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; and
a 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.

Abstract
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.

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; and a 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. - View Dependent Claims (14, 15, 16)

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; and an 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. - View Dependent Claims (18, 19, 20)
