SCRAPER BLADE HAVING TRIP EDGE AND FLOATING EDGE
A scraper blade assembly having a moldboard combined with a plurality of surface engaging assemblies. Each surface engaging assembly includes a cutting-edge section configured to contact the ground during operation and a linkage assembly configured to allow the surface engaging assembly to move between its various positions. Each surface engaging assembly is movable around a pivot axis between an operational position and a tripped position wherein obstacles are allowed to pass underneath the cutting-edge section. In addition, each cutting-edge section is linearly movable between an extended position and a retracted position wherein the cutting-edge section floats linearly (generally upward) to contour to the ground. The linkage assembly is operatively combined with a biasing member. The biasing member urges the surface engaging assembly toward the operational position and the cutting-edge section toward the extended position.
