I've seen plenty of photos of IDF use of the KMT 5 mine rollers. Did they use the KMT 6 plow too?

I don't know what kind exactly, but l think I've seen the same (or similar...?) plows on some Magachs... I'm not sure how extensively these were used though... Probably not much. Doesn't really seem to fit rocky and/or desert environment.
IDF combat engineering vehicles on the other hand (i.e. Puma) definitely use (a different kind of) mine plow.

Yes, The Pumas I've seen use a "regular" dozer blade (Urdan design I think) with some nasty, T-Rex looking teeth. Other photos I've seen show Puma and others using rollers, either older Russian KMT4s or An Israeli clone/improved version. KMT 6 strikes me as being more practical (Lighter/ more compct) for a vehicle , say patrolling a border area, than a big roller system.

Usually armored Hummers are deployed on border patrol duties, as the main threat is IED's, not anti tank mines. https://armorama.kitmaker.net/forums/161034&page=1
