  • DEPTH ADJUSTMENT MECHANISM FOR FARM IMPLEMENTS
    Publication number: 20040000412
    Abstract: An adjustment mechanism for use with farm implements or other equipment utilizes a series of alternating teeth and notches arranged in an arcuate pattern about an axis of adjusting movement on a movable member and a pair of arcuately spaced latching bars on a stationary member of the mechanism. The bars are individually shiftable into and out of engagement with the teeth and notches and are spaced apart such a distance that when either of the bars is in registration with a notch, the other bar is in registration with a tooth. Springs yieldably bias the bars toward the teeth and notches so that the bar aligned with a notch will snap down into the notch while the other bar resides in a standby position abutting the outer end of its tooth.
