This is a detailed specification for a custom heavy-duty pusher plow with a 15-foot blade and a 56-inch inside barrel height. It requires an integrated weld-in JRB 416 coupler, with highly specific dimensions for end plates, mounting holes, and support gussets. The plow skin is formed from two mirrored 8GA steel halves with multiple press-broken brakes, vertical support ribs, and reinforcement plates. The assembly includes a 180-inch rubber blade secured by retainer plates and Grade 8 hardware, along with various gussets, lower reinforcements, and a blade angle for structural support. No timelines, budget amounts, or performance location are specified in the description.
