work vehicle includes a mechanical front wheel drive (MFWD) and a controller unit for automatically controlling the MFWD based at least on a MFWD request signal, a speed ratio request signal, and a brake-status signal. The MFWD request is overridden if the speed ratio request is for a predetermined speed ratio (such as fourth gear), and the overriding of the MFWD request is interrupted if the brake-status signal indicates that a brake of the work vehicle is applied.

Automatic control of mechanical front wheel drive using speed ratio

A vehicle is disclosed that includes a transmission and a gear selector. A controller determines the position of the gear selector and other conditions of the vehicle to control the operation of the transmission.

Directional transmission control with ECU authorization

Method and differential-lock control apparatus for differential lock control are disclosed. A control unit is arranged for communication with an engine speed sensor, a differential-lock activation control, and a differential lock. The control unit is adapted to allow for reduction of an engine speed to a desired engine speed if the engine speed is at least a threshold engine speed in response to receipt of an activate-differential-lock request signal, and adapted to subsequently output an activate-differential-lock control signal to the differential lock so as to command activation of the differential lock.

Method and apparatus for differential lock control

A system for reliably enabling an implement controller for a work vehicle having a swivel seat with at least two angular positions. The system includes an implement controller for controlling a work implement, seat position detector for determining the positions of the swivel seat, an ignition switch and an implement controller toggle switch. The system is capable of enabling the implement controller under ideal enablement conditions and non-ideal enablement conditions. Ideal enablement conditions exist when the implement controller toggle switch is toggled to an implement controller enabling state while the ignition switch is on and the seat is properly positioned. Non-ideal enablement conditions exit when the implement controller toggle switch is put in an implement controller enabling state in the absence of ideal enablement conditions.
