A baler of the type for forming cylindrical bales is improved by the use of a combine type pickup which more effectively lifts the crop from the ground for insertion into the main baler housing. Between a feeder housing of the combine type pickup and the main baler housing is provided a transportation section under which is provided a belt to ensure that any material falling from the transportation section is caught by the belt and carried rearwardly for collection in an auger and fan assembly. The auger and fan assembly provides a low pressure within the baler housing which is substantially fully enclosed so that all material is kept within the baler and prevented from escaping. The collected material in the fan is carried through a duct to a discharge cyclone dropping the material back into the transportation section for carrying into the baler housing for baling. The frame of the baler is mounted upon steerable wheels which allow the pickup to be arranged at an angle to the swath and allow the pickup to be steered across the swath to ensure that it properly follows the swath while the tractor continues in a straight line.
A baler for forming cylindrical bales from crop material picked up from the field comprising a frame, ground wheels mounted on the frame for transportation of the frame across the ground in a working direction, a pickup mounted on the frame for picking up crop from the ground and forming a crop flow for baling, a main baler housing having a feed opening into which the picked up material is introduced and drive means mounted within the main baler housing for driving the material to rotate about an axis to form a bale which is cylindrical about said axis, means for releasing a formed bale from the baler housing, the housing being substantially closed except for said feed opening, fan means for drawing air from the housing such that air is drawn into the housing from at least one opening therein so as to tend to retain crop material within the housing and means for transporting crop material drawn by the fan means for return to the crop flow for baling in said main baler housing.
