Tapered bearings are provided for use on each end of each link arm on an agricultural seed row planter mounted on a toolbar. The bearing is a low friction material and greaseless. The tapered design of the bearings allows the bearings to be adjusted as wear occurs, by tightening the link arm mounting nut which extends through the tapered bearing. The tapered bearing has an increased life and reduced maintenance, as compared to prior art roller bearings.

A towed agricultural implement including a first headstock element for connection to a towing vehicle, a second headstock element supporting a chassis member provided with a plurality of working implements, a pivot pin for connecting the first headstock member and the second headstock member and defining a horizontal axis of rotation between the first headstock member and the second headstock member, in which the second headstock member has a lateral centre of gravity offset from the axis of rotation. A compensating structure is provided between the first headstock member and the second headstock member to offset the unbalanced loads caused by the lateral centre of gravity being offset from the axis of rotation.

A power lift for an agricultural tractor includes a supporting structure configured to be mounted on the agricultural tractor. A left lower link, a right lower link, and an upper link are coupled in a pivotally movable manner, wherein the left and the right lower links and the upper link include coupling elements for attachment of an agricultural attachment. The left and the right lower links are rotatably coupled to one another via a lifting shaft, the lifting shaft being aligned with a lower link pivot axis. The left and the right lower links are pivotable by an actuating element which runs between at least one of the lower links and a support point of the supporting structure jointly about the lower link pivot axis in relation to the supporting structure.

A system is suitable for connecting multiple implements to a three-point hitch of mobile machinery for controllable side-shifting movement of the connected implements. The system comprises first, second and third apparatuses, each apparatus comprising a first framework, a slidable second framework laterally slideable relative to the first framework, at least one connector supported by the slidable second framework for connecting the slidable second framework to one of the implements, and at least one driver connected to the first framework and the slidable second framework for driving the slidable second framework laterally back and forth relative to the first framework. The second apparatus is attached to one side of the first apparatus and the third apparatus is attached to the other side of the first apparatus.

A towed agricultural working tool with a central frame element, a headstock and left and right hand side frame elements connected to the central frame element, each of the side elements supporting at least one processing unit, the central frame element being connected at, at least one connecting location for pivoting movement with respect to the headstock in which one or more friction elements are arranged between the central frame element and the headstock at one of the at least one connecting locations. This has as an advantage that the pivoting movement of the central frame with respect to the headstock, in particular due to induced yaw, is reduced.

An agricultural tractor having a component storage system. The storage system including a storage bracket which is attached to the pick-up hitch of the tractor. The storage bracket allows for the storage of components of the pick-up hitch when not in use, e.g. a pick-up hitch hook, a drawbar. As the bracket is attached to the pick-up hitch itself, the components are stored in a convenient location for the tractor operator, to allow for hitch components to be changed in a relatively fast manner.

The use of self-powered, autonomous vehicles in agricultural and other domestic applications is provided. The vehicles include a self-propelled drive system, tracks or wheels operatively connected to the drive system, a power supply operatively connected to the drive system, an attachment mechanism for attaching equipment to the vehicle, and an intelligent control operatively connected to the drive system, power supply, and attachment mechanism. The vehicle is configured to connect to the equipment to perform agricultural operations based upon the equipment. Multiple vehicles can be used in a field at the same time. Furthermore, the invention includes the ability to move one or more of the autonomous vehicles from field to field, home to field, or from generally any first location to a second location.

A mechanical system attaches to a tractor and, upon activation of a hydraulic ram, rotates implement-engaging implement lift hooks to rotate an attached agricultural implement upwards towards 90 degrees for inspection and maintenance. The system can be secured in its raised and rotated position via a locking pin. The implement is returned to its original position through removal of the locking pin, reversal of the hydraulic ram and disconnection of the implement lift hooks.

One or more techniques and/or systems are disclosed for a hitch system that couples a vehicle to an implement powered by the vehicle using a driveshaft supplying power from a power output to the implement. The hitch system comprises a front portion and rear portion, with a mid-yaw pivot coupling the front and rear portions. The front portion couples to a drawbar engaged with the vehicle, and the rear portion couples with the implement. The mid-yaw pivot can be disposed substantially equidistant from a power output of the vehicle and a power input to the implement. This arrangement can provide, during operation, for the angle between the power output and driveshaft to be substantially equal to the angle between the power input and driveshaft. This may provide for improved performance in the implement, including reduced vibration, lower weight, and less maintenance.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.
