Methods, apparatuses, data structures, and computer readable media are disclosed that represent network devices with encapsulated protocol stacks communicating via a common physical port. The dispensing machine includes a cabinet for containing a multitude of displacement pumps, where each displacement pump is realisably connected to a disposable pre-filled fluid cartridge. Base members 24 extend from the vertical members and are supported by angled braces 22. The work machine further includes a cab assembly mounted on the main frame such that the cab assembly is interposed between the engine assembly and the radiator assembly. Inner surfaces of the deflector may also be coated with low emissivity materials to reduce radiant heat flux transfer.
