Abstract
Unique self-propelled soil working machines are disclosed. In certain exemplary embodiments the self propelled soil working machine includes a tool carrier which is actively adjustable to provide variable downward force on a soil working tool via a suspension element which is further passively responsive to accommodate motion of the tool in response to external force. In certain exemplary embodiments, the tool carrier is configured to adjust the working depth and pitch of the tool. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.
Claims21
An apparatus comprising:
- a self-propelled soil working machine including a frame and an operator station;
- front and rear ground supporting wheels coupled with the frame, a least one of the front and rear ground supporting wheels configured to propel the machine;
- a linkage coupled with the frame and coupled with a soil working tool, the soil working tool being adjustably positioned by the linkage rearward of the front wheels and forward of the rear wheels, the linkage including a suspension element accommodating movement of the tool in response to external force;
- and
- an adjustment mechanism coupled with the linkage and configured to adjust the linkage;
- wherein adjustment of the adjustment mechanism emulates the addition or subtraction of weight exerting downward force on the tool.
A self-propelled soil working machine comprising:
- a plurality of surface contact wheels carrying a chassis;
- a carrier assembly coupled with the chassis, the carrier assembly including a suspension coupled with the chassis and a soil working tool coupled with the suspension;
- and
- an adjustment mechanism coupled with the carrier assembly and configured to adjust the position of the tool and to vary force applied to the tool at least in part based upon compression of the suspension.
