Rather than there being a right angle transition at the end of the unloading tube, from tube to boot (typical on all other machines i.e. Deere, Case, etc.), the grain exits the Cat's unloading tube, straight out the end of the tube (like a grain tank fill auger). At the end of the tube, there is a boot that deflects the grain atleast another 2 feet, allowing the grain to cascade into the wagon_truck without having to make an acute transition that could potentially cause grain damage to certain crops, especially when very dry. .
