Portable roller groover assembly

A portable roller groover assembly for coupling to a towing vehicle in a towing configuration and alternative coupling to the towing vehicle in a grooving configuration for formation of grooves or furrows in soil, comprising:

• an elongated, rectangular assembly frame including:
• a frame front, a frame rear, a leading frame end and a trailing frame end;
• an elongated front base frame member at the frame front;
• an elongated rear base frame member at the frame rear;
• a leading end frame member extending between the front base frame member and the rear base frame member at the leading frame end;
• a trailing end frame member extending between the front base frame member and the rear base frame member at the trailing frame end, the front base frame member, the rear base frame member, the leading end frame member and the trailing end frame member disposed within a frame plane;
• and
• a frame interior formed by the front base frame member, the rear base frame member, the leading end frame member and the trailing end frame member;
• a pair of elongated, parallel, spaced-apart upper frame members carried by the front base frame member and the rear base frame member, respectively;
• a pair of wheel units carried by the front base frame member and the rear base frame member, respectively, of the assembly frame, each of the pair of wheel units including at least one wheel selectively deployable in an extended position to deploy the assembly frame in the towing configuration and a retracted position to deploy the assembly frame in the grooving configuration;
• a towing hitch interface carried by the leading end frame member of the assembly frame at the leading frame end, the towing hitch interface configured to facilitate coupling of the towing vehicle to the assembly frame in the towing configuration;
• a grooving hitch interface carried by the front base frame member and a corresponding one of the pair of upper frame members of the assembly frame at the frame front, the grooving hitch interface configured to facilitate coupling of the towing vehicle to the assembly frame in the grooving configuration, the grooving hitch interface comprising:
• first and second pairs of elongated, parallel, spaced-apart side hitch plates vertically spanning the front base frame member and the upper frame members of the assembly frame;
• a pair of spaced-apart upper hitch plates on the assembly frame, the upper hitch plates disposed between the first and second pairs of the side hitch plates on the upper frame member of the assembly frame:
• a pair of side hitch pins engaging the first and second pairs, respectively, of the side hitch plates;
• and
• an upper hitch pin engaging the pair of upper hitch plates, the side hitch pins and the upper hitch pin configured to facilitate pinned connection of a grooving hitch on the towing vehicle to the side hitch plates and the upper hitch plates in coupling of the grooving hitch to the grooving hitch interface;
• and
• a groover having;
• a single elongated groover body carried by the assembly frame and disposed in the frame interior, the groover body coextensive with the assembly frame and including a first groover end at the leading frame end and a second groover end at the trailing frame end;
• a plurality of spaced-apart groover disks extending from the groover body, each of the plurality of spaced-apart groover disks protruding from the frame interior and disposed at least partially beyond the frame plane of the assembly frame, each of the plurality of spaced-apart groover disks including a pair of disk sides tapering in an angled trajectory to an annular outer disk edge;
• and
• the groover body having a plurality of vacant groover body segments extending between the plurality of spaced-apart groover disks, each of the plurality of vacant groover body segments defining an inter-disk space between adjacent ones of the plurality of spaced-apart groover disks, the inter-disk space devoid of the plurality of spaced-apart groover disks.
