An agricultural vehicle for picking or harvesting a product includes a motor, a plurality of tires, a transmission mating the motor to the plurality of tires, an accumulator operable to store the product, a module builder operable to receive the product from the accumulator, and a frame supporting the accumulator and the module builder. The frame defines a hatch through which an operator is capable of accessing the motor and/or the transmission. The agricultural vehicle is operable to transition between a first state and a second state. In the first state, the module builder and the accumulator prohibit access through the hatch. In the second state, the module builder and the accumulator are rotated relative to the frame and provide access through the hatch.
