Rotor deployment mechanism for a machine

A machine having a ground-engaging rotor, comprising:

• a first swing arm and a second swing arm symmetrically positioned about a longitudinal axis of the machine, wherein (a) the first swing arm includes a first end and a second end opposite the first end, the first end being pivotably coupled to a frame of the machine at a first pivot and the second end being coupled to the rotor, and (b) the second swing arm includes a third end and a fourth end opposite the third end, the third end being pivotably coupled to the frame at a second pivot and the fourth end being coupled to the rotor;
• a torsion bar extending substantially transverse to the longitudinal axis and coupled to the first swing arm at the second end and coupled to the second swing arm at the fourth end;
• a crossbeam extending substantially transverse to the longitudinal axis and coupled to the first swing arm at a location between the first end and the second end and coupled to the second swing arm at a location between the third end and the fourth end;
• and
• at least one actuator coupled to the crossbeam such that activation of the at least one actuator synchronously rotates the first swing arm about the first pivot and the second swing arm about the second pivot to move the rotor with respect to the frame of the machine, wherein rotation of the first swing arm and the second swing arm in a first direction rotates the torsion bar in a second direction opposite to the first direction.
