  • Publication number: 20140288789
    Abstract: A method of automating unloading for a mobile farm implement is presented. The method includes determining whether the speed of the mobile farm implement is below a first threshold. In response to a determination that the speed of the mobile farm implement is below the first threshold, a conveyor is moved to an operating position, where it is used to unload agricultural material from the mobile farm implement. Upon termination of the unloading of the agricultural material, the controller folds the conveyor to a storage or transport position.

  • Patent number: 5590721
    Abstract: A conservation tillage tool, including a main frame and a rear frame pivotally mounted on the main frame disposed to support a number of soil working implements in sequence. The main frame is supported by ground wheels attached to the rear section of the main frame. The wheels are movable with respect to the main frame to move the latter between a raised transport position and a number of lowered working positions. A tongue and hitch unit connect the main frame to a prime mover, and a leveling mechanism operably interconnects the main frame, ground wheels and tongue for maintaining the main frame level at any of its positions. A spring-cushioned linkage operably interconnects one of the implements at the front of the main frame with one of the implements mounted on the rear frame for simultaneously raising and lowering those two implements between transport and working positions.

  • Patent number: 5156216
    Abstract: A conservation tillage tool including a frame disposed to support a number of soil working implements in sequence. The frame is supported by ground wheels attached to the rear section of the frame. The wheels are movable with respect to the rear section of the frame to move the frame between a raised transport position and a number of lowered working positions. A hitch attached to a tractor supports the front section of the frame, and a pivotally attached tongue interconnects the front section and the hitch. A leveling mechanism interconnects the rear section, the front section and the pivotally attached tongue. The leveling mechanism is a four-bar linkage that applies a force at the pivotal connection of the tongue to the front section as the wheels move to raise or lower the rear section thereby maintaining the frame substantially level with respect to the ground.

  • Patent number: 4926617
    Abstract: An apparatus for wrapping round hay bales includes a load supporting frame having means for mounting to a three-point hitch and a generally horizontally extending dispenser arm. An elongated spindle is rotatably mounted on the frame for engagement with a round hay bale along its longitudinal axis. A spinner plate is also rotatably mounted on the frame coaxially with the spindle and includes prongs for engaging an end of the hay bale. A hydraulic motor is provided for rotating the spinner plate which in turn rotates the hay bale on the spindle. The motor also moves a sheet material dispenser assembly along the dispenser arm at a predetermined rate to helically wrap the material on the exterior of the bale.
