The sleeve member is slidably mounted upon the length of the trailing arm and is selectively fastened to the trailing arm at various positions therealong whereby the depth of the soil engaging tools in the soil is determined. A compression spring is utilized to biasly extend the extensile arm arrangement, and the upper portion of the extensile arm has an over-center locking device whereby the extensile arm may be rapidly lengthened or shortened, and respectively locked in such condition, thereby respectively engaging or disengaging the soil engaging tools in the soil.
