ABSTRACT:
A trailer, for a header-equipped implement, has a T-shaped main frame, with the head of the T being defined by a beam extending in the direction of travel and with the stem of the T centered between a pair of loading ramps having first end portions coupled to the beam for pivoting about a fulcrum such that the ramps are moved from a loading to a transport position by the weight of the implement when the implement is backed up the ramps to a loaded position resting on the beam and in engagement with respective bumper/latch bars fixed to the beam. Stability of the trailer is maintained during loading of the implement by parking stands, at opposite ends of the beam, which are either manually or automatically moved between support and stored positions. The wheels are each mounted to an arm having a latch hook secured thereto and which moves into latched engagement with a respective one of the bumper latch/bars to secure the implement to the trailer when the arms are raised by the implement lift cylinders to lower the header onto the frame stem. The implement has a swing tongue used to tow the trailer/implement combination endwise relative to the header. Mounted to one of the ramps is a storable trailer tongue which may be used to tow the trailer when it is empty.
