A disk harrow having a carriage frame and diverging forward and rear secondary frames extending laterally with respect to a travel direction. Gangs of disk blades are connected to and supported by the secondary frames. A portion of the outermost portion of the forward secondary frame is articulated relative to the remainder of the frames and has a ground support wheel allowing its height to be independently controlled relative to the remainder of the secondary frames.

A cultivator is provided for cultivating a field. The cultivator can have a frame with a tow assembly so that the cultivator can be towed by a tractor. A cultivating assembly can be provided pivotally attached to the rear of the frame. The cultivating assembly can have a plurality of discs that engage and penetrate the soil beneath the cultivating assembly. The cultivating assembly can have a center section pivotally connected at the to the rear end of the frame, a first wing section pivotally connected to one side of the center section, a second wing pivotally connected the other side of center section where all the sections have discs connected to them. A pair of ground wheels can be provided connected to the center section so that the ground wheels are positioned in front of the cultivating assembly when it is being used to cultivate a field.

An agricultural planter with seed trencher discs and seed delivery mechanism is disclosed which deposits seeds or product in the trench opened by the discs. Multi-functional wheels are mounted rearward of the trencher discs on an adjustable arm so as to provide a depth gauging function for the trencher discs. The wheels are mounted to run at an angle and distance corresponding to the disc blades so as to movably scrape clean dirt and debris from the disc blades opening the trench. The wheels are positioned to move displaced trench soil back over the trench while effectively running at a position where dirt and debris try to lift out of the opening trench due to the action of the disc cutting blades.

A towable tool includes a frame extending over a width in an X-axis direction, a length in a Y-axis direction, and a height in a z-axis direction. A plurality of ground-contacting support wheels are rotatably coupled with the frame. A plurality of ground-working discs each rotatably coupled with a respective rigid shank. Each rigid shank is received and selectably retained in a respective receptacle of the frame.

Presently described is a device (1) for adjusting the angle of disc sections for agricultural harrows which comprises at least one articulation element (10) configured to be pivotally attached to a beam (200) of an agricultural harrow (2), the articulation element (10) being configured to be pivotally attached to an adjustment shaft (20), thus allowing the angular adjustment of the beams of the agricultural harrow sections in both a horizontal plane and a vertical/transverse plane, comprising simple construction when compared to solutions existing in the prior art, making use of few components to allow both adjustments, and providing simple, practical and fast operation, requiring few manipulation steps.

A disk harrow having a carriage frame and diverging forward and rear secondary frames extending laterally with respect to a travel direction. Gangs of disk blades are connected to and supported by the secondary frames. A portion of the outermost portion of the forward secondary frame is articulated relative to the remainder of the frames and has a ground support wheel allowing its height to be independently controlled relative to the remainder of the secondary frames.
