Transparent plow blade
摘要:
A plow blade for snow plowing or other plowing applications is constructed prepared from a transparent material to reduce plow weight and to permit the normal lighting of the plow vehicle to be seen through the plow blade, thus eliminating the need for auxiliary lighting. The plow blade is especially suitable for use with small plows, such as those designed for use with small four-wheel drive passenger cars. In the preferred embodiment, a transparent, replaceable plastic plow face member is supported by a light weight frame.
