Abstract:
1. A cold planer comprising: a frame having a front frame end and a back frame end; ground engaging propulsion elements coupled to the frame; a cutting mechanism coupled to the frame and including a housing defining a cutting chamber, and a rotatable cutter positioned within the housing and configured to cut material of a substrate underlying the cold planer; an anti-slabbing mechanism coupled to the frame and including an upwardly oriented base plate extending across a front side of the cutting chamber, a forwardly projecting plow, and a plurality of skids, and the anti-slabbing mechanism being vertically adjustable between a raised position and a lowered position and supported at a fixed orientation relative to a plane extending horizontally beneath the frame, at each of the raised and lowered positions; and a conveyor mounted to the base plate and being pivotable relative to the base plate, wherein the plurality of skids are arranged in a first subset positioned on a first outboard side of the plow, and a second subset positioned on a second outboard side of the plow, and downwardly depend from the base plate such that the plurality of skids define a substrate contacting footprint of the anti-slabbing mechanism, for applying a slabbing opposition force to uncut material of the substrate, and wherein the plurality of skids each include a mounting plate and a curved runner plate attached to the mounting plate, the curved runner plate having a central arcuate segment.
