I believe they recommend awd all the time for wear purposes. Certainly there are instances when turf mode and or 2wd will get you where your going but that is just what camso recommends. Once in awd it will keep the front engaged because there are different tooth counts on the drive sprockets, hence all four will dig and wear more consistently. I have on two instances drove in turf mode or 2wd. Once was the first time i drove another unit with tracks after installing them and the other mine. Once i got into just a bit of snow the rear dug and there i sat. Both times throwing it in awd pulled me right out and both times were a DOH moment.
As far as when to use high and low i guess these machines have enough power to pull through about most stuff. I feel high will get me in and out of a potential situation a bit quicker but then again i am just blasting around in the ditches and on flat ground. I monitor the belt temp on my machine and dont see elevated temps even in the deep stuff. Im hoping to take it to Wyoming this winter to play in the elevation and suspect I will have to run it in low some.
