A portable roller groover assembly may include an assembly frame. At least one wheel unit may be provided on the assembly frame. The wheel unit may have at least one wheel selectively deployable in an extended position to deploy the assembly frame in a towing configuration and a retracted position to deploy the assembly frame in a grooving configuration. A towing hitch interface may be provided on the assembly frame. The towing hitch interface may be configured to facilitate coupling of a towing vehicle to the assembly frame in the towing configuration. A grooving hitch interface provided on the assembly frame may be configured to facilitate coupling of the towing vehicle to the assembly frame in the grooving configuration. A groover on the assembly frame may have a plurality of spaced-apart groover disks.

A sheath for a soil working roller includes a plurality of sheath segments mounted or mountable to surround a roller body of the soil working roller and following one another in the circumferential direction. A plurality of roller tools is arranged on an outer side of the sheath segments and at least one part of the roller tools includes an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder. A fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder.

A soil conditioner system includes a bit body. A first buffer bit and a second buffer bit may be mounted in a back-to-back configuration on the bit body. The first buffer bit and the second buffer bit may be mounted in respective recesses formed in the bit body on opposite sides of the bit body. The bit body includes a mounting surface at a second end of the bit body that is used to rigidly couple the bit body with a horizontally rotatable member such that the bit body extends transversely away from an outer surface of the horizontally rotatable member. The bit body includes a first side and a second side disposed on opposing sides of the bit body to face opposite directions of horizontal rotation of the horizontally rotatable member. The first and second sides are positioned between the mounting surface and the first buffer bit and the second buffer bit, respectively.
