Drum-wheel harvester

Big rolling harvester about 6m long on four fat riveted drum wheels, a bulbous thresher body with a wide toothed intake reel at the front and a tall cream-painted hopper swelling at the back, copper boiler and stovepipe exhaust.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
