Abstract: Saddle type self-steer axle systems equipped wagons may include two or more axles and may be backed up due to reversing caster. Such systems may provide increased stability by providing four points of contact. Further, such systems may provide improved weight distribution in that weight may be distributed over four points as opposed to three points. In addition, such systems may provide increased safety by raising the rollover threshold to that of the tow vehicle. Such systems may allow a tow vehicle to carry its full allowable gross weight while towing its full allowable tow weight. In addition, a centrally pivoting saddle style hinge system may reduce the actuator force that may be needed to change the caster from forward to reverse and vice versa.
