• a leading idler wheel assembly pivotably connected to the frame member;
• a trailing idler wheel assembly pivotably connected to the frame member;
• a leading idler actuator assembly operatively connected between the frame member and the leading idler wheel assembly;
• a trailing idler actuator assembly operatively connected between the frame member and the trailing idler wheel assembly;
• a support wheel assembly at least indirectly connected to the frame member and disposed between the leading idler wheel assembly and the trailing idler wheel assembly;
• and
• an endless track extending around the leading idler wheel assembly, the trailing idler wheel assembly, and the support wheel assembly.
