An apparatus for adjusting the operating position of a cultivator tool includes a tool bar with a frame secured thereto, a tool arm pivotally mounting the cultivator tool on the frame, a bracket having a plurality of holes therein mounted on the frame, and a tiltable lever arm mechanism pivotally mounted on the frame. The latter includes a lever having a first end portion constituting a handle, a second end portion, and a detent pin adapted to engage the holes in the bracket. A spring assembly yieldingly urges or tilts the bracket and lever together so the pin normally engages one of the holes. A handle extension can be installed to apply additional leverage, if needed. When the second end portion is connected to the frame by torsional spring, the downpressure exerted on an implement mounted on the frame can be varied. In another embodiment, a linkage bar pivotally connects the second end portion of the lever with the tool arm and allows the apparatus to raise and lower the tool.
