An agricultural tool used to form furrows includes a generally cylindrical support and a plurality of tires. Each tire includes a sole by way of which the tire is mounted on the support, a tread opposite the sole (3) and two sidewalls that connect the tread to the sole. The sole, the tread (5) and the sidewalls jointly form a deformable casing. The tread of at least one of the plurality of tires has a generally domed shape. The sidewalls of this tire are generally inclined radially. The domed shape of the tread and the inclination of the sidewalls are such that the deformation of the casing urges the sole axially outward.

Disclosed herein are self-guiding roller devices and system for compressing a medium. In one aspect, the roller devices and systems include: an attachment frame having a first pivot portion and configured to connect to a powered machine; a roller assembly including at least one rotatable roller component and at least one roller frame having a second pivot portion being configured to connect to the first pivot portion; and a pivot member configured to connect the first and second pivot portions, the roller assembly being able to rotate 360-degrees about the attachment frame while being driven from behind by an attached powered machine. Also disclosed herein are methods of using the disclosed roller devices and systems.

A land roller implement is towed by an agricultural tractor for levelling land. The implement has a main frame and two wing assemblies pivotal from a working field position extending laterally outward in opposing directions from the main frame to a transport position extending rearwardly from the main frame. The implement has a set of transport wheels for transporting the rollers of the implement spaced above the ground in the transport position, the wheels including: (i) two leading wheels on the main frame, (ii) two trailing wheels at the outer ends of wing assemblies, and (iii) two steerable wheels supported on the wing assemblies forwardly of the trailing wheels. The steerable wheels can be controllably pivoted by an actuator into a transport configuration oriented for forward rolling in transport, while the other wheels are freely pivotal to shorten the turning radius of the towed implement.

An end wheel assembly for transforming an implement frame from a transport position to a field position is provided. The end wheel assembly can have an end wheel, a wheel pivot rotatably connected to the end wheel, a wheel member pivotally connected to the wheel pivot, at least one attachment bracket attached to the wheel member and pivotally attachable to the implement frame, a wheel actuator to raise and lower the end wheel assembly, and a guide plate. The guide plate can have a channel, a first end connected to the wheel member, and a second end connected to the wheel pivot. The channel can be positioned to receive a positioning member when the end wheel assembly is pivoted downwards and to rotate the guide plate causing the wheel pivot and end wheel to rotate relative to the wheel member and turn the end wheel outwards.
