Sounds like a new operator needs to be in his future. One that can operate and maintain a track machine! You are worried about tracks leaving marks, but tires and chains are your answer? really! I have had Zero trouble in the snow (everyone will have problems on ice except the chains), and actually prefer my track machine over my tire machine. If you are having issues throwing tracks, fire the ahole that can’t recognize the tracks are loose and hire someone that cares and can fix it before they fall off. Or stop being a cheap skate and replace them when they need to be replaced! And yes white tracks are non marking normally and Turf tracks (green) are extremely turf friendly, but don’t hold up very well on paved surfaces from what I gather.
Even in marginally wet conditions with a job set up properly I would put my DW trip for trip against the avant. Speed and turf friendliness.
