An auxiliary control station for a rear dispensing concrete truck that controls the truck's steering, braking, and throttle. A seat with controls accessible from the seat may be positioned outside of the cab, such as to allow control of the truck from a position with an unobstructed view of the rear of the truck. The concrete dispensing chute may be modified so as to allow mechanical control of the left and right swing of the chute. The auxiliary control station also controls the drum and positioning of the chute.
