A module builder of an agricultural vehicle includes a chamber operable to support and form a product. A wrap is feedable into the chamber through a pinch point, the pinch point partially defined by a rotatable roller. A belt at least partially defines a wrap path. The wrap is configured to move along the wrap path to surround the product in the chamber. A gas flow system and/or a reversing belt is operable to direct the wrap from the pinch point toward the wrap path.

A control system for controlling a pitch of a plurality of fan blades of a variable pitch fan driven by an engine of a harvester. The control system comprises first, second, and third feedback devices that provide first, second, and third feedback signals indicative of at least one harvester temperature, an ambient temperature, and an engine load. A controller is operable to receive the first, second, and third feedback signals, lookup an initial pitch setting, generate an initial pitch setting signal, and compare the harvester temperature to a harvester temperature limit and generate a fan reversal signal if certain conditions are met.

Row unit lift structure includes electrohydraulic proportional valves connected to an electronic controller which receives inputs from a manual raise/lower switch, a rate response potentiometer, and height control potentiometers in the cab. Signals are also received from row unit height sensing transducers, a tachometer and shaft rotation sensors. When the units are lowered and operational, the controller compares the signals from the height sensing transducers with the signals from the height control potentiometers and sends an electrical control signal to the proportional valves to maintain a selected row unit height. The magnitude of the control signal and thus the rate of correction of height are determined by the rate response potentiometer and the amount of variation between the actual and desired row unit height.
