AGRICULTURAL IMPLEMENT DRAWBAR MECHANISM |
摘要 |
A drawbar mechanism for coupling an earth-working tool to an agricultural implement is disclosed. The agricultural implement includes a frame and a source of hydraulic pressure. The drawbar mechanism includes an extendable and retractable hydraulic cylinder in fluid communication with the source of hydraulic pressure and having a first end pivotally coupled to the frame and a second end. A drawbar having a first portion pivotally coupled to the frame defines a working range. The drawbar having a second portion coupled to the earth-working tool. The second end of the hydraulic cylinder is pivotally coupled to the drawbar enabling a substantially constant down force throughout the working range of the drawbar.
