Abstract:
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.
