Patent CZ-125894-A3 (CZ)
Title: Harrow, especially smoothing harrow
Inventor: SCHWEIGER GEORG
IPC: A01B19/02
Filed: 1992-11-20
Abstract: In a harrow (1) having a large working width, the lateral outer parts of the harrow are folded up into a transport position around folding axes (16a, 16b). In order to protect the joints (14a, 14b) against excessive stresses caused by bending moments, the carrying frame (10) of the harrow (1) is provided with front and rear cross-beams (11 and 12), of which at least the front cross-beam (11) laterally extends beyond the joints (14a, 14b) of the traction beam (3) and is itself provided with joints (14c, 14d), so that it can also be folded. The front cross-beam (11), which is stiffened against bending moments, protects the traction beam (3) in the manner of a bumper or fender. If required, it also absorbs movements contrary to the traction direction (16c) by means of chain sections (15) with which in particular the outer part of the traction beam (3) is suspended from the adjacent outer part (11b, 11c) of the cross-beam. The cross-beam is stiffened by longitudinal members (20a, 20b) that support the outer parts (11b, 11c) of the cross-beam and whose base on the rear cross-beam (12) is in turn braced by traction members (23a, 23b) with respect to the three-point suspension (8) of the tractor (9), so that it cannot move in the opposite direction to the direction of traction (16c).
