The FFC cold planer by Paladin Construction Group attaches to a skid steer loader for the milling of asphalt and concrete surfaces. The hydraulic attachment is designed to mill down frost heaves, concrete and asphalt joints, and full-depth utility cuts. The cold planer uses a V-shaped pick pattern on the drum, where the teeth are evenly spread for a smooth, balanced operation. Four teeth are mounted on both outside drum edges to accommodate the highest wear areas. The V-shaped pattern helps carry material over the drum and behind the planer to clear the working area of milled material and reduce re-milling of material. Minimizing re-milling reduces horsepower requirements and maximizes the performance of both the skid steer and planer attachment. Standard flow models are available in 12- and 16-inch cutting widths to operate with hydraulic flows of 13 to 16 gpm. High-flow models are available in cutting widths from 16 to 36 inches and operate with flows from 24 to 45 gpm. Properly matching the attachment to the machine is critical in high-production work attachments like cold planers, advises Paladin.
