Abstract: A trailer incorporator for towing behind a slurry wagon for incorporating slurry into soil on farms comprising a manifold for distributing the slurry to a plurality of injectors mounted on the trailer, a plurality of coulters on the trailer and adjustments to position the injectors, coulter and wheels on the trailer and for tilting the trailer fore and aft. The trailer has one connection point to the slurry wagon to allow a pivotable connection for ease of making turns with the trailer when the coulters and plows are engaging the soil. The trailer removes weight from the slurry wagon allowing for a wider distribution of slurry by a wider trailer, and removing weight from the slurry wagon reducing soil compaction and allowing for more slurry to be put in the slurry wagon without overloading it. The trailer therefore allows for more efficient operations.

Abstract: A self-unloading grain cart having a horizontal auger and a vertical auger for unloading grain from the cart. The cart having a plurality of gates for accessing a portion of the auger at one time so as not to overload the auger. The cart also having a clutch for engaging or disengaging the horizontal auger so that the vertical auger can be turned independently from the horizontal auger. The starting and stopping of the movement of grain when unloading the cart is thereby enhanced to prevent spillage and for quicker restarts with lower power requirements.

Abstract: An improved grain cart is able to hold more grain with reduced field compaction to derive greater yield from a farm field. The grain cart includes a frame which supports a grain hopper and is supported by a plurality of wheels, some of which are steerable so the cart also has an acceptable turning radius.
