It was something that Kukje came up with, since they run fully mechanical engines. Well, I'm not 100% sure that it was Kukje idea but I've only seen it on their engines.
With a common rail engine, would be very easy to just add the extra injector at the DPF for the regen process and control it electronically. On a mechanical engine, it's much to do that, so Kukje creates a restriction of the exhaust gases so it increases the temperature at the DPF.
There a bunch of these new Branson tractors already sold in the US using this system but I haven't heard anything whether this system works well or not.
