Abstract

A baler comprises two winding spaces disposed side-by-side. In use, a pick-up device picks up crop from a swath and feeds it to one of the spaces. A pivotable wall portion comprising powered rollers initiates winding of a bale and pivots upwardly about an axis as the bale grows. Other powered rollers surrounding the winding space assist in the formation of the bale. When the bale is complete it is bound with twine, a door is raised by a ram and the bale is discharged. As soon as winding of a bale in one of the spaces is complete, the pick-up device in whole or part is moved relatively laterally with respect to the winding spaces so that crop is then fed to the other winding space while the completed bale is bound and discharged.
