For it to have suffered damage from a land mine, wouldn't that mean the vehicle was a one shot deal - detonate one mine and it requires repairs? That would make for very slow progress
in clearing a path through a minefield. It's possible it was designed
to only handle anti-personnel type.
Judging from this photo, looks like the rollers are actually tires, so definitely can see these being ripped to shreds.
