Abstract

An adjustable ridger for a cultivator includes an elongated ridger frame adapted to mount to the sweep member of the cultivator. The frame has a top bracket with an elongated slot extending therethrough. The slot has a width and a longitudinal axis. A plurality of setting holes in the top bracket are spaced apart along the longitudinal axis of the slot, each setting hole having a diameter greater than the width of the slot. A bottom bracket is spaced apart from the top bracket on the frame and has a guide hole therein. An elongated pull pin, having a stepped outer diameter with first and second diameter portions, is insertable through the slot in the top bracket and into the guide hole in the bottom bracket to act as a hinge pin. The second diameter portion is larger than the first diameter portion and yet smaller than the diameter of the setting holes. At least one wing pivotally mounts on the pull pin between the top and bottom brackets. Thus, the wing can be angularly adjusted relative to the frame by partially withdrawing the pull pin from the top bracket, moving it to a new setting hole, and allowing the second diameter portion of the spring-loaded pin to be urged into the desired setting hole. This adjustment mechanism does not require disassembly of the ridger wing assembly or removal of the pull pin from the guide hole.
