At least two laterally spaced bearing standards resiliently connecting the shaft to the beam. Each bearing standard includes a spring whose first extremity is secured to the beam, a curved central portion for positioning a free ended second extremity of the spring in spaced relation beneath the first extremity and a bearing assembly carried toward the free ended extremity of the spring for rotatably supporting the shaft. The bearing assembly is mounted toward the second end of the spring for rocking movement about an axis disposed in an acute angle relative to the horizontal direction of movement of the harrow assembly.
