ABSTRACT:
A hammer plow is provided with a series of disks spaced along and rotatable with a sleeve that turns about an axle on a number of bearings located therebetween. Each of the disks has a plurality of hammers rotatably attached thereto, which are free to rotate in complete circles. The rotatable length of the hammers is shorter than the distance from the points of attachment to the disks to the sleeves or spacers therebetween. A hammer striking an obstruction in ground to be plowed will not break, but is free to counter-rotate relative to the disk to which it is attached. Numerous agricultural and construction grading operations can be performed in a single pass of the device over ground to be plowed.
