Apparatus for creating a ditch or furrow for agricultural use, including an implement pulled by a tractor. Generally, an implement includes a plow, a roller, and a wheel, such as a packer wheel. A plow is located towards an implement front end, and a wheel is located towards an implement back end, typically with the plow coaligned with a wheel. A roller is located on one or both sides of the plow wherein a frame supports the configurations of the plow, roller, and wheel.

A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

A structural element for a housing structure of a heating device. The structural element is at least essentially, especially completely, developed as a foam part, preferably as a thermoplastic casting foam part. In addition, a housing structure is described, which has a corresponding structural element, preferably at least two corresponding structural elements. Moreover, a heating device is described that includes at least one corresponding structural element and/or a corresponding housing structure. In addition, a method for mounting a corresponding housing structure is described.

Certain embodiments of the invention are related to creating a ditch or furrow for agricultural use. Certain embodiments include an implement pulled by a tractor. Generally, an implement includes a plow, a roller, and a wheel, such as a packer wheel. A plow is located towards an implement front end, and a wheel is located towards an implement back end. In certain embodiments, a plow is coaligned with a wheel. A roller is located on one or both sides of the plow in coalignment with a wheel. In certain embodiments, a frame supports the configurations of the plow, roller, and wheel.

A roller ring (8) for a roller (3,4) of a soil-tillage apparatus (1) comprises two rotationally symmetrical body halves (9) arranged opposite one another. Each body half (9) has a flange-shaped profile portion (10) extending in the radial direction (R), against which the body halves (9) abut over the entire surface. At least one profile portion (10) is divided into an inner contact portion (12) as well as an adjoining outer edge portion (13). The body halves (9) are at least partially connected by means of a substance-to-substance bond (15) radially on the inner side of the contact portion (12).

A roller for the agricultural soil cultivation has at least one support body that is rotatably mounted about an axis of rotation and multiple compaction rings arranged spaced apart from one another next to one another on the support body for compacting the ground and intermediate rings arranged between adjacent compaction rings. At least one first intermediate ring and a second intermediate ring with different diameters and/or different widths are provided. The roller includes at least one ring unit, which includes at least one compaction ring and at least one, in particular second, intermediate ring. The intermediate ring is connected to at least one adjacent compaction ring in a materially bonded manner or configured integrally with the compaction ring.
