The clamping mechanism may comprise a tine angled portion engaging component operable to engage an upper surface of the angled end portion of the tine member. The upper and lower clamping arms may comprise at least one upper ridge and at least one lower ridge for engaging in contact with a first portion and a second portion respectively of outward facing surface regions of the tine support structure.

A tillage implement has a frame connectable to a towing vehicle and at least two transverse rows of secondary tillage tools mounted on the frame, the at least two transverse rows comprising a row of main rollers mounted on the frame rearward of all other rows of the at least two transverse rows. The implement also has a transverse row of auxiliary rollers mounted rearward of the row of main rollers, the transverse row of auxiliary rollers independently pivotable vertically about a transverse pivot axis. The implement has at least one ground-engaging wheel. Independent pivoting of the row of auxiliary rollers allows an operator to increase tillage/field finish on the go or as needed.

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.
