ABSTRACT:
Closely spaced cultivating tools are mounted along a tool bar and each tool may be locked in a raised position relative to the ground or may be lowered into floating engagement with the ground during use of the implement. A small tool bar is mounted parallel to a larger tool bar and the cultivating tools are slidably clamped on the small tool bar. Improved mounting structure allows each cultivating tool to be mounted on the small tool bar without having to slide each cultivating tool onto or off of the tool bar from the ends of the tool bar and without having to disassemble the mounting structure. The tool bar assembly includes row indicia for indicating where the tools are to be located along the tool bar and which tools should engage the ground and which tools should be raised away from the ground for various cultivating operations on row crops. A tool angling mechanism allows selective adjustment of the angle to the line of draft of each tool without the use of wrenches or other hand tools.
