A field grain cart is expandable for increasing holding capacity and contractible for providing transportability. The field grain cart includes a hopper including a center section, one or more expandable side sections that are movably attached to the center section, a base section that is disposed underneath the hopper, a floor conveyor that is disposed in the hopper, and a spout that is in communication with the hopper.

A grain cart is provided with an internal frame and a method of constructing a grain cart with an internal frame is provided. The grain cart can have a support frame, ground wheels, a hitch assembly, and a storage hopper supported on the support frame. The storage hopper can have a spine member running along the center portion, corresponding pairs of rib members connected at intervals along the spine member and a plurality of panels connected between adjacent rib members. The storage hopper can be constructed by connecting a plurality of rib members to a spine member, connecting a cross brace across corresponding pairs of rib members, inserting panels between adjacent rib members, and connecting the panels to rib members.

A control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.

A farm implement having an auger assembly that includes a first auger section with a first auger shaft and a first helical flight array, a second auger section with a second auger shaft and a second helical flight array, and a joint that releasably connects the first auger shaft to the second auger shaft when the auger assembly is in an operating position. When the auger assembly is set in the operating position, a leading edge of the first helical flight array opposes a trailing edge of the second flight array, and the leading edge is spatially separated from the trailing edge by a gap. The auger assembly further includes a first flight extension detachably mounted to the leading edge of the first helical flight array and/or a second flight extension detachably mounted to the trailing edge of the second helical flight array.
