Caterpillar Attachments now includes in its range of products the Cat® Silage Defacer, developed for Cat compact wheel loaders, skid steer loaders, compact track loaders, and Multi-Terrain loaders. The Silage Defacer is designed to cut and shave large silage bunks in order to improve material retention and to ensure more consistent feed quality, leaving a clean surface on the bunk and eliminating large amounts of oxygen penetration that can cause mold.

Available worldwide in three width configurations—72, 84, and 96 inches (1.8, 2.1, and 2.4 m), the Silage Defacer uses a heavy-duty frame to house a front-mounted cutting drum. The drum is driven by a system of dual, hydraulic motors and dual, heavy-duty roller chains to optimize torque and reliability. The drive motors are mounted behind drum and within the frame for protection from damage, and the chains feature cotter-pin master links for extended chain life.

High-tensile-strength, hardened-steel teeth on the drum—5 inches (127 mm) in length—are arranged in a helical pattern for even load distribution and to ensure efficient cutting and facing, leaving a finely textured finished product for feed. The teeth are positioned at a precise angle to ensure minimal drum stalling and material cling. A standard cross-over relief valve dampens hydraulic pressure spikes and diverts high pressure away from the host machine.
