Abstract:
A pump support coupler assembly for connecting a large displacement hydraulic pump to a tractor power take off device is provided. The pump support coupler assembly includes a coupler housing with front and back walls, and sidewalls. The high displacement hydraulic pump attaches directly or indirectly to the coupler housing back wall. A shaft extends longitudinally through the coupler housing. The shaft is coupled to an input shaft of the hydraulic pump at its first end and a power take off output shaft at its second end. A torque restraint strap extends between the coupler housing and a tractor drawbar, and prevents the coupler housing from rotating about its longitudinal axis. In this configuration, the power take off output shaft supports the pump support coupler assembly and the hydraulic pump, and since the pump is attached to the coupler housing, the pump input shaft is not subjected to bending-type loads.
Abstract:
The invention provides an innovative yet straightforward approach to driving the seed distribution system in planters which feature hinged winged extensions. The flexibility of the hinged winged extensions may allow the planter to adjust to the contours of a field and to fold to facilitate transport of the planter. In one embodiment, for example, the invention may provide a mechanical coupling between several sections of a seed drive shaft which may support and be driven by a hydraulic motor for each of the winged sections. The seed drive system may also be coupled to row units to synchronize and power the distribution of seeds by the planter.

Abstract:
A folding marker for connection to an agricultural implement toolbar with a marker shoulder pivot, an inner arm and a double acting hydraulic cylinder both pivotally connected to the shoulder pivot. A middle arm bracket is pivotally connected to the inner arm and the cylinder. A middle arm is connected to the middle arm bracket, with two beams extending from the bracket and terminating at an outer arm pivot, with a third beam connected between the bracket and a crossbrace. An outer arm pivot bracket is pivotally connected to the outer arm pivot, an outer arm connected thereto and having two legs connected between the outer arm pivot bracket and a plate assembly. The legs define a channel therebetween, and an adjustable arm is slidably connected within the channel. An extension element is insertable within the channel and lockable with the plate assembly, with a marking element connected thereto.

Abstract:
An apparatus and method for controlling positions of an implement and a marker associated with a work vehicle. The apparatus includes a hydraulic circuit coupled to a first cylinder that governs the position of the marker, a first valve coupled to a second cylinder that governs the position of the implement and also coupled to a first port of the circuit, and a second valve coupled to a second port of the circuit. The circuit is configured to isolate the first port of the circuit from secondary pressure supplied to the second port by way of the second valve, and further configured to isolate the primary port of the circuit from primary pressure supplied to the first port by way of the first valve. The primary pressure influences movement of both the marker and the implement, while the secondary pressure influences movement of the marker only.
Abstract:
An agricultural implement has a central section and wing sections with ground engaging tools. A hydraulic cylinder is disposed between the wings and the central frame to raise and lower the wings with respect to the central section. A hydraulic control circuit is coupled to the cylinder to provide a constant downforce to the wings over a range of pivotal ground working positions and to lift the wings above the ground to a non-ground engaging position thereby permitting the implement to be easily turned in the headlands of an agricultural field. When the lifting circuit is engaged, the downforce can be automatically removed from the wing sections permitting them to be raised more easily. The raising and lowering of the central section and wings can be staged, such that the central section is lowered first to prevent damage to ground engaging tools on the wing sections.
Abstract:
This invention teaches an improved collapsible farm implement of the type having a wheeled frame or cart and right and left side elongated toolbars pivoted at their inboard ends about vertical axes relative to the frame so as to allow toolbar rotation rearward through approximately a quarter turn between a fully elevated field use position disposed crosswise to the path of implement travel and a road transit position disposed parallel to the path of implement travel. A wheeled truck assembly is mounted near the outboard end of each toolbar for providing rolling support of the latter, and each wheeled truck assembly can be rotated relative to the toolbar about an axis disposed substantially normal to the toolbar through approximately a quarter turn operable to steer the outboard end of the toolbar, upon appropriate forward or rearward implement movement, between the respective fully elevated field use and road transit positions. To provide a compact collapsed implement, each toolbar is pivoted or rotated approximately a quarter turn about a horizontal axis disposed substantially parallel to the toolbar so as to raise and lower tool elements carried on the toolbars between a lowered, operative field use position adjacent the ground and a fully elevated field use position disposed substantially normal to the ground. Partial toolbar rotation is utilized during normal field operation to raise tool elements clear of the ground for turning at the end of field passes. A power cylinder is used to steer each wheeled truck assembly and to rotate each toolbar for raising and lowering the tool elements, and a flow divider is used to admit equal volumes of pressurized hydraulic fluid to the cylinders so that synchronized steering or tool element lift operation takes place.
Abstract:
An agricultural implement system is provided that includes a valve in fluid communication with first and second actuating cylinders and with first and second fluid conduits. The valve is configured to control fluid flow from the first and second fluid conduits to the first and second actuating cylinders. Furthermore, a controller is communicatively coupled to first and second pressure sensors and to the valve. The first pressure sensor is coupled to the first fluid conduit, and the second pressure sensor is coupled to the second fluid conduit. The controller is configured to determine whether the first fluid conduit or the second fluid conduit is supplying fluid to the valve based on signals from the first and second pressure sensors, and to automatically control fluid flow to the first and second actuating cylinders such that wheel assemblies are rotated to a desired angle relative to an implement frame.
