  • Apparatus for folding over corn stalk stubble and the like
    Patent number: 6648078
    Abstract: The present invention relates to a device which may be mounted to the front of a tractor and which is operative to fold over corn stalks and the like before they engage the front tires of the tractor. The device positions dragging units in front of each of the front tires of the tractor, whereby the dragging units are dragged over the ground in front of the tires when the tractor is moving. The weight of each of the dragging units is sufficient to cause it to substantially fold over corn stalks and the like prior to their engagement with the front tires of the tractor, thereby greatly minimizing wear to the tires caused by engagement with the corn stalks and the like.
