My opinion only.
It's a common issue with all solid rail track systems. aggravated even more with luggy "dirt" tracks that most CTL units come with. Those big block tracks should be abolished. LOL. Great in gravel & dirt, but not much else.
I've tried a few CTL's, some with studs, and never again. The tracks and solid rail tubs were never designed for winter ice & snow operations. Adding studs tore up the shop floor and the track itself over time. Spending some $$ for all weather tracks definitely helps but doesn't solve the issue completely..
IMHO, best options for snow removal.
-ASV tracked units - ( ASV supplied track systems to Terex & CAT for a few years) Full floating track rail suspension and a true all weather track design.
- Any wheeled machine with narrow dedicated ice & snow grips.
