A three-point hitch for an agricultural tractor includes a lift arm, a lower link arm, and a lift spindle disposed between lift arm and lower link arm for transmitting a pivoting movement performed on the lift arm to the lower link arm. The lift spindle includes a first fastening section articulated on the lift arm and a second fastening section articulated on the lower link arm. An elongated hole is formed in the second fastening section along a longitudinal direction of the lift spindle, and a mounting pin extends through a fastening opening in the lower link arm and is mounted in the elongated hole. At least two locking regions are spaced apart from one another and formed along the elongated hole for receiving a shaped feature provided on the mounting pin. A movement of the lower link arm along the elongated hole is blocked when the shaped feature is received in one of the locking regions.

An apparatus for connecting an implement to a three point hitch of mobile machinery comprises two frameworks, a first framework and a second framework. The first framework is disposed in a first plane and comprises at least two parallel, vertically-spaced apart, laterally extending rails. There are three attachments supported by the first framework for attachment to the three-point hitch. The second framework is slidable generally in the plane of the first framework and is mounted on the rails to slide laterally along the rails. At least two connectors are supported by the slidable second framework for connecting the second framework to an implement that can be pulled or pushed by the mobile machinery. A driver is connected to the first framework and connected to the second framework for driving the second framework laterally back and forth along the rails of the first framework.

In certain aspects the present disclosure provides lawn/garden spraying devices and methods for their use. The support arrangement is configured to be mounted to a trailer hitch of a lawn and garden tractor, ATV or UTV. The support enables the user to selectively fix the height and angle of the nozzles on a spray boom. The support forms an adjustable Z arrangement.

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.

An implement coupler including an electrical generator configured to generate electric power in response to a mechanical force provided by a power takeoff of a work vehicle. The implement coupler includes a support frame and an adjustment mechanism operatively connected to the support frame, wherein the adjustment mechanism is configured to adjust the position of the support frame with respect to the work vehicle. The generator is located on the support frame and is operatively connected to the power takeoff. The implement coupler further includes a drive shaft connected to the power takeoff and to the generator, an electrical coupler electrically coupled to the generator to provide access to the generated electrical power wherein the electrical coupler includes an output configured to provide the generated electrical power, and a line coupler including a connector configured to couple to source of material and to deliver the material.

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.

One or more sensors identify a characteristic of a towed implement using non-visual electromagnetic radiation, auditory detection or temperature detection. The characteristic of the implement is compared to a reference characteristic to determine whether the implement has a problem. If so, control signals are generated to control a controllable subsystem based upon the identified problem.

In one aspect, a system for monitoring frame levelness of an agricultural implement may include first and second sensors configured to detect first and second parameters indicative of forces exerted on first and second ground engaging tools of the implement by the ground, respectively. The system may also include a controller configured to monitor a parameter differential between the first and second parameters based on measurement signals received from the first and second sensors, with the monitored parameter differential being indicative of at least one of pitch or roll of a frame of the implement. The controller may be further configured initiate a control action associated with adjusting the pitch and/or the roll of the frame based on a magnitude of the monitored parameter differential to adjust an orientation of the frame relative to the ground.

There is provided a singly steerable, serpentine steel track crawler. The single-track crawler can steer independently in a serpentine fashion. Two or more single crawler tracks side-by-side can be transformed into a multi-track crawler vehicle. The single-track crawler or multi-track crawler vehicle can be fitted with rubber tires for plying on paved roads. This makes it a versatile, multi-terrain vehicle for agriculture and earth-moving applications.

An agricultural machine or implement has a main frame section and at least one wing section, each having lift cylinders. A main shank frame may be pivotally attached to the main frame section and may have hydraulically adjustable gauge wheels. Wing shank frames may be pivotally attached to the wing sections and may also have hydraulically adjustable gauge wheels. Bypass circuits may be used to individually adjust the lift cylinders and gauge wheel cylinders. A controller or controllers is used to purge air from the lift cylinders, gauge wheel cylinders, cylinders used to raise the shank frames for transport, and from the bypass circuits. The purge routine may be selectable as individual steps, hydraulic subsystem purges, or as one automatic purge routine.
