  • Patent number: 5303662
    Abstract: A minimum tillage farm implement capable of being used for plowing, cultivating, planting and insecticide and herbicide and fertilizer application, which includes a tool bar frame having three parallel spaced apart laterally positioned tool bars held together by detachable interconnecting frame members. Coulters, chisel plows and discing pairs are mounted in series to the front tool bar. Variable width rototillers are attached to the middle tool bar and planters are attached to the rear tool bar, both serially alligned with the discing pairs. The coulters, chisel plows, discs and rototillers prepare a fine seed bed, even in stalks and stubble, to allow beneficial planting of row crop seeds by the planters. In a second mode the front and rear tool bars are detached leaving only the middle tool bar with rototillers, which can be adjusted for width and position to perform as cultivators of the areas between adjacent seed beds.
