An agricultural tractor having a three-point hitch with a top link. The tractor is provided with a lifting block adjacent the three-point hitch. The lifting block has a retractable cable which can be used to assist in the raising or lowering of the top link, to allow for easy manipulation of the top link by an operator. In addition, the cable of the lifting block can be used to assist in the coupling of a rear attachment system of the tractor with relatively heavy implements.

An agricultural harvesting head for mounting on a feederhouse of an agricultural combine has an adapter frame coupled to and supported on a center frame section with four links. Each link extends between and is pivotally coupled to the center frame section at a forward end of the link and is pivotally coupled to the adapter frame at a rear end of the link.

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.

An agricultural implement includes a tool bar assembly configured to couple to a main frame of the agricultural implement and a pull frame. The tool bar assembly includes a first tool with a height that is adjustable relative to a soil surface. The pull frame includes a hitch assembly configured to be coupled to a work vehicle, a mounting portion configured to be removably coupled to the main frame of the agricultural implement, and a hollow portion that extends over the first tool bar between the hitch assembly and the mounting portion while the tool bar assembly and the pull frame are coupled to the main frame. The hollow portion is configured to accommodate one or more conduits.

A hitch comprising: a) a first member having a first top surface, an opposing first bottom surface, a first side, an opposing second side, a first end, a distal second end, and at least one channel proximate the first end and extending from the first side through to the second side. A second channel proximate the second end and extending from first top surface to the bottom surface; and b) a second member next to the second end and having a predetermined thickness, the second member having a third end, a fourth end, and a third channel next to the fourth end. The third channel extends through the predetermined thickness. A portion of the second member is rigidly affixed to a portion of the first member, so that the second bottom surface and the first top surface are at an acute angle .

A system for controlling a ground speed of an agricultural sprayer includes a speed setting device for commanding a selected ground speed of the sprayer when operating within a speed-range mode associated with a ground speed range. The speed setting device is movable across a plurality of positions, with each position being associated with a different ground speed within the ground speed range. A maximum range speed of the ground speed range is lower than a maximum ground speed of the sprayer. As such, the system includes a speed override input device for commanding that the ground speed of the sprayer be increased to the maximum ground speed. When an override input is received from the speed override input device, the computing system controls the operation of a sprayer drive system to increase the ground speed of the sprayer from the selected ground speed to the maximum ground speed.

A lock proving system provides a positive indication when a locking mechanism has correctly latched a removable attachment to an agricultural machine, the attachment being a header for a combine harvester for example. The locking mechanism includes a locking element that is shiftable into a locking position in which, provided the attachment is mounted to the machine with the correct alignment, the locking element acts upon a lock proving mechanism that is mounted to the attachment. The lock proving mechanism delivers mechanical feedback to the machine, the action of which is detected by a sensing device mounted upon the machine.

A method for providing improved ride control for a work vehicle when transporting a drawn implement may include monitoring a load applied through a drawbar-related component(s) of the work vehicle while the drawn implement is being transported, wherein the drawn implement is located at a transport position relative to a driving surface of the work vehicle such that a ground engaging tool of the drawn implement is located above the driving surface. The method may also include detecting a variation in the monitored load over time, comparing the detected load variation in the monitored load to a predetermined load variance threshold and controlling an operation of at least one of an implement suspension system of the drawn implement or a vehicle suspension system of the work vehicle so as to reduce the detected load variation in the monitored load when the load variation exceeds the predetermined load variance threshold.
