Abstract
In a farm harrow, a U-shaped clamp mounts channel-shaped bars to harrow tine supporting shafts. The shafts transversely extend through longitudinal channel-shaped carrier arms and are rotatably mounted therethrough. The bars are mounted within each respective carrier arm channel and introduce, in cooperation with the carrier arm, rotative limits to the respective shafts. The bars allow the rotative limits of the respective shafts to be adjusted accordingly so as to maintain a desired drag angle for the attached harrow teeth during forward harrow movement as well as allowing the harrow to back up without the attached harrow teeth digging in.
