Yes you can plow with a 150, but the full size plows you will have to be very careful with. You will beat the crap out of a 150 chassis if you just plow into the stuff. At the place my dad works at they have a boss adjustable v-blade on a bronco and it actually works great, its really weighs down the front tho on the light duty springs and you have to kinda easy into it of just hit it lightly. Tranny likes to get hot too but that might just be cause its a wore out tranny.
I've put a snowsport on a Blazer at work once for a customer. Went and played with it afterwords, and yea it works. Its the simplest thing ever to put on and put up and down, but the blade it very light. It will works great for smooth surfaces with light snow. But and heavy snow and it gonna be difficult cause the blade wants to go over top. Also i don't think it would work on grass areas too well.
