  • Patent number: 4838360
    Abstract: A minimum tillage implement attaches to the tool bar of a planter device to allow topping of the rows, tilling of the rows, planting and chemical application to be accomplished in a single pass over the rows of a field. The minimum tillage implement comprises a shaper for topping the rows of the field, and a reel for tilling the planting area of the row. Adjacent the top of the shaper is a substantially horizontal, forwardly-projecting lip portion which serves to prevent dirt from going over the top of the shaper. The reel follows the shaper and has a number of blades spaced substantially evenly about a shaft, and has tabs interposed between adjacent blades. The tabs allow the reel to roll as smoothly as if it had twice as many blades, without the clogging that might occur with a reel having so many blades.
