Abstract
An agricultural machine for smoothing ruts, such as are produced in a field by center pivot sprinkler irrigation systems, comprises a pair of rotary tillers arranged in a unique frame for traveling over and along respectively opposite sides of the rut as such tillers are rotated toward each other to break up clods of soil ridged above the rut at opposite sides thereof and to largely fill and smooth the rut. A guide shoe carried by the frame midway between the rotary tillers is preferably provided to travel along the rut and maintain the rotary tillers at proper working positions, and a hood with outriggered side walls hinged thereto for outward swinging movement preferably covers the rotary tillers.
Claims21
An agricultural machine for smoothing ruts in a field, comprising a structural frame adapted to travel over and along a rut in the field;
- a pair of laterally spaced rotary tillers carried by said frame and spaced so as to operate on earth material along opposite sides of a rut to be smoothed, said tillers being mounted for rotation in opposite directions so their bottoms rotate toward each other and each having sets of blades adapted to dip into and to push said earth material toward and into the rut while breaking up any clods along the rut;
- means for powering said machine and for causing it to be transported about the field at working level;
- and a guide shoe of box formation open at the top and at its rear with side walls bowed outwardly and a closed front, the bottom of the guide shoe sloping upwardly and forwardly, said side walls being pivoted at their forward ends for positional adjustment inwardly and outwardly, and said guide shoe being carried by the frame between and in advance of the rotary tillers for running within and along the rut as the machine travels.
An agricultural machine for smoothing ruts in a field, comprising a structural frame adapted to travel over and along a rut in the field;
- a pair of laterally spaced rotary tillers carried by said frame and spaced so as to operate on earth material along opposite sides of a rut to be smoothed, said tillers being mounted for rotation in opposite directions so their bottoms rotate toward each other and each having sets of blades adapted to dip into and to push said earth material toward and into the rut while breaking up any clods along the rut, said structural frame having a forward transverse frame member substantially defining the width of the machine, a shorter rear transverse frame member substantially coextensive with the portion of said structural frame that carries the rotary tillers, and a longitudinal frame member rigidly interconnecting said forward and said rear transverse frame members;
- and means for powering said machine and for causing it to be transported about the field at working level, said powering means being located at one side of the machine and the rotary tillers being located at the opposite side of the machine.
An agricultural machine for smoothing ruts in a field, comprising a structural frame adapted to travel over and along a rut in the field;
- a pair of laterally spaced rotary tillers carried by said frame and spaced so as to operate on earth material along opposite sides of a rut to be smoothed, said tillers being mounted for rotation in opposite directions so their bottoms rotate toward each other and each having sets of blades adapted to dip into and to push said earth material toward and into the rut while breaking up any clods along the rut, said structural frame having a forward transverse frame member, a relatively short rear transverse frame member substantially parallel with said forward transverse frame member and having one end positioned substantially directly behind an end of said forward transverse frame member, so that said rear transverse frame member and the coextending portion of said front frame member define the width of the laterally offset portion of the structural frame, said structural frame being provided at its forward end with a three-point hitch for attachment to a conventional farm tractor, and having a portion offset laterally from the portion provided with the three-point hitch so as to be centered behind a rear wheel of a farm tractor hauling the machine, the rotary tillers of the pair of rotary tillers being carried by said offset portion of the structural frame at opposite sides, respectively, of the center of said offset portion;
- and means for powering said machine and for causing it to be transported about the field at working level.
