A resilient device is positioned inside the swivel bar where the pivot is combined to the bracket assembly and extends through the swivel bar. At least one agricultural implement and preferably two agricultural implements are connected to the swivel bar on opposite sides of the pivot. ## Claims ### Claim 1 A manure injection system comprising: a toolbar operatively connectable to a tanker by a hitch; a bracket assembly connected to the toolbar; a swivel bar pivotally connected to the bracket assembly and positioned parallel to the toolbar for pivoting in a horizontal plane with respect to the toolbar and adapted for receiving at least one agricultural implement connectable to the swivel bar; a resilient device positioned inside the swivel bar; and a pivot combined to the bracket assembly and extending through the swivel bar and engaging the resilient device. ### Claim 2 (depends on 1) The manure injection system of claim 1, wherein the resilient device is a torsion block that comprises: an outer casing comprising a plurality of sides; an inner tube comprising a plurality of sides; and a plurality of inserts each one of which is positioned between one of the plurality of sides of the inner tube and the outer casing. ### Claim 3 (depends on 2) The manure injection system of claim 2, wherein the outer casing of the torsion block further comprises four sides; and wherein the inner tube further comprises four sides; and further comprising four inserts each one of which positioned between one of the four sides of the inner tube and the outer casing. ### Claim 4 (depends on 3) The manure injection system of claim 3, wherein the inner tube is rotated forty five degrees with respect to the outer casing such that each one of the four sides of the inner tube is rotated forty five degrees with respect to a corresponding one of the four sides of the outer casing. ### Claim 5 (depends on 2) The manure injection system of claim 2, wherein the pivot extends through the inner tube of the torsion block. ### Claim 6 (depends on 2) The manure injection system of claim 2, wherein when the swivel bar rotates with respect to the pivot and the torsion block dampens movement of the swivel bar and urges it back to position. ### Claim 7 (depends on 2) The manure injection system of claim 2, wherein the torsion block is fully contained in the swivel bar to protect the plurality of inserts inside the torsion block from dust. ### Claim 8 (depends on 2) The manure injection system of claim 2, wherein the plurality of inserts each comprise elastomeric inserts each of which when compressed returns to its uncompressed state. ### Claim 9 (depends on 1) The manure injection system of claim 1, wherein the bracket assembly further comprises of a pair of mounting plates spaced apart vertically and positioned on opposite sides of the swivel bar each of which comprising a through hole aligned with the pivot which extends there-through. ### Claim 10 (depends on 9) The manure injection system of claim 9, wherein the resilient device comprises of a torsion block comprising of an outer casing comprising a plurality of sides, an inner tube comprising a plurality of sides, and a plurality of inserts each one of which is positioned between one of the plurality of sides of the inner tube and the outer casing, and wherein the pivot extends through the through hole in the pair of mounting plates and through the inner tube of the torsion block. ### Claim 11 (depends on 10) The manure injection system of claim 10, wherein the pivot comprises of a cross-section comprising a plurality of sides equal to the plurality of sides of the inner tube. ### Claim 12 (depends on 11) The manure injection system of claim 11, wherein the inner tube comprises four sides and the pivot comprises four sides. ### Claim 13 (depends on 12) The manure injection system of claim 12, wherein the pivot is fixed to the bracket assembly. ### Claim 14 (depends on 13) The manure injection system of claim 13, wherein the pivot is fixed to one of the pair of mounting plates of the bracket assembly. ### Claim 15 (depends on 14) The manure injection system of claim 14, and further comprising: a pair of bushings disposed on the pivot and positioned between the pivot and the inner tube of the resilient device; and a pair of wear plates disposed on the pivot and positioned between the pair of mounting plates and the swivel bar. ### Claim 16 (depends on 1) The manure injection system of claim 1, wherein the swivel bar is adapted to receive two agricultural implements with one agricultural implement attached to each side of the swivel bar separated by the pivot. ### Claim 17 A manure injection system comprising: a toolbar operatively connectable to a tanker by a hitch; a swivel bar pivotally connected to the toolbar for pivoting in a horizontal plane and adapted for receiving at least one agricultural implement connectable to the swivel bar; a bracket assembly connected to the toolbar and comprising of a pair of mounting plates spaced apart vertically and positioned on opposite sides of the swivel bar each of which pair of mounting plates comprising a through hole; a resilient device comprising of a torsion block comprising of an outer casing comprising a plurality of sides, an inner tube comprising a plurality of sides, and a plurality of inserts each one of which is positioned between one of the plurality of sides of the inner tube and the outer casing; a pivot comprising of a cross-section with a plurality of sides equal to the plurality of sides of the inner tube and extending through the through hole in the pair of mounting plates and through the inner tube of the torsion block that is positioned inside the swivel bar; a pair of bushings disposed on the pivot and positioned between the pivot and the inner tube of the resilient device; and a pair of wear plates disposed on the pivot and positioned between the pair of mounting plates and the swivel bar. ### Claim 18 (depends on 17) The manure injection system of claim 17, wherein the outer casing of the torsion block further comprises four sides; and wherein the inner tube further comprises four sides; and further comprising four inserts each one of which positioned between one of the four sides of the inner tube and the outer casing. ### Claim 19 (depends on 18) The manure injection system of claim 18, wherein the inner tube is rotated forty five degrees with respect to the outer casing such that each one of the four sides of the inner tube is rotated forty five degrees with respect to a corresponding one of the four sides of the outer casing.
