摘要

The bar has an universal joint (15) for rotating a ramp arm (9) with respect to a frame (5) around a horizontal axis (A1) and a vertical axis (A2). Jacks (V1,V2) permit to rotate the arm with respect to the frame selectively around the axes (A1,A2). The axes are merged with axes of the universal joint. The jacks have respective ends connected with the arm or frame by ball pivots situated on corresponding axes. An independent claim is also included for an agricultural sprayer comprising spray bar.
