Abstract
A machine having a ground-engaging rotor may include a first swing arm and a second swing arm. A first end of the first swing arm may be pivotably coupled a frame of the machine at a first pivot and its second end may be coupled to the rotor. A third end of the second swing arm may be pivotably coupled the frame at a second pivot and its fourth end may be coupled to the rotor. A torsion bar and a crossbeam may both be coupled to the first swing arm and the second swing arm. At least one actuator may also be coupled to the crossbeam such that activation of the at least one actuator rotates the first swing arm about the first pivot, and the second swing arm about the second pivot, and deploy the rotor.
