The socket connected to the base top surface of the attachment and encompassing at least a portion of the ball. The ball may be connected to a stem which may comprise a hole which serves as a connection point between the joint and an end of a hydraulic ram. ## Claims ### Claim 1 A joint (500) for connecting an attachment (100) to a hydraulic ram (10), said attachment comprising: a base (110) having a base first edge, a base second edge opposite the base first edge, a base first end, and a base second end defining a base horizontal plane having a base top surface (116) and a base bottom surface (117) with a base wall spanning a distance between the base top surface and the base bottom surface; the joint comprising a ball (510) and a socket (520); and at least a first plurality of teeth (130) and a second plurality of teeth (140); and wherein the socket is connected to the base top surface; wherein the socket encompasses at least a portion of the ball; wherein the ball comprises a stem (540) extending from a ball surface substantially opposite the portion of the ball which is encompassed by the socket; wherein the stem comprises a hole (541) passing into the stem substantially parallel with a stem central axis (542), said hole consisting of a plurality of smooth surfaces, and said stem being configured to removably connect the joint to an end of the hydraulic ram by passing the end of the hydraulic ram into the hole; wherein the first plurality of teeth extend from the base bottom surface along at least a portion of the base first edge; and wherein the second plurality of teeth extend from the base bottom surface along at least a portion of the base second edge. ### Claim 2 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, said socket comprising a first socket component (521) integrally connected to the base top surface, and a second socket component (522) removably connected to the first socket component by one or more fasteners. ### Claim 3 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, wherein the first plurality of teeth are integrally connected to a first tooth plate, the second plurality of teeth are integrally connected to a second tooth plate, the first tooth plate is connected to the base along the base first edge by at least a first fastener, and the second tooth plate is connected to the base along the base second edge by at least a second fastener. ### Claim 4 (depends on 3) The joint for connecting an attachment to a hydraulic ram of claim 3, wherein the first plurality of teeth and the second plurality of teeth are each independently made of a material comprising steel. ### Claim 5 (depends on 4) The joint for connecting an attachment to a hydraulic ram of claim 4, wherein the base is made of a first material comprising aluminum. ### Claim 6 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, further comprising at least a third plurality of teeth (150) and a fourth plurality of teeth (160), wherein the third plurality of teeth extend from the base bottom surface along at least a portion of the base first end, and the fourth plurality of teeth extend from the base bottom surface along at least a portion of the base second end. ### Claim 7 (depends on 6) The joint for connecting an attachment to a hydraulic ram of claim 6, wherein the third plurality of teeth are integrally connected to a third tooth plate, the fourth plurality of teeth are integrally connected to a fourth tooth plate, the third tooth plate is connected to the base along the base first end by at least a third fastener, and the fourth tooth plate is connected to the base along the base second end by at least a fourth fastener. ### Claim 8 (depends on 7) The joint for connecting an attachment to a hydraulic ram of claim 7, wherein the third plurality of teeth and the fourth plurality of teeth are each independently made of a material comprising steel. ### Claim 9 (depends on 8) The joint for connecting an attachment to a hydraulic ram of claim 8, wherein the base is made of a first material comprising aluminum. ### Claim 10 (depends on 6) The joint for connecting an attachment to a hydraulic ram of claim 6, wherein the third plurality of teeth and the fourth plurality of teeth are each independently made of a material comprising steel. ### Claim 11 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, further comprising at least one spike (300) connected to and extending from the base bottom surface. ### Claim 12 (depends on 11) The joint for connecting an attachment to a hydraulic ram of claim 11, wherein the at least one spike comprises a plurality of spikes. ### Claim 13 (depends on 12) The joint for connecting an attachment to a hydraulic ram of claim 12, wherein the plurality of spikes are arranged in an “X” pattern along the base bottom surface. ### Claim 14 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, wherein the base is made of a first material comprising aluminum. ### Claim 15 (depends on 1) The joint for connecting an attachment to a hydraulic ram of claim 1, wherein the first plurality of teeth and the second plurality of teeth are each independently made of a material comprising steel. ### Claim 16 (depends on 1) A hydraulic ram comprising at least a first attachment and a second attachment wherein the first attachment and the second attachment are each independently connected to the hydraulic ram by a joint of the type called for in claim 1, the first attachment is connected to a hydraulic ram first end, and the second attachment is connected to a hydraulic ram second end opposite the hydraulic ram first end.
