| 摘要 |
Snow plow apparatus is described having segmented blade means comprising a plurality of bits. Each bit is connected to a vertically disposed shank having a triangular cross-section. The shank is slidably mounted in triangularly-shaped retention means carried by the plow moldboard. Bias means urges the shank and bit to its normal downward position. Each bit is independently mounted so that it can be vertically displaced when it encounters a high point in the roadway or an obstruction. The bias means urges the bit downwardly again when the obstruction is cleared.
