An agricultural row unit having a support frame, a structural support housing coupled to the support frame, and a swing arm having a leading end pivotably coupled to the structural support housing. An agricultural tool is coupled to a trailing end of the swing arm, and a hydraulic actuator is mounted to and fully enclosed within the structural support housing. The hydraulic actuator adjustably urges the agricultural tool downwardly toward a soil surface such that vertical pivoting movement is permitted in response to terrain changes in the soil surface.

1. An agricultural row unit comprising: a support frame;a structural support housing coupled to the support frame, the structural support housing including separate left and right housing sections;a swing arm having a leading end pivotably coupled to the structural support housing;an agricultural tool coupled to a trailing end of the swing arm; anda hydraulic cylinder mounted to and enclosed within the left and right housing sections of the structural support housing, the left and right housing sections being attached to each other, the structural support housing bearing forces imparted on the agricultural tool by the soil surface, the hydraulic cylinder adjustably urging the agricultural tool downwardly toward a soil surface such that vertical pivoting movement is permitted in response to terrain changes in the soil surface. 2. The agricultural row unit of claim 1, further comprising: an accumulator positioned adjacent to the hydraulic cylinder within the structural support housing;a pivot support located within the structural support housing;a hydraulic hose routed within the structural support housing;wherein the hydraulic cylinder includes a hydraulic-fluid cavity, the hydraulic cylinder further including a hydraulic ram extending into the hydraulic-fluid cavity of the hydraulic cylinder, the hydraulic ram having an axial fluid passageway through which hydraulic fluid flows between the hydraulic-fluid cavity and the perpendicular pivot component;wherein the pivot support couples the hydraulic hose to the hydraulic ram and to the accumulator such that the hydraulic fluid flows between the hydraulic hose, the accumulator, and the hydraulic cylinder. 3. The agricultural row unit of claim 1, wherein the structural support housing is mounted to a leading side of the support frame via a bracket primary mounting bracket. 4. The agricultural row unit of claim 1, wherein the structural support housing is mounted to a mounting spacer, the mounting spacer being attached to a primary mounting bracket, the primary mounting bracket being attached to the support frame. 5. The agricultural row unit of claim 1, wherein the agricultural tool is a cutting wheel. 6. The agricultural row unit of claim 1, further comprising a trailing floating linkage mounted to the support frame, the trailing floating linkage having a row cleaner with one or more wheels selected from a group consisting of a closing wheel and a toothed wheel. 7. The agricultural row unit of claim 1, further comprising a gauge wheel mounted, via a gauge wheel arm, to a leading end of the swing arm. 8. The agricultural row unit of claim 1, wherein the hydraulic cylinder includes a ram extending into a hydraulic-fluid cavity within the hydraulic cylinder, the hydraulic-fluid cavity receiving pressurized hydraulic fluid for advancing the hydraulic cylinder in a first direction that pivots the swing arm downwardly toward the soil surface. 9. The agricultural row unit of claim 8, further comprising an accumulator positioned adjacent to the hydraulic cylinder within the structural support housing, the accumulator having a fluid chamber containing a pressurized gas for allowing the hydraulic cylinder to retract in a second direction that pivots the swing arm upward away from the soil surface. 10. The agricultural row unit of claim 8, further comprising a mechanical spring positioned adjacent to the hydraulic cylinder within the structural support housing, the mechanical spring biasing the hydraulic cylinder in a second direction that pivots the swing arm upward away from the soil surface. 11. The agricultural row unit of claim 1, wherein the swing arm is coupled to the a leading end of the structural support housing at a pivoting connection, the pivoting connection including a pivot bearing, a seal wear ring, and a grease seal. 12. The agricultural row unit of claim 1, further comprising a hydraulic hose routed within the structural support housing and coupled to the hydraulic cylinder. 13. An agricultural row unit for use with a towing frame hitched to a tractor, the row unit comprising: a support frame for attachment to the towing frame;a structural support housing coupled to a leading end of the support frame, the structural support housing including separate left and right housing sections, the structural support housing providing structural support for a hydraulic cylinder mounted within the left and right housing sections, the left and right housing sections being attached to each other; anda swing arm having a pivoting end coupled to a leading end of the structural support housing, the swing arm having a trailing end attached to a coulter wheel for opening a furrow in a soil surface, the hydraulic cylinder causing the coulter wheel to float over a change in the soil surface by adjusting vertically in response to the change. 14. The agricultural row unit of claim 13, further comprising: an accumulator enclosed within the structural support housing;a hydraulic hose for supplying hydraulic fluid and enclosed within the structural support housing; anda pivot support enclosed within the structural support housing and in fluid communication with the accumulator and the hydraulic hose;wherein the hydraulic cylinder includes a hydraulic-fluid cavity, the hydraulic cylinder further including a hydraulic ram having an axial fluid passageway in fluid communication with the pivot support and the hydraulic-fluid cavity of the hydraulic cylinder. 15. The agricultural row unit of claim 14, wherein the hydraulic-fluid cavity receives pressurized hydraulic fluid from the hydraulic hose, via the pivot support, for advancing the hydraulic cylinder in a first direction that pivots the swing arm downwardly toward the soil surface. 16. The agricultural row unit of claim 14, wherein the accumulator includes a fluid chamber containing a pressurized gas for allowing the hydraulic cylinder to retract in a second direction that pivots the swing arm upward away from the soil surface. 17. An agricultural row unit for use with a towing frame hitched to a tractor, the row unit comprising: a support frame;a structural support housing coupled to a leading side of the support frame, the structural support housing including separate left and right housing sections;a swing arm having a leading end pivotably coupled to a leading end of the structural support housing;a cutting wheel coupled to a trailing end of the swing arm for forming a furrow in a soil surface;a hydraulic cylinder mounted within the left and right housing sections of the structural support housing and including a ram extending into a hydraulic-fluid cavity within the hydraulic cylinder, the left and right housing sections being attached to each other, the hydraulic-fluid cavity receiving pressurized hydraulic fluid for advancing the hydraulic cylinder in a first direction that pivots the swing arm downwardly toward the soil surface; andan energy storage device positioned adjacent to the hydraulic cylinder within the structural support housing, the energy storage device allowing the hydraulic cylinder to move in a second direction that pivots the swing arm upward away from the soil surface. 18. The agricultural row unit of claim 17, wherein the energy storage device is selected from a group consisting of a mechanical spring and a gas-charged pressure vessel. 19. The agricultural row unit of claim 17, further comprising a hydraulic hose routed within the structural support housing and coupled to the hydraulic cylinder. 20. The agricultural row unit of claim 17, further comprising a trailing floating linkage mounted to the support frame, the trailing floating linkage having a row cleaner with one or more wheels selected from a group consisting of a closing wheel and a toothed wheel.
