<p>The track eraser is fitted to soil marking implements for levelling tracks, left by a tractor. The track eraser consists of discs which rotate on both sides of the track to be filled. The disc shafts, which are parallel to the ground, are so inclined to the direction of travel that viewed in the direction of travel, the discs are arranged in a V-shaped manner. There are several overlapping discs and the shafts of all discs have the same inclination to the direction of travel. The discs are sprung and the walking height is adjustable.</p> |
