The RC Snow Plow is essentially a twist on the basic RC treaded vehicle in that it incorporates a plow feature.
The controls are simple skid steer meaning that each track has its own independent motor. This allows it to turn on the spot. Along with that there is a motor which raises and lowers the plow at the front.
This toy would be for ages 5+ or so . Thus the structure of the vehicle must be sturdy enough to withstand abuse, so some form of plastic would suffice. More importantly it needs to be nearly airtight in order to keep out water or whatever else is being pushed. Along with this the motors need to have cut off switches in case it comes across an obstacle it cannot push.
