Abstract
A tractor includes a track assembly having a frame, an idler wheel mechanically coupled to the frame, a drive wheel mechanically coupled to the frame, an endless track disposed around the idler wheel and the drive wheel, and a number of mid-rollers interposed between the idler wheel and the drive wheel. The tractor also includes a first protection member having a first upper edge and a first lower edge. The first protection member is secured to the frame such that a portion of the frame is positioned behind the first protection member. The tractor further includes a number of first guard members secured to the first protection member so that (i) the first guard members extend downwardly beyond the first lower edge toward the endless track and (ii) the first guard members are spaced apart from each other along the first lower edge such that a gap is defined between adjacent first guard members.
