Haymaking machine with hinging mounting - has driving shafts coupled together by double universal joint

摘要

The machine has two or more driving shafts supported by a beam on the frame and a mounting swinging upwards on the beam. The two shafts are coupled together by a double universal joint. The latter can incorporate an intermediate piece with fork ends hinging on the shaft fork ends. The support can be arranged to swing up through 90 deg. from the beam into the transport position, and about an axis clear of a horizontal plane through the centre line of the shaft, which line it intersects.
