An agricultural implement includes a transversely extending frame forming at least a first frame section, a second frame section, and a third frame section, where the first frame section is disposed between the second and third frame sections. A pair of elongated gang assemblies are on the first frame section, an elongated gang assembly is on the second frame section, and an elongated gang assembly is on the third frame section. Each of the gang assemblies is horizontally adjustable relative to the frame. An actuator for each gang assembly operably controls the angular adjustment of the gang assemblies, and a fluid source supplies fluid to the actuators. The actuator on the second frame section is a master actuator for one of the actuators on the first frame section, and the actuator on the third frame section is a master actuator for the other actuator on the first frame section.

By providing a linear actuator in communication with a slide bar disposed in a channel, and by configuring multiple bars of a harrow to achieve an angle of rotation defined by the slide bar, the angle of rotation for smoothing tools of the harrow may be precisely controlled by the linear actuator. As a result, an infinite range of downward angles may be available for the smoothing tools for achieving various effects with the soil.

A method of controlling a mobile agricultural machine, the method comprising operating a row unit having a ground-engaging element to deliver product to a furrow formed by the row unit, receiving an indication of rotational speed of the ground-engaging element, determining that the rotational speed of the ground-engaging element is below a threshold, and controlling an action of the mobile agricultural machine based on the determination.

The invention relates to mechanisms used for propelling various working tools of agricultural machines. The mechanism includes a beam having at least three support surfaces and a platform with a working tool capable of moving along the beam on rollers rotatably mounted on the platform. Moreover, a tooth rack is rigidly attached to the beam with its teeth capable of interacting with a cogwheel mounted on the platform and shaped as a disk with bearings acting as the teeth of the gear. Besides, at least two support surfaces of the beam are oriented at an angle to the horizontal and perpendicular to the direction of rollers travel, with at least three rollers interacting with the support surfaces of the beam. This design enhances the operational reliability of the mechanism under various loads experienced by the working tool during its operation.
