A scarifier device includes a scarifier comprising a scarifier support frame having a plurality of downwardly depending axially secured scarifying teeth. An integrated roller device having a compaction roller on a roller support frame is pivotally coupled to the scarifier support frame. A hydraulic arm is positioned between the scarifier support frame and the roller support frame to articulate the roller device between a deployed position and a retracted position. Methods of making and using the scarifier device are also disclosed.

A one-way clutch assembly comprises a clutch casing including a first plate coupled to a second plate, such as clutch inner and clutch outer plates. The first and second plates have a common central axis, the first and second plates are spaced apart along the common axis to define an interior. The assembly also includes a ratchet plate disposed in the interior between the first and second plates, the ratchet plate has the same common axis and is displaceable along the axis within the interior. A first torque transfer mechanism, such as a set of mating splines is used to rotationally couple the ratchet plate to the first plate. A second one-way torque transfer mechanism is used for releasably coupling the ratchet plate to the second plate, the second transfer mechanism including a set of fixed flat and angled portions formed on a ratchet plate surface opposite the second plate and a complimentary set of fixed flat and angled portions formed on a second plate surface opposite the ratchet surface. The assembly also has a biasing mechanism for monitoring the relative axial displacement between the ratchet plate with respect to the second plate, the biasing mechanism for providing an axial force for engaging the ratchet surface with the second plate surface. Accordingly, engagement of the complimentary flat and angled portions effects the one-way torque transfer between the ratchet plate and the second plate. The biasing mechanism can include mechanical and hydraulic actuation.

A scarifier/grader apparatus comprises, in combination, a tractor connected through a 3-point hitch to a scarifier/grader attachment wherein:

Gravel scarifying and levelling device

A scarifier comprises a plurality of supported, downwardly depending, axially secured scarifying teeth supported on a scarifying-tooth supporting frame connected in loose fitting relation to a tractor to thereby operatively impart a first component of lateral play at respective scarifying tip ends. The frame also includes a bracket engaging respective shank portions of the scarifying teeth en axially secured relation with sufficient degrees of lateral freedom to provide a second component of lateral play to spaced apart scarifying points of respective ones of those teeth.
